Null Pointer Exception in C#

CsharpProgrammingServer Side Programming

NullReferenceException is a C# version of NullPointerException. To handle and catch it in C#, use try-catch.

The below example shows that a variable is set to null and when we try to print it, it throws an exception that gets caught in the catch −

Try {
   a = null;
}catch (NullPointerException ex) {
   Console.WriteLine("Variable is Null!");

The above will allow the exception to be caught and use catch for it.
