vb.netutf8的简单介绍

IT技术字符串

vb.net 将中文转UTF8的代码？谁有的帮帮我吧！根本都不是vb.netutf8你说的简单的UTF8编码问题vb.netutf8，人家是加密计算，下面的是UTF8编码转化函数
Private Function convert_UTF8(ByVal str As String) As String
Dim byt() As Byte = System.Text.Encoding.GetEncoding("Gb2312").GetBytes(str)
Return System.Text.Encoding.UTF8.GetString(byt)
End Function
vb.net 如何将编码GB2312转成UTF8Imports System.Text
Public Function StringAsUtf8Bytes(ByVal strData As String) As Byte()
Dim bytes() As Byte
bytes = Encoding.UTF8.GetBytes(strData)
Return bytes
End Function
说明：strData参数是GB2312字符串，函数返回UTF8字节数组
gb2312>unicode>utf8，以及逆转的方法'>VB.net 字符转换问题 字符（汉字、数字、字母、符号）>gb2312>unicode>utf8，以及逆转的方法字符编码转换吗?
1.字符与gb2312(gbk的子集)：
Public Function GBKEncode(ByVal sInput As String) As String
Dim ret_GBKEncode As String = ""
Dim i As Integer
Dim startIndex As Integer = 0
Dim endIndex As Integer
Dim x() As Byte = System.Text.Encoding.Default.GetBytes(sInput) '字符以及字符串在vb2008中都是以unicode编码存储的
endIndex = x.Length - 1
For i = startIndex To endIndex
ret_GBKEncode = "%"Hex(x(i))
Next
Return ret_GBKEncode
End Function
'GBK解码
Public Function GBKDecode(ByVal sInput As String) As String
sInput = sInput.Replace("%", "")
Dim ret_GBKDecode As String = ""
Dim sLen As Integer = sInput.Length
Dim n As Integer = sLen \ 2
Dim sBytes(0 To n - 1) As Byte
'转化为字节码
For i As Integer = 1 To n
sBytes(i - 1) = CByte("H"sInput.Substring(2 * i - 2, 2))
Next
'将字节码转化为字符串
ret_GBKDecode = System.Text.Encoding.Default.GetString(sBytes)
Return ret_GBKDecode
【vb.netutf8的简单介绍】End Function
2.Unicode字符串为UTF-8
Imports System.Text
Public Function StringAsUtf8Bytes(ByVal strData As String) As Byte()
Dim bytes() As Byte
bytes = Encoding.UTF8.GetBytes(strData)
Return bytes
End Function
'这里可以类推出好几种 。
