抱歉发错帖子

其次，我运行 c# 代码如下：

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();
    }
}

关键是我使用 SqlCommand 作为全局变量启动一次，所以当我使用两次更新方法或 GetByID 方法时，SQLCommand 变量也保留旧参数。因此，当您传递的参数超过 SP 需要 时，您会收到上述错误，所以我简单地添加了： cmd.Parameters.Clear(); 在每个方法的开头。

现在它工作正常。

该错误通常表示具有比您的 SP 定义的更多的参数。

由于您没有提供足够的代码来确定地告诉您（提供更多的 cmd 代码块和至少 SP 的定义），我认为是这种情况。尤其是在提供了这么多参数的情况下。

我确实读到这也可能是处理 SqlDatasources 时引起的潜在问题。但是，由于您提供的代码有限，我只是指出这是一种可能性。
