Question

当我运行它时，我得到了这个：

我在IIS，SQL Server中启用了Windows身份验证，并在web.config中添加了身份验证方法：

<system.web>
  <authentication mode="Windows"/>
<system.web>

我完全没有想法......

如您所见，DataConnection正在运行

DataConnection Screenshot

来自web.config的连接字符串：

<connectionStrings>
    <clear/>
    <add name="cafeaconnection" 
         connectionString="Data source=LENOVO-PC\SQLEXPRESS; Initial catalog=tipuridecafeaDB; user id=user; password=password; persist security info=True;" 
         providerName="System.Data.SqlClient" />
    <add name="ConnectionString" 
         connectionString="Data Source=(LocalDB)\MSSQLLocalDB;AttachDbFilename=|DataDirectory|\tipuridecafeaDB.mdf;Integrated Security=True" 
         providerName="System.Data.SqlClient"/>
</connectionStrings>

错误：
