网站配置一般用来保存网站的一些设置,写在配置文件中比写在数据库中要合适一下,因为配置文件本身带有缓存,随网站启动读入缓存中,速度更快,而保存在数据库中要单独为一条记录创建一个表,结构不够清晰,而且读写也没有配置文件容易实现。这次要做的是网站的基本信息,数据保存在SiteConfig.config。
在14年的时候写过一篇博客《.Net MVC 网站中配置文件的读写》 ,在那篇博客中把思路和方法都已经写清楚了,这次的实现思路和上次一样,只是那次自己实现了KeyValueElement类和KeyValueElementCollection类,其实这两个类在System.Configuration命名空间中都已经实现,直接使用就行。
一、网站配置类(SiteConfig)
1、在Nninesky.Core项目新建文件夹Config
2、在Config文件夹添加类SiteConfig。

using System.ComponentModel.DataAnnotations; using System.Configuration; namespace Ninesky.Core.Config { /// <summary> /// 网站配置类 /// </summary> public class SiteConfig : ConfigurationSection { private static ConfigurationProperty _property = new ConfigurationProperty( string .Empty, typeof (KeyValueConfigurationCollection), null , ConfigurationPropertyOptions.IsDefaultCollection); [ConfigurationProperty( "" , Options = ConfigurationPropertyOptions.IsDefaultCollection)] private KeyValueConfigurationCollection keyValues { get { return (KeyValueConfigurationCollection) base [_property]; } set { base [_property] = value; } } /// <summary> ///网站名称 /// </summary> [Required(ErrorMessage = "*" )] [StringLength(50, ErrorMessage = "最多{1}个字符" )] [Display(Name = "网站名称" )] public string SiteName { get { return keyValues[ "SiteName" ] == null ? string .Empty: keyValues[ "SiteName" ].Value; } set { keyValues[ "SiteName" ].Value = value; } } /// <summary> ///网站标题 /// </summary> [Required(ErrorMessage = "*" )] [StringLength(50, ErrorMessage = "最多{1}个字符" )] [Display(Name = "网站标题" )] public string SiteTitle { get { return keyValues[ "SiteTitle" ] == null ? string .Empty: keyValues[ "SiteTitle" ].Value; } set { keyValues[ "SiteTitle" ].Value = value; } } /// <summary> ///网站地址 /// </summary> [DataType(DataType.Url)] [Required(ErrorMessage = "*" )] [StringLength(500, ErrorMessage = "最多{1}个字符" )] [Display(Name = "网站地址" )] public string SiteUrl { get { return keyValues[ "SiteUrl" ] == null ? "http://" : keyValues[ "SiteUrl" ].Value; } set { keyValues[ "SiteUrl" ].Value = value; } } /// <summary> ///Meta关键词 /// </summary> [DataType(DataType.MultilineText)] [StringLength(500, ErrorMessage = "最多{1}个字符" )] [Display(Name = "Meta关键词" )] public string MetaKeywords { get { return keyValues[ "MetaKeywords" ] == null ? string .Empty: keyValues[ "MetaKeywords" ].Value; } set { keyValues[ "MetaKeywords" ].Value = value; } } /// <summary> ///Meta描述 /// </summary> [DataType(DataType.MultilineText)] [StringLength(1000, ErrorMessage = "最多{1}个字符" )] [Display(Name = "Meta描述" )] public string MetaDescription { get { return keyValues[ "MetaDescription" ] == null ? string .Empty : keyValues[ "MetaDescription" ].Value; } set { keyValues[ "MetaDescription" ].Value = value; } } /// <summary> ///版权信息 /// </summary> [DataType(DataType.MultilineText)] [StringLength(1000, ErrorMessage = "最多{1}个字符" )] [Display(Name = "版权信息" )] public string Copyright { get { return keyValues[ "Copyright" ] == null ? "Ninesky 版权所有" : keyValues[ "Copyright" ].Value; } set { keyValues[ "Copyright" ].Value = value; } } } } |
Siteconfig类继承自ConfigurationSection,继承自这个类是才能读写配置节。
在类中声明一个配置元素的子元素 private static ConfigurationProperty _property,子元素的配置实体类型是KeyValueConfigurationCollection(键/值集合)。
然后徐再在类中声明一个属性private KeyValueConfigurationCollection keyValues。利用keyValues获取、设置配置节键/值集合。

[ConfigurationProperty( "" , Options = ConfigurationPropertyOptions.IsDefaultCollection)] private KeyValueConfigurationCollection keyValues { get { return (KeyValueConfigurationCollection) base [_property]; } set { base [_property] = value; } } |
然后就可以使用keyValues[“name”]获取设置具体配置了。

/// <summary> ///网站名称 /// </summary> [Required(ErrorMessage = "*" )] [StringLength(50, ErrorMessage = "最多{1}个字符" )] [Display(Name = "网站名称" )] public string SiteName { get { return keyValues[ "SiteName" ] == null ? string .Empty: keyValues[ "SiteName" ].Value; } set { keyValues[ "SiteName" ].Value = value; } } |
看起来是不是跟其他模型类差不多,知识Get;Set;有所不同。
二、设置配置文件的类型和路径
打开Nniesky.web项目的 web.config文件,找到configSections,然后添加SiteConfig配置节
红框部分为添加类型,说明了配置节的名称和类型,注意红线部分,restartOnExternalChanges设为"false",如果不设置,配置文件修改后会重启网站。
在配置文件的结尾</configuration>添加配置文件的路径
图中红框部分为添加内容,指明SiteConfig的位置文件在网站目录Config文件夹下名为SiteConfig.config的文件。
然后在项目中添加Config文件夹,然后添加名为SiteConfig.config的配置文件。

<? xml version = "1.0" encoding = "utf-8" ?> < SiteConfig > < add key = "SiteName" value = "Ninesky" /> < add key = "SiteTitle" value = "1133" /> < add key = "SiteUrl" value = "http://mzwhj.cnblogs.com" /> < add key = "MetaKeywords" value = "关键词," /> < add key = "MetaDescription" value = "描述" /> < add key = "Copyright" value="Ninesky 版权所有<a>11</ a >" /> </ SiteConfig > |
配置文件中的键名与SiteConfig的属性名对应。
三、控制器和视图
1、配置文件的读取
在Ninesky.Web/Areas/Control/Controllers【右键】->添加->控制器,输入控制器名ConfigController。
在控制其中添加方法SiteConfig方法

代码很简单,利用WebConfigurationManager的GetSection方法就将配置信息读出来了。
右键添加视图,将个属性显示出来。

@model Ninesky.Core.Config.SiteConfig @{ ViewBag.Title = "站点设置" ; } @section SideNav{@Html.Partial( "SideNavPartialView" )} <ol class = "breadcrumb" > <li><span class = "glyphicon glyphicon-home" ></span> @Html.ActionLink( "首页" , "Index" , "Home" )</li> <li>@Html.ActionLink( "系统设置" , "Index" )</li> <li class = "active" >站点设置</li> </ol> @ using (Html.BeginForm()) { @Html.AntiForgeryToken() <div class = "form-horizontal" > @Html.ValidationSummary( true , "" , new { @ class = "text-danger" }) <div class = "form-group" > @Html.LabelFor(model => model.SiteName, htmlAttributes: new { @ class = "control-label col-md-2" }) <div class = "col-md-10" > @Html.EditorFor(model => model.SiteName, new { htmlAttributes = new { @ class = "form-control" } }) @Html.ValidationMessageFor(model => model.SiteName, "" , new { @ class = "text-danger" }) </div> </div> <div class = "form-group" > @Html.LabelFor(model => model.SiteTitle, htmlAttributes: new { @ class = "control-label col-md-2" }) <div class = "col-md-10" > @Html.EditorFor(model => model.SiteTitle, new { htmlAttributes = new { @ class = "form-control" } }) @Html.ValidationMessageFor(model => model.SiteTitle, "" , new { @ class = "text-danger" }) </div> </div> <div class = "form-group" > @Html.LabelFor(model => model.SiteUrl, htmlAttributes: new { @ class = "control-label col-md-2" }) <div class = "col-md-10" > @Html.EditorFor(model => model.SiteUrl, new { htmlAttributes = new { @ class = "form-control" } }) @Html.ValidationMessageFor(model => model.SiteUrl, "" , new { @ class = "text-danger" }) </div> </div> <div class = "form-group" > @Html.LabelFor(model => model.MetaKeywords, htmlAttributes: new { @ class = "control-label col-md-2" }) <div class = "col-md-10" > @Html.EditorFor(model => model.MetaKeywords, new { htmlAttributes = new { @ class = "form-control" } }) @Html.ValidationMessageFor(model => model.MetaKeywords, "" , new { @ class = "text-danger" }) </div> </div> <div class = "form-group" > @Html.LabelFor(model => model.MetaDescription, htmlAttributes: new { @ class = "control-label col-md-2" }) <div class = "col-md-10" > @Html.EditorFor(model => model.MetaDescription, new { htmlAttributes = new { @ class = "form-control" } }) @Html.ValidationMessageFor(model => model.MetaDescription, "" , new { @ class = "text-danger" }) </div> </div> <div class = "form-group" > @Html.LabelFor(model => model.Copyright, htmlAttributes: new { @ class = "control-label col-md-2" }) <div class = "col-md-10" > @Html.EditorFor(model => model.Copyright, new { htmlAttributes = new { @ class = "form-control" } }) @Html.ValidationMessageFor(model => model.Copyright, "" , new { @ class = "text-danger" }) </div> </div> <div class = "form-group" > <div class = "col-md-offset-2 col-md-10" > <input type= "submit" value= "保存" class = "btn btn-default" /> </div> </div> </div> } |
2、配置文件的保存。
在控制器中再添加一个[HttpPost]类型的SiteConfig方法。
- [ValidateInput(false)]
- [ValidateAntiForgeryToken]
- [HttpPost]
- public ActionResult SiteConfig(FormCollection form)
- {
- SiteConfig _siteConfig = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("~").GetSection("SiteConfig") as Ninesky.Core.Config.SiteConfig;
- if (TryUpdateModel<SiteConfig>(_siteConfig))
- {
- _siteConfig.CurrentConfiguration.Save();
- return View("Prompt", new Prompt() { Title = "修改成功", Message = "成功修改了网站设置", Buttons = new List<string> { "<a href='"+Url.Action("SiteConfig") +"' class='btn btn-default'>返回</a>" } });
- }
- else return View(_siteConfig);
- }
- }
代码也非常简单,与读取配置文件相同,使用WebConfigurationManager的GetSection方法将配置信息读入_siteConfig中,然后用TryUpdateModel<SiteConfig>(_siteConfig)绑定视图提交过来的信息。
如果绑定成功,利用_siteConfig.CurrentConfiguration.Save()方法保存配置信息(这个方法继承自ConfigurationSection,不用自己实现)。
效果如下图
