Can we throw exception from catch block ?..

Answer / nilesh

Yes. A throw statement can be used in the catch block to re-
throw the exception, which has been caught by the catch
statement. For example:

catch (InvalidCastException e)
{
throw (e); // Rethrowing exception e
}

Answer / arjun

The exceptions, which we caught inside a catch block, can
re-throw to a higher context by using the keyword throw
inside the catch block. The following program shows how to
do this.

//C#: Exception Handling: Handling all exceptions
using System;
class MyClass
{
public void Method()
{
try
{
int x = 0;
int sum = 100/x;
}
catch(DivideByZeroException e)
{
throw;
}
}
}
class MyClient
{
public static void Main()
{
MyClass mc = new MyClass();
try
{
mc.Method();
}
catch(Exception e)
{
Console.WriteLine("Exception caught here" );
}
Console.WriteLine("LAST STATEMENT");
}
}
