示例1: Example

' 导入命名空间
Imports System.Text

Module Example
    Public Sub Main()
        Dim chars As String = "UTF-16 Encoding Example"
        Dim unicode As Encoding = Encoding.Unicode

        Console.WriteLine("Bytes needed to encode '{0}':", chars)
        Console.WriteLine("   Maximum:         {0}",
                          unicode.GetMaxByteCount(chars.Length))
        Console.WriteLine("   Actual:          {0}",
                          unicode.GetByteCount(chars))
        Console.WriteLine("   Actual with BOM: {0}",
                          unicode.GetByteCount(chars) + unicode.GetPreamble().Length)
    End Sub
End Module

         chars(index) = ChrW(ctr)
         index += 1
      Next

      ' Display the bytes needed for the lowercase characters.
        Console.WriteLine("Bytes needed for lowercase Latin characters:")
        Console.WriteLine("   Maximum:         {0,5:N0}",
                          unicode.GetMaxByteCount(lowercaseEnd - lowercaseStart + 1))
        Console.WriteLine("   Actual:          {0,5:N0}",
                          unicode.GetByteCount(chars, uppercaseEnd - uppercaseStart + 1,
