VB.NET CompareInfo.Compare方法代码示例

' The following code example compares two strings using the different CompareInfo instances:
'    a CompareInfo instance associated with the "Spanish - Spain" culture with international sort,
'    a CompareInfo instance associated with the "Spanish - Spain" culture with traditional sort, and
'    a CompareInfo instance associated with the InvariantCulture.
