如何用 VB 或 VB.Net 来撰写 ASP 的 Server.URLencode 函数

请参考底下做法:VB.Net 程式码如下 :Public Function URLEncode(ByRef strEnc As String) As StringDim strTmp2, strChar, strTmp, strRet As StringDim lngLoop As IntegerFor lngLoop = 0 To strEnc.Length - 1strChar = strEnc.Substring(lngLoop, 1)Select Case Asc(strChar)Case 48 To 57, 65 To 90, 97 To 122strRet = strCharCase 32strRet = "+"Case ElsestrTmp = Hex(Asc(strChar))If strTmp.Length 4 Then strTmp = strTmp.Substring(4)strRet = "%" strTmp.Substring(0, 2)If strTmp.Length 2 ThenstrTmp2 = strTmp.Substring(2)strRet = IIf(IsNumeric(strTmp.Substring(2, 1)), Chr(Val("H" strTmp2)), "%" strTmp2)End IfEnd SelectNextURLEncode = strRetEnd Function或Public Function URLenc(ByVal strEnc As String) As StringDim lngLoop, lngAsc As LongDim strChr As StringFor lngLoop = 0 To strEnc.Length - 1strChr = strEnc.Substring(lngLoop, 1)If Math.Abs(Asc(strChr)) 255 ThenURLenc = strChrElselngAsc = Asc(strChr)If lngAsc 0 Then lngAsc = lngAsc + 65536URLenc = "%" Hex((lngAsc And -256) \ 255) "%" Hex(lngAsc And 255)End IfNextEnd Function呼叫:MessageBox.Show(URLEncode("强力鎯头 PowerHammer !"))MessageBox.Show(URLenc("强力鎯头 PowerHammer !"))结果显示 :%B1j%A4O%EE%CF%C0Y+PowerHammer+%21%B1%6A%A4%4F%EE%CF%C0%59 PowerHammer ! ================================================================VB6 程式码如下 :Public Function URLEncode(strEnc As String) As StringDim strChar As String, strTmp As String, strTmp2 As String, strRet As StringDim lngLoop As LongFor lngLoop = 1 To Len(strEnc)strChar = Mid(strEnc, lngLoop, 1)Select Case Asc(strChar)Case 48 To 57, 65 To 90, 97 To 122strRet = strRet strCharCase 32strRet = strRet "+"Case ElsestrTmp = Format(Hex(Asc(strChar)), "00")strRet = strRet "%" Left(strTmp, 2)strTmp2 = Mid(strTmp, 3, 2)If Len(strTmp) 3 ThenstrRet = strRet IIf(IsNumeric(Mid(strTmp, 3, 1)), Chr(Val("H" strTmp2)), "%" strTmp2)End IfEnd SelectNextURLEncode = strRetEnd Function或Public Function URLenc(strEnc As String) As StringDim lngLoop As Long, lngAsc As LongDim strChr As StringFor lngLoop = 1 To Len(strEnc)strChr = Mid(strEnc, lngLoop, 1)If Abs(Asc(strChr)) 255 ThenURLenc = URLenc strChrElselngAsc = Asc(strChr)If lngAsc 0 Then lngAsc = lngAsc + 65536URLenc = URLenc "%" Hex((lngAsc And -256) \ 255) "%" Hex(lngAsc And 255)End IfNextEnd Function呼叫:MsgBox URLEncode("强力鎯头 PowerHammer !")MsgBox URLenc("强力鎯头 PowerHammer !")结果显示 :%B1j%A4O%EE%CF%C0Y+PowerHammer+%21%B1%6A%A4%4F%EE%CF%C0%59 PowerHammer ! ================================================================ASP 程式码如下(多此一举,因为ASP本来就有Server.URLencode) :Public Function URLEncode(strEnc)Dim strChr, intAsc, strTmp, strTmp2, strRet, lngLoopFor lngLoop = 1 To Len(strEnc)strChr = Mid(strEnc, lngLoop, 1)intAsc = Asc(strChr)If ((intAsc 58) And (intAsc 47)) Or ((intAsc 91) And (intAsc 64)) Or ((intAsc 123) And (intAsc 96)) ThenstrRet = strRet strChrElseIf intAsc = 32 ThenstrRet = strRet "+"ElsestrTmp = Hex(Asc(strChr))strRet = strRet "%" Right("00" Left(strTmp, 2), 2)strTmp2 = Mid(strTmp, 3, 2)If Len(strTmp) 3 ThenIf IsNumeric(Mid(strTmp, 3, 1)) ThenstrRet = strRet Chr(CInt("H" strTmp2))ElsestrRet = strRet "%" strTmp2End IfEnd IfEnd IfNextURLEncode = strRetEnd Function或Public Function URLenc(strEnc)Dim lngLoop, lngAsc, strChrFor lngLoop = 1 To Len(strEnc)strChr = Mid(strEnc, lngLoop, 1)If Abs(Asc(strChr)) 255 ThenURLenc = URLenc strChrElselngAsc = Asc(strChr)If lngAsc 0 Then lngAsc = lngAsc + 65536URLenc = URLenc "%" Hex((lngAsc And -256) \ 255) "%" Hex(lngAsc And 255)End IfNextEnd Function呼叫:Response.write URLEncode("强力鎯头 PowerHammer !")Response.write URLenc("强力鎯头 PowerHammer !")结果显示 :%B1j%A4O%EE%CF%C0Y+PowerHammer+%21%B1%6A%A4%4F%EE%CF%C0%59 PowerHammer !

使用vb点虐 编写一个函数，函数只有一个参数

首先在窗体上添加Button1，ListBox1，下面是完整代码

Public Class Form1

Public Sub BubbleSort(ByVal arr() As Integer) '冒泡法排序

Dim temp As Double

Dim i, j As Integer

For i = 0 To arr.GetUpperBound(0) - 1

For j = i + 1 To arr.GetUpperBound(0) - 1

If arr(i)  arr(j) Then

temp = arr(j)

arr(j) = arr(i)

arr(i) = temp

End If

Next

Next

End Sub

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click '调用

Dim arr() As Integer = {55, 22, 33, 11, 77, 88}

BubbleSort(arr) '调用排序过程

Me.ListBox1.Items.Clear()

For i = 0 To arr.GetUpperBound(0) - 1 '显示排序后结果

Me.ListBox1.Items.Add(arr(i).ToString)

Next

End Sub

End Class

vb点虐 编写一个函数

注意：参数为动态数组；

Private Function MyF(ByRef d() As Integer)

ReDim d(4, 13) As Integer

Dim i As Integer

Dim j As Integer

Dim n As Integer

Dim MyNum(4) As Integer

For i = 1 To 4

MyNum(i) = 0

Next i

Randomize

For i = 1 To 4

For j = 1 To 13

n = Int(Rnd * 4 + 1)

Do While MyNum(n) = 13

n = Int(Rnd * 4 + 1)

Loop

d(i, j) = n

MyNum(n) = MyNum(n) + 1

Next j

Next i

End Function
