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
开发者ID:VB.NET开发者,项目名称:System.Text,代码行数:17,代码来源:UnicodeEncoding.GetByteCount 输出:
Bytes needed to encode 'UTF-16 Encoding Example':
Maximum: 48
Actual: 46
Actual with BOM: 48
示例2: Example
' 导入命名空间
Imports System.Text
Module Example
Public Sub Main()
Dim uppercaseStart As Integer = &h0041
Dim uppercaseEnd As Integer = &h005a
Dim lowercaseStart As Integer = &h0061
Dim lowercaseEnd As Integer = &h007a
' Instantiate a UTF8 encoding object with BOM support.
Dim unicode As Encoding = Encoding.Unicode
' Populate array with characters.
Dim chars(lowercaseEnd - lowercaseStart + uppercaseEnd - uppercaseStart + 1) As Char
Dim index As Integer = 0
For ctr As Integer = uppercaseStart To uppercaseEnd
chars(index) = ChrW(ctr)
index += 1
Next
For ctr As Integer = lowercaseStart To lowercaseEnd
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,
lowercaseEnd - lowercaseStart + 1))
Console.WriteLine(" Actual with BOM: {0,5:N0}",
unicode.GetByteCount(chars, uppercaseEnd - uppercaseStart + 1,
lowercaseEnd - lowercaseStart + 1) +
unicode.GetPreamble().Length)
End Sub
End Module
开发者ID:VB.NET开发者,项目名称:System.Text,代码行数:37,代码来源:UnicodeEncoding.GetByteCount 输出:
Bytes needed for lowercase Latin characters:
Maximum: 54
Actual: 52
Actual with BOM: 54
