Migrating Handles from VB.NET to C#

Question

Hi, I'm migrating some code from VB.NET to C# (3.5).

I find structurs like:

Public Event DataLoaded(ByVal sender As Object, ByVal e As EventArgs)

Protected Sub Mag_Button_Load_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Mag_Button_Load.Click
[..]
        RaiseEvent DataLoaded(Me, EventArgs.Empty)
End Sub
[..]

'Other Class
Private Sub LoadData(ByVal sender As Object, ByVal e As System.EventArgs) Handles oData.DataLoaded
[..]
End Sub

What is the most streight-forward to translate such behavour in C#? Thanks

I recommend using the Telerik Code Converter as a start.

C# does not have that easy automatic attaching of event handlers by means of the "Handles" keyword like VB.NET does.

//EventHandler declaration
public event EventHandler  DataLoaded;
protected void Mag_Button_Load_Click(object sender, EventArgs e)
{

    //Raise Event
    if (DataLoaded != null) {
     DataLoaded(this, EventArgs.Empty);
    }
}

Also, You need to assign your event handlers to the objects like this:

Button1.Click += Button1_Click;

protected void Button1_Click(object sender, EventArgs e)
{
  //do something.
}

However C# does have the succinct ability of doing this as well:

Button1.Click += (sender, e)=>
{
    //do something
}
