sqlHelper 类型初始值设定项引发异常

<?xml version="1.0" encoding="utf-8" ?>

  <appSettings>
    <add key="connectionStr" value="Data Source=192.168.12.149;Initial Catalog=hnwisdbnew_20100128;User ID=sa;Pwd=123"/>

public static void Ini()
        {
            string connectionStr = ConfigurationSettings.AppSettings["connectionStr"].ToString();
            Application_Table = SqlHelper.ExecuteDataSet(connectionStr, "select * from tblsys_param");
            Application_Table.Tables[0].TableName = "SYSPARAM";
        }

他不进入到SqlHelper.ExecuteDataSet方法里面去。也知道怎么调试，异常就是sqlhelper类型初始值设定项引发异常

检查下你的SqlHelper
