Answer 1:

对不起，错后

所有第二，我跑的C＃代码如下所示：

public class MemberD
{
    public SqlCommand cmd = new SqlCommand();
    public SqlConnection con = new SqlConnection("ConStr");
    public SqlDataReader dr;

    public void UpdateMember(string CODE, int COCODE, Member user)
    {
        cmd.Parameters.Clear(); // Here's  the solution

        //Here I added my SQL parameters 
        cmd.CommandType = System.Data.CommandType.StoredProcedure;
        cmd.CommandText = "SP_MSMEMBERS_UPDATE";
        cmd.Connection = con;
        con.Open();
        cmd.ExecuteNonQuery();

        con.Close();
    }
}

问题的关键是使用的SqlCommand作为全局变量初始化一次，所以当我使用Update方法两次或两次GetByID方法例如，SqlCommand的变量保持旧的参数，以及，即时通讯。所以，当你传递参数超过SP需要你得到上面的错误，所以干脆我说：cmd.Parameters.Clear（）; 在每个方法的开始。

现在它的工作的罚款。

Answer 2:

该错误通常代表比你的SP已经定义了多个参数。

由于您没有提供足够的代码来告诉你肯定（提供更多的CMD代码块和至少SP的定义），我会假设它是这种情况。特别是随着供应这么多的争论。

我看过，这也可与SqlDatasources打交道时所引起的潜在问题。然而，由于提供的有限的代码，我只是指出这一点的可能性。
