c# - Entity Framework 从存储过程返回错误的值

Question

我有这个 SQL Server 存储过程:

    @UserName VARCHAR(MAX),
    @Result INT
AS
BEGIN
    SET NOCOUNT ON;

    SELECT LoginID 
    FROM Personnel
    WHERE LoginID = @UserName AND Administrator = 'Y'

    SET @Result = @@ROWCOUNT

    RETURN @Result
END

当我测试它时，我得到了预期的结果，我得到 1 行或 0 行计数。

我使用以下代码从 C# 应用程序调用存储过程:

private void ValidateUser(string user)
{
    using (ComplaintsEntities db = new ComplaintsEntities())
    {
        var t = db.AAGetAdminStatus(user,0);
    }
}

当我使用良好的用户帐户进行测试时，我应该得到 1 结果，如果我的用户不是管理员，我应该得到 0 结果。当我检查 C# 代码中的返回值时，它总是返回 -1。我怎样才能让它发挥作用？

Answer 1

@UserName varchar(max)
AS
BEGIN
  -- SET NOCOUNT ON added to prevent extra result sets from
  -- interfering with SELECT statements.
  SET NOCOUNT ON;

  -- Insert statements for procedure here
  Select count(LoginID) UserCount
  from Personnel
  where LoginID = @UserName And Administrator = 'Y'

END

实体代码:

private void ValidateUser(string user)
{
    using (ComplaintsEntities db = new ComplaintsEntities())
    {
        var t = db.AAGetAdminStatus(user).First().UserCount;
    }
}
