ASP.NET 2.0

Configuration objConfig = WebConfigurationManager.OpenWebConfiguration("~");

AppSettingsSection objConSettings = (AppSettingsSection)objConfig.GetSection("connecti  onStrings");

if (objConSettings != null)

   {

      objConSettings.Settings["conString"].Value = "Ye Chizi";

      objConfig.Save();

   }

AppSettingsSection objConSettings = (AppSettingsSection)objConfig.GetSection("connecti  onStrings");

Unable to cast object of type 'System.Configuration.ConnectionStringsSection' to type 'System.Configuration.AppSettingsSection'.

Configuration objConfig = WebConfigurationManager.OpenWebConfiguration("~");

ConnectionStringsSection objConSettings = (ConnectionStringsSection)objConfig.GetSection("co  nnectionStrings");

if (objConSettings != null)

{

    objConSettings.ConnectionStrings["MyDB_DBConnectionString"].ConnectionString = "......";

    objConfig.Save();
