Hi, i have one ready made function in VB.Net but i want to use it in C#.Net.
So tell me converted Code.

The code is,

Imports System.Convert

Partial Class EncDec
    Inherits System.Web.UI.Page

  

    Public Function SimpleEncrypt(ByVal TheText As String) As String
        Dim tempChar As String = Nothing
        Dim i As Integer = 0
        For i = 1 To TheText.Length
            If ToInt32(TheText.Chars(i - 1)) < 128 Then
                tempChar = System.Convert.ToString(ToInt32(TheText.Chars(i - 1)) + 100)
            ElseIf ToInt32(TheText.Chars(i - 1)) > 128 Then
                tempChar = System.Convert.ToString(ToInt32(TheText.Chars(i - 1)) - 100)
            End If
            TheText = TheText.Remove(i - 1, 1).Insert(i - 1, (CChar(ChrW(tempChar))).ToString())
        Next i
        Return TheText
    End Function

    Protected Sub butSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles butSubmit.Click
        If TextBox1.Text = "admin" Then
            txtResult.Text = SimpleEncrypt(txtText.Text)
        Else
            Label1.Text = "Enter Correct Password"
        End If

        'txtResult.Visible = True
        'butDecrypt.Visible = True
        'txtText.Visible = False
        'butSubmit.Visible = False
    End Sub

    Protected Sub butDecrypt_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles butDecrypt.Click
        If TextBox2.Text = "admin" Then
            txtText.Text = SimpleEncrypt(txtResult.Text)
        Else
            Label1.Text = "Enter Correct Password"

        End If

        'txtText.Visible = True
        'butSubmit.Visible = True
        'txtResult.Visible = False
        'butDecrypt.Visible = False
    End Sub

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

    End Sub
End Class
