Question

我使用visual studio和c＃win表单（web表单）。我尝试打开连接到MS 2005 Server和reader query.here - 是

sql = "SELECT Files.ID, Files.FileName, Files.File_Name, Files.CreatingDate, aspnet_Users.UserName, aspnet_Membership.Email "
+ "FROM aspnet_Membership "
+ "INNER JOIN aspnet_Users ON aspnet_Membership.UserId = aspnet_Users.UserId "
+ "INNER JOIN Files ON aspnet_Membership.UserId = Files.UserId";

这些表存在于数据库中。无效的对象名称'aspnet_Membership'。描述：执行当前Web请求期间发生未处理的异常。请查看堆栈跟踪以获取有关错误及其源自代码的位置的更多信息。

异常详细信息：System.Data.SqlClient.SqlException：无效的对象名称'aspnet_Membership'。

来源错误：

Line 47:             SqlCommand cmd = new SqlCommand(sql, con);
Line 48:             con.Open();
Line 49:             SqlDataReader reader = cmd.ExecuteReader();
Line 50:             string str = "";

我很沮丧。提前致谢

Answer 1

表aspnet_Membership要么不存在，要么无法访问。使用SQL Server Management Studio确定它是否存在。也可能是您连接到错误的数据库。仔细检查您的连接字符串

无效的对象名称'aspnet_Membership'
