布尔表达式的Abs

Question

在VB6中我有这样的代码：

  

IsLast = Abs（CursorPos = Len（numText.Text））

什么评价false为0，true为1。

这行代码在VB.NET中产生错误。

如何正确地写这个？

编辑： 错误是：

Error   15  Overload resolution failed because no accessible 'Abs' can be called without a narrowing conversion:
'Public Shared Function Abs(value As Decimal) As Decimal': Argument matching parameter 'value' narrows from 'Boolean' to 'Decimal'.
'Public Shared Function Abs(value As Double) As Double': Argument matching parameter 'value' narrows from 'Boolean' to 'Double'.
'Public Shared Function Abs(value As Single) As Single': Argument matching parameter 'value' narrows from 'Boolean' to 'Single'.
'Public Shared Function Abs(value As Long) As Long': Argument matching parameter 'value' narrows from 'Boolean' to 'Long'.
'Public Shared Function Abs(value As Integer) As Integer': Argument matching parameter 'value' narrows from 'Boolean' to 'Integer'.
'Public Shared Function Abs(value As Short) As Short': Argument matching parameter 'value' narrows from 'Boolean' to 'Short'.
'Public Shared Function Abs(value As SByte) As SByte': Argument matching parameter 'value' narrows from 'Boolean' to 'SByte'.

Answer 1

IsLast = If( CursorPos = Len(numText.Text), 1, 0 )

您是否尝试将较大的VB6块迁移到VB.Net？

Answer 2

IsLast = CursorPos = Len(numText.Text)
