示例1: Example

' 导入命名空间
Imports System.Globalization

Public Module Example
   Public Sub Main()
      Dim str1 As String = "indigo"
      Dim str2, str3 As String
      
      ' str2 is an uppercase copy of str1, using English-United States culture.
      str2 = str1.ToUpper(New CultureInfo("en-US", False))
      
      ' str3 is an uppercase copy of str1, using Turkish-Turkey culture.
      str3 = str1.ToUpper(New CultureInfo("tr-TR", False))
      
      ' Compare the code points and compare the uppercase strings.
      ShowCodePoints("str1", str1)
      ShowCodePoints("str2", str2)
      ShowCodePoints("str3", str3)
      Console.WriteLine("str2 is {0} to str3.", _
                        IIf(String.CompareOrdinal(str2, str3) = 0, "equal", "not equal"))
   End Sub
   
   Public Sub ShowCodePoints(varName As String, s As String)
      Console.Write("{0} = {1}: ", varName, s)
      For Each c In s
         Console.Write("{0:X4} ", AscW(c))
