使用C#实现读取系统配置文件的代码实例讲解

    Configuration cfa = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);


    if (addrService != "")
    {
     cfa.AppSettings.Settings["WebServiceUrl"].Value = addrService;
    }
    if (setLogin != "")
    {
     cfa.AppSettings.Settings["LoginServerUrl"].Value = setLogin;
    }
    if (mapPath != "")
    {
     cfa.AppSettings.Settings["InitMapPath"].Value = mapPath;
    }


    cfa.Save(ConfigurationSaveMode.Modified);
    //重新加载配置文件
    ConfigurationManager.RefreshSection("appSettings");  

<pre name="code" class="csharp">    string value = ConfigurationSettings.AppSettings["InitMapPath"];</pre>
