Well, I recently got a program from csharp . But im not familiar with c# . I only got codes from vb.net . Is it possible if you guys help me to translate these following codes to C# ?

First set of codes, it will download the file from the page wroted[with replacing if there is a file with the same name existed]

Private Sub frmMain_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        lblProgress.Text = String.Empty
        txtURL.Text = URL_MESSAGE
        txtDownloadTo.Text = DIR_MESSAGE
        cmdGetFolder.Focus()
        txtURL.Hide()
        Show()
        Timer2.Start()

        cmdDownload.Enabled = False

        cmdDownload.Enabled = False
        cmdClose.Enabled = False

        'DO THE DOWNLOAD
        Try
            _Downloader = New WebFileDownloader

            _Downloader.DownloadFileWithProgress(txtURL.Text, ("") & filename)
        Catch ex As Exception
            MessageBox.Show("ERROR: " & ex.Message)
            cmdClose.Enabled = True
            cmdDownload.Enabled = True
        End Try
    End Sub

    'returns all text from last "/" in URL, but puts a "\" in front of the file name..
    Private Function GetFileNameFromURL(ByVal URL As String) As String
        If URL.IndexOf("/"c) = -1 Then Return String.Empty

        Return "\" & URL.Substring(URL.LastIndexOf("/"c) + 1)
    End Function

    'GET A FOLDER TO DOWNLOAD THE FILE TO
    Private Sub cmdGetFolder_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdGetFolder.Click
        If dlgFolderBrowse.ShowDialog(Me) <> DialogResult.Cancel Then
            txtDownloadTo.Text = dlgFolderBrowse.SelectedPath
        End If
    End Sub

    'FIRES WHEN WE HAVE GOTTEN THE DOWNLOAD SIZE, SO WE KNOW WHAT BOUNDS TO GIVE THE PROGRESS BAR
    Private Sub _Downloader_FileDownloadSizeObtained(ByVal iFileSize As Long) Handles _Downloader.FileDownloadSizeObtained
        ProgBar.Value = 0
        ProgBar.Maximum = Convert.ToInt32(iFileSize)
    End Sub

    'FIRES WHEN DOWNLOAD IS COMPLETE
    Private Sub _Downloader_FileDownloadComplete() Handles _Downloader.FileDownloadComplete
        ProgBar.Value = ProgBar.Maximum

        My.Settings.Save()
        'download.Show()
        yourlogo.Close()
        Process.Start(filename)

        cmdClose.Text = "Close"
        cmdClose.Enabled = True

        ProgBar.Value = ProgBar.Minimum
        lblProgress.Text = String.Empty
    End Sub

    'FIRES WHEN DOWNLOAD FAILES. PASSES IN EXCEPTION INFO
    Private Sub _Downloader_FileDownloadFailed(ByVal ex As System.Exception) Handles _Downloader.FileDownloadFailed
        MessageBox.Show("Error: " & ex.Message)
        cmdClose.Enabled = True
        cmdDownload.Enabled = True
    End Sub

    'FIRES WHEN MORE OF THE FILE HAS BEEN DOWNLOADED
    Private Sub _Downloader_AmountDownloadedChanged(ByVal iNewProgress As Long) Handles _Downloader.AmountDownloadedChanged
        ProgBar.Value = Convert.ToInt32(iNewProgress)
        lblProgress.Text = WebFileDownloader.FormatFileSize(iNewProgress) & " of " & WebFileDownloader.FormatFileSize(ProgBar.Maximum) & " Downloaded."
        Application.DoEvents()
    End Sub

Here is second set of code. I'd like to convert it to c# too .
This set of code will detects if the file version is the same , if it does not match , it will goto patcher form or else it will continue the application.

Private Sub CheckUpdata(ByVal url As String)

        WebClient1.DownloadFileAsync(New Uri(url), "updateinfo.ver")

    End Sub

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        yourlogo.Show()
        CheckUpdata("http://127.0.0.1/updateinfo.txt")

    End Sub

    Private Sub WebClient1_DownloadFileCompleted(ByVal sender As System.Object, ByVal e As System.ComponentModel.AsyncCompletedEventArgs) Handles WebClient1.DownloadFileCompleted

        ProgressBar1.Value = ProgressBar1.Maximum
        Dim version As New TextBox
        version.Text = My.Computer.FileSystem.ReadAllText("updateinfo.ver")
        Label2.Text = version.Text

        Dim new_ver As Double = version.Text
        Dim cur_ver As Double = Application.ProductVersion
        If new_ver > cur_ver Then
            On Error Resume Next
            If My.Computer.FileSystem.FileExists("updateinfo.ver") Then
                My.Computer.FileSystem.DeleteFile("updateinfo.ver")
            End If
            MsgBox("New version detected!", MsgBoxStyle.Information, "Updater")
            frmDLMain.Show()
            Me.Close()
        Else

            If My.Computer.FileSystem.FileExists("updateinfo.ver") Then
                My.Computer.FileSystem.DeleteFile("updateinfo.ver")
            End If
            yourlogo.Close()
            yourapp.Show()
            Me.Close()
        End If
    End Sub

The last set of codes.
This code bascially detects if a file is existed in the same directory and if it does not , it will download from a webpage.

If My.Computer.FileSystem.FileExists("Patcher.exe") Then
                   frmMain.show()
                   Else
                [download the file from webpage, which the code above, the first set of codes, so you don't need to convert again.]
            End If

I will really apreciate it if you guys are willing to help me . I am seriously sick of this thing ..
Thanks in advance.

Try this
Here is the last one done for you

if (My.Computer.FileSystem.FileExists("Patcher.exe")) {
	frmMain.show();
} else {
	// [download the file from webpage, which the code above, the first set of codes, so you don't need to convert again.]
}

VB.Net and C# are nearly identical (they use the same framework). There's mostly just a few syntactial differences between the two. Instead of posting entire code blocks and expecting us to kindly convert it for you, try and learn these syntax differences and post any specific problems you might be having.
