vb.net字符处理 vbs字符串处理

vb.net 字符串的分解处理,将字符串中由数字和字母所组成的东东提取出来,并形成数组Imports System.Text.RegularExpressions
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim my_str As String = "3#@!Ab156(?*hLE\$"
Dim a() As String = Regex.Split(Regex.Replace(my_str, "^[\W] |[\W] $", ""), "\W ")
End Sub
End Class
vb.net 遇到多个字符串情况应该怎么处理select casestrings.right(S1,4)
case ".jpg",".bmp",".png"
vb.net字符处理你vb.net字符处理的处理代码
end select
string 里的功能很基本 。
strings类里有很多静态的字符串处理函数vb.net字符处理,很好用的vb.net字符处理,好好研究吧 。
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(gbkvb.net字符处理的子集)vb.net字符处理:
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
【vb.net字符处理 vbs字符串处理】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 。
