VB.NET异常迭代捕捉代码示例
所有编程语言在实际开发中都会出现一些异常,编程人员在代码编写时也会考虑到这些异常的出现做出相应的处理。在VB.NET里,同样需要进行一些异常处理。我们在这里就先为大家介绍一下VB.NET异常迭代捕捉的相关方法。
VB.NET异常迭代捕捉代码示例:
Dim a As Integer = 10
Dim b As Integer = 20
Dim c As Integer = 10
Dim i As Integer
Dim liu As Integer
Dim aaa As New System.
Text.StringBuilder
Try For i = 0 To 20
If b < 10 Then aa = a + 1
Try
liu = (b / (a - c))
aaa.AppendLine("ok:" & b.ToString)
Exit For
Catch ex As Exception
aaa.AppendLine("error:" & b.ToString)
bb = b - 1
If b < 15 Then Throw New Exception("error")
End If
End Try
Next
Me.TextBox1.Text = aaa.ToString
Catch ex As Exception MsgBox("oooo")
End Try
MsgBox(b.ToString)
MsgBox("www")
