为什么说变量名@problem_type已经声明了呢
------解决方案--------------------------------------------------------
你的一个comm对象再次使用的时候要先
comm.Parameters.Clear();
因为你上次已经给了,

- C# code
楼上说的是，慢了一步 comm.CommandText = "update problem set problem_type=@problem_type,sameid_number=@sameid_number,way_self=@way_self,person_self=@person_self,date_fin=@date_fin,status_problem=@status_problem where id_number='" & Request.QueryString("id") & "'" [color=#FF0000]comm.Parameters.Clear();[/color] comm.Connection = conn comm.Parameters.Add("@problem_type", Data.SqlDbType.Int).Value = problemtype comm.Parameters.Add("@sameid_number", Data.SqlDbType.NChar).Value = Trim(TBProblemID.Text) comm.Parameters.Add("@way_self", Data.SqlDbType.NChar).Value = Trim(TBSolveContent.Text) comm.Parameters.Add("@person_self", Data.SqlDbType.NChar).Value = Session("username") comm.Parameters.Add("@date_fin", Data.SqlDbType.DateTime).Value = Now comm.Parameters.Add("@status_problem", Data.SqlDbType.Int).Value = solveeither comm.ExecuteNonQuery()
