过程或函数“usp_SendEmails”需要参数“@SchedId”，但未提供

Question

这里是我的背后代码：

protected void gvviewapproval_RowUpdated(object sender, GridViewUpdatedEventArgs e) 
    { 
     using (SqlConnection cn = new SqlConnection(Utilities.ConnectionString())) 
     { 
      using (SqlCommand cmd = new SqlCommand("usp_SendEmails", cn)) 
      { 
       cn.Open(); 
       cmd.CommandType = CommandType.StoredProcedure; 
       cmd.ExecuteNonQuery(); 
      } 
     } 

     gvviewapproval.DataBind(); 
    } 
} 

Answer 1

您需要在执行前添加一个名为“@SchedId”的命令对象参数查询。

即

cmd.Parameters.AddWithValue("@SchedId", 3);
