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")
    VB.NET异常迭代捕捉的相关代码编写方法就为大家介绍到这里。
