从SQL Server 2008身份验证问题访问数据

我正在尝试连接到SQL Server。使用此代码从SQL Server 2008身份验证问题访问数据

public static String getDBConnection() 
    { 
     SqlConnectionStringBuilder csBuilder = new SqlConnectionStringBuilder(); 

     csBuilder.InitialCatalog = "AdDatabase"; 
     csBuilder.DataSource = "JAWADAMJAD-PC\\SQLEXPRESS"; 
     csBuilder.UserID = "Jawad"; 
     csBuilder.Password = "123456"; 

     return csBuilder.ConnectionString; 
    }

我已经通过SQL Server管理控制台添加了此用户名。我仍然无法弄清楚为什么我无法连接到SQL Server。我需要做其他事情才能成功连接吗？如果是这样的话是什么？请帮助！我使用Visual Studio 2010和SQL Server 2008

我收到以下异常

    at System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning(TdsParserStateObject stateObj)

我去了服务器日志，它说

An attempt to login as SQL Authentication Failed. Server is configured for windows authentication only.

您遇到的异常情况是什么？ – Vivasaayi

你有什么迹象表明这不成功？ – David

对不起，我忘了添加异常，我已将它添加到问题中。请查看 –

如果只有Windows身份验证模式，那么您需要将集成安全性选项设置为true并删除用户和密码。

System.Data.SqlClient.SqlConnectionStringBuilder构建器= new System.Data.SqlClient.SqlConnectionStringBuilder（）; builder [“Data Source”] =“（local）”; 构建器[“集成安全性”] = true; builder [“Initial Catalog”] =“AdventureWorks; NewValue = Bad”; Console.WriteLine（builder.ConnectionString）;

有关详细信息，请参阅http://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlconnectionstringbuilder.aspx
