2005配置文件连接字符串的问题
APP.config文件：
<configuration>
<connectionStrings>
<add name= "SQLConnString " connectionString = "Data Source=kap;Initial Catalog=NorthWind;User ID=sa;pwd=sa " providerName= "System.Data.SqlClient "/>
</connectionStrings>

窗体中：
MessageBox.Show(System.Configuration.ConfigurationSettings.AppSettings.Get( "SQLConnString ").ToString)
和MessageBox.Show(System.Configuration.ConfigurationSettings.AppSettings( "SQLConnString ").ToString)

在运行时都报NULL，高手帮忙看一下

[解决办法]
<appSettings>
<add key= "ConnectionString " value= "server=192.168.0.249;database=NorthWind;uid=sa;pwd=sa "/>
</appSettings>

protected static string connectionString = ConfigurationSettings.AppSettings[ "ConnectionString "].ToString();
试试这种方式。
