Winform下APP.config问题
有2 个project
project1--取数据---> project2
说明：project1通过project2取数据
project1为主程式，project2专用处理数据，且生成为类库
project2中有一个App.config：
<?xml version= "1.0 " encoding= "utf-8 " ?>
<configuration>
<appSettings>
<add key= "ConnectionString " value= "Data Source=KYLEYUAN;Initial Catalog=WiseChamp;User ID=sa "/>
</appSettings>
</configuration>
=================可以正常显示网格数据
public sealed class DataAccess
{
private static string connectoinString = System.Configuration.ConfigurationManager.AppSettings[ "ConnectionString "];
//此处 connectionString=null;
private static SqlConnection cnn = new SqlConnection(connectoinString);
}
上面的类中取到的connectionString=null;
如果在project1中传一个connectionString过去，又会多出很多代码来....

[解决办法]
System.Configuration.ConfigurationSettings.AppSettings[ "connectionStrings "]
