第171行:string [] result1 = new string [2];
第172行:result1 = clsObj.FnUpdatedAccessNo(Session ["User_id"]，accessnumber，TextBoxDest.Text.Trim()，TextBoxRef.Text.Trim());
第173行:GridView1.EditIndex = -1;
第174行:lblStatus.Text =";


我的代码是:

推荐答案

您的FnUpdatedAccessNo方法的第一个参数是字符串.但是Session ["User_id"]是对象类型.您必须像这样转换它.
并且不要忘记它为null时不会转换，请检查其nullable

your FnUpdatedAccessNo methods first parameter is string. but Session["User_id"] is an object type. you must to convert it like this.
And dont forget when it was null it wont convert, check its nullable

string userId = "";
if(Session["User_id"] != null)
userId = Session["User_id"].ToString();
else userId = "";// default value 
result1 = clsObj.FnUpdatedAccessNo(userId, accessnumber, TextBoxDest.Text.Trim(), TextBoxRef.Text.Trim());

result1 = result1 = clsObj.FnUpdatedAccessNo(Convert.ToString(Session["User_id"]), accessnumber, TextBoxDest.Text.Trim(), TextBoxRef.Text.Trim()); 

请检查一下，让我知道是否对您有帮助.

谢谢
