vb.net文字转编码,vbs编码转换
vb.net怎么把汉字转换为GB2312编码,例如“武汉”变成%CE%E4%BA%BA。希望那位好人能解,最好详细点,,,
这是HtmlEncode 不是GB2312编码~

一般用于URL传递
System.Web.HttpUtility.HtmlEncode(“武汉”)
System.WebHttpUtility.HtmlDecode(“%CE%E4%BA%BA”)
vb.net 如何将编码GB2312转成UTF8
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
说明:strData参数是GB2312字符串,函数返回UTF8字节数组

GB2312是GBK编码的子集,使用GBK编码函数即可
'GBK编码(结果以百分号%进行分隔)
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
End Function
vb.net中string 转 unicode 编码
Unicode编码是一个数组,其中每个元素代表一个位码,还有ASCII和UTF8两种编码格式。
Unicode:
Dim bytes() As Byte() = System.Text.Encoding.Unicode.GetBytes("字符串")
ASCII:
Dim bytes() As Byte() = System.Text.Encoding.ASCII.GetBytes("字符串")
UTF8:
Dim bytes() As Byte() = System.Text.Encoding.UTF8.GetBytes("字符串")

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
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。
