You can use the AlertDialog.Buider class from within an Activity.

new AlertDialog.Builder(this)
    .SetPositiveButton("Yes", (sender, args) =>
    {
        // User pressed yes
    })
    .SetNegativeButton("No", (sender, args) =>
    {
        // User pressed no 
    })
    .SetMessage("An error happened!")
    .SetTitle("Error")
    .Show();

Thanks. It works. But How I can make it looks better like the MessageBox in Windows phone ? The MessageBox has Height, width and background color. – MilkBottle May 21 '13 at 01:43

See the xml from [this](http://stackoverflow.com/a/13763132/1411687) answer and use the constructor from [this](http://stackoverflow.com/a/3119581/1411687) one. Note that prior to API level 11 you must use a `ContextThemeWrapper` to theme the dialog as the newer constructor isn't available. – Alex Wiese May 21 '13 at 01:53

Try this:

public void ShowAlert (string str)
        {
            AlertDialog.Builder alert = new AlertDialog.Builder (this);
            alert.SetTitle (str);
            alert.SetPositiveButton ("OK", (senderAlert, args) => {
                // write your own set of instructions
                });

            //run the alert in UI thread to display in the screen
            RunOnUiThread (() => {
                alert.Show ();
            });
        }
