如何使一个非常简单的异步方法调用在vb.net

当我调用该方法时,最终会在网站上等待子程序完成.然而,即使网站超时,例行程序最终完成任务,所有的目录都应该是最终的.

我想防止超时,所以我只想异步地调用Sub.我不需要(甚至想要)和回调/确认它成功运行.

那么,如何使用VB.net在网站内异步调用我的方法？

如果你需要一些代码：

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

Protected Sub DoAsyncWork()
        Dim ID As String = ParentAccountID
        Dim ParentDirectory As String = ConfigurationManager.AppSettings("AcctDataDirectory")
        Dim account As New Account()
        Dim accts As IEnumerable(Of Account) = account.GetAccounts(ID)

        For Each f As String In My.Computer.FileSystem.GetFiles(ParentDirectory)
            If f.EndsWith(".txt") Then
                Dim LastSlashIndex As Integer = f.LastIndexOf("")
                Dim newFilePath As String = f.Insert(LastSlashIndex,"Templates")
                My.Computer.FileSystem.CopyFile(f,newFilePath)
            End If
        Next

        For Each acct As Account In accts
            If acct.ID <> ID Then
                Dim ChildDirectory As String = ConfigurationManager.AppSettings("AcctDataDirectory") & acct.ID
                If My.Computer.FileSystem.DirectoryExists(ChildDirectory) = False Then
                    IO.Directory.CreateDirectory(ChildDirectory)
                End If
                My.Computer.FileSystem.DeleteDirectory(ChildDirectory,FileIO.DeleteDirectoryOption.DeleteAllContents)
                My.Computer.FileSystem.CopyDirectory(ParentDirectory,ChildDirectory,True)
            Else
            End If
        Next
End Sub
