public class Example
{
public static void Main()
{
try {
// Outer block to handle any unexpected exceptions.
try {
string s = "This";
s = s.Insert(2, "is ");
// Throw an OutOfMemoryException exception.
throw new OutOfMemoryException();
}
catch (ArgumentException) {
Console.WriteLine("ArgumentException in String.Insert");
