问题描述

我在vb.net中托管了一个Asp网站.网站是所有关于计算平均值的事情，当两个用户打开我的网站并尝试进行任何计算时，它将显示RUNTIME错误.当一个用户使用该网站时，它可以正常工作.解决方案是什么.

使用组合框时，组合框中列出的项目是A，B，C.每个项目都具有10、9、8之类的值.
计算按钮以找到平均值.
当用户使用相同的组合框时会导致错误.

Dim tot1 As UInt32

Public Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
        tot1 = 21
        If DropDownList1.SelectedValue = 0 Then
            tot1 = tot1 - 3
        End If
        If DropDownList10.SelectedValue = 0 Then
            tot1 = tot1 - 3
        End If
        If DropDownList11.SelectedValue = 0 Then
            tot1 = tot1 - 3
        End If
        If DropDownList12.SelectedValue = 0 Then
            tot1 = tot1 - 4
        End If
        If DropDownList13.SelectedValue = 0 Then
            tot1 = tot1 - 4
        End If
        If DropDownList14.SelectedValue = 0 Then
            tot1 = tot1 - 2
        End If
        If DropDownList15.SelectedValue = 0 Then
            tot1 = tot1 - 2
        End If


        sem1 = ((DropDownList1.SelectedValue * 3) + (DropDownList10.SelectedValue * 3) + (DropDownList11.SelectedValue * 3) + (DropDownList12.SelectedValue * 4) + (DropDownList13.SelectedValue * 4) + (DropDownList14.SelectedValue * 2) + (DropDownList15.SelectedValue * 2)) / tot1
        TextBox1.Text = sem1

    End Sub

推荐答案

在您的web.config中设置customerror mode = off并让我们看到错误.

set customerror mode = off in your web.config and let us see the error.
