Raise Event in c#

Hi, I have this code from vb that call the method test from raising an event. I want to convert it in c# but the converted code from converter are not working, I search around and I have no luck of finding a simple one like in vb.

	Public Event Connected(ByVal msg As String)

    Sub test(ByVal msg As String) Handles Me.Connected
        TextBox1.Text = msg
    End Sub

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        RaiseEvent Connected("It works!")
    End Sub
