VB 中连字符用 而不是 +。
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。
1、字节数组转换为字符串
byte[] byBuffer = new byte[20];
String strRead = new String(byBuffer);
strRead = String.copyValueOf(strRead.toCharArray(), 0, byBuffer.length]);
2、字符串转换成字节数组
byte[] byBuffer = new byte[200];
String strInput=abcdefg;
byBuffer= strInput.getBytes();
注意:如果字符串里面含有中文,要特别注意,在android系统下,默认是UTF8编码,一个中文字符相当于3个字节,只有gb2312下一个中文相当于2字节。这种情况下可采取以下办法:
