VB.Net程序应该自动更新

保留单独的更新程序,然后当您想要更新旧程序时,让更新程序关闭旧程序,然后下载新版本的应用程序.例如,

更新程序,

Private Sub Form1_Load(sender As Object,e As EventArgs) Handles Me.Load
    Do While True
        Dim client As New Net.WebClient
        Dim newVersion As String = client.DownloadString("http://www.myWebsite.com/updates/latestVersion.txt")
        If newVersion <> IO.File.ReadAllText("Your programs file location") Then
            For Each p As Process In Process.GetProcesses
                If p.ProcessName = "your program's process name" Then 'If you don't know what your program's process name is,simply run your program,run windows task manager,select 'processes' tab,scroll down untill you find your programs name.
                    p.Kill()
                End If
            Next
            IO.File.Delete("old program file location")
            client.DownloadFile("http://www.myWebsite.com/updates/12.05.2013.exe","where ever you want to download your new program to (file location)")
            client.Dispose()
        End If
        Threading.Thread.Sleep(300000) 'freeze thread for 5 mins...
    Loop
End Sub
