我发现前两个的错误的地址是我自己机器的地址 ，SQLHelperBLL是我WTi_BLL的一个类，我检查了14,行。代码是
string connectstr = ConfigurationManager.ConnectionStrings["Connectstr"].ConnectionString;
这个怎么解决啊？？？？
堆栈跟踪:
[NullReferenceException: 未将对象引用设置到对象的实例。]

------解决方案--------------------
哪就得换种方式了。
简单点儿还是
EnableEventValidation="false"
确保你的web.config 有Connectstr值
写在web.config中
后台获取的时候用
configurationManager.connectionString["Connectstr"].ToString()
Web.config中加入
- XML code
<connectionStrings> <add name="Connectstr" connectionString="Data Source=.;Initial Catalog=数据库名字;User ID=账号;Password=密码" providerName="System.Data.SqlClient" /> </connectionStrings>
