asp.net預設的編碼為utf-8，當與其它平台互動處理的字元串中有中文時往往會出現亂碼，這是由于其它平台多采取GB2312編碼，要解決這一問題，可編寫一個函數，對字元串先轉換再處理就行了，下面是該函數的源代碼：Imports System.Math
Function URLEncoding(ByVal vstrIn As String)
Dim strReturn As String
strReturn = ""
Dim i As Integer
Dim ThisChr As String
Dim innerCode, Hight8, Low8 As Integer
For i = 1 To vstrIn.Length
ThisChr = Mid(vstrIn, i, 1)
If Abs(Asc(ThisChr)) < &HFF Then
strReturn = strReturn & ThisChr
Else
innerCode = Asc(ThisChr)
If innerCode < 0 Then
innerCode = innerCode + &H10000
End If
Hight8 = (innerCode And &HFF00) / &HFF
Low8 = innerCode And &HFF
strReturn = strReturn & "%" & Hex(Hight8) & "%" & Hex(Low8)
End If
Next
URLEncoding = strReturn
End Function
