How to raise event using addHandler

Question

I am comfortable with Vb.Net events and handlers. Can anybody will help me with how to create event handlers in c#, and raise events.

Answer 1

Developers who know only C#, or only VB.Net, may not know that this is one of the larger differences between VB.NET and C#.

I will shamelesssly copy this nice explanation of VB events: VB uses a declarative syntax for attaching events. The Handles clause appears on the code that will handle the event. When appropriate, multiple methods can handle the same event, and multiple events can be handled by the same method. Use of the Handles clause relies on the WithEvents modifier appearing on the declaration of the underlying variable such as a button. You can also attach property handlers using the AddHandler keyword, and remove them with RemoveHandler. For example

Friend WithEvents TextBox1 As System.Windows.Forms.TextBox   

Private Sub TextBox1_Leave(ByVal sender As System.Object, _
  ByVal e As System.EventArgs) Handles TextBox1.Leave
  'Do Stuff '
End Sub

In C# you can't use the declarative syntax. You use += which is overloaded to act like the VB.Net AddHandler. Here's an example shamelessly stolen from tster's answer:

public MyClass()
{
    InitializeComponent();
    textBox1.Leave += new EventHandler(testBox1_Leave);
}

void testBox1_Leave(object sender, EventArgs e)
{
  //Do Stuff
}
