有人可以帮我改个asp涵数吗
Function passwordEncrypt(origPassword)
Dim Stemp, I, L, X, Y
Randomize( hour(time()) * minute(time()) * second(time()) )
Stemp = Trim(origPassword)
L = Len(Stemp)
If L > 15 Or L = 0 Then
passwordEncrypt = Stemp
Else
passwordEncrypt = Chr(100 + L)
For I = 2 To (16 - L)
passwordEncrypt = passwordEncrypt & Chr(Fix(24 * Rnd(1)) + 98)
Next
For I = (16 - L + 1) To 16
X = Asc(Mid(Stemp, (I + L - 16), 1))
If X >= 48 And X <= 57 Or X >= 113 And X <= 122 Then
Y = 170 - X
ElseIf X >= 65 And X <= 80 Or X >= 97 And X <= 112 Then
Y = 177 - X
Else
Y = 171 - X
End If
passwordEncrypt = passwordEncrypt & Chr(Y)
Next
End If
End Function
我是asp.net C#的，有人可以帮我把上面那个涵数改成C#吗？谢谢了
------解决方案--------------------
我是用下列代码测试的,如果输入16位以内的字母和数字进行加密和解密是正确的.
Function passwordEncrypt(origPassword)
Dim Stemp, I, L, X, Y
Randomize( hour(time()) * minute(time()) * second(time()) )
Stemp = Trim(origPassword)
L = Len(Stemp)
If L > 15 Or L = 0 Then
passwordEncrypt = Stemp
Else
passwordEncrypt = Chr(100 + L)
For I = 2 To (16 - L)
passwordEncrypt = passwordEncrypt & Chr(Fix(24 * Rnd(1)) + 98)
Next
For I = (16 - L + 1) To 16
X = Asc(Mid(Stemp, (I + L - 16), 1))
If X >= 48 And X <= 57 Or X >= 113 And X <= 122 Then
Y = 170 - X
ElseIf X >= 65 And X <= 80 Or X >= 97 And X <= 112 Then
Y = 177 - X
Else
Y = 171 - X
End If
passwordEncrypt = passwordEncrypt & Chr(Y)
Next
End If
End Function
