How to: Use Lambda Expressions Outside LINQ (C# Programming Guide)

Lambda expressions are not limited to LINQ queries. You can use them anywhere a delegate value is expected, that is, wherever an anonymous method can be used. The following example shows how to use a lambda expression in a Windows Forms event handler. Notice that the types of the inputs (Object and MouseEventArgs) are inferred by the compiler and do not have to be explicitly given in the lambda input parameters.

public partial class Form1 : Form
    public Form1()
        // Use a lambda expression to define an event handler.
       this.Click += (s, e) => { MessageBox.Show(((MouseEventArgs)e).Location.ToString());};
