You can make use of Action Delegate to achieve your requirement like below

First Create a method like below in your page

 Public Sub DisplayMessage()
        MsgBox("test")
    End Sub

now assign this method to Delegate and then call Run method in task to execute it

  Dim t As Action = New Action(AddressOf DisplayMessage)

        'Execute the method
        Task.Run(t)

Hi fazioliamboina

As a2h suggested, you could use Action delegate. Action delegate didn’t return a value.

The usage of it as below:

 protected void Page_Load(object sender, EventArgs e)
        {
            Action<string> t = ShowWindowsMessage;
            // Execute the method
            t("message");
        }
          void ShowWindowsMessage(string message)
        {
            TextBox1.Text = message;
        }

Output:
