NullReferenceException
This exception is thrown when you try to dereference a null pointer (for example, accessing an instance field on an object reference that currently points to no instance).
public class NullReferenceException : SystemException { // Public Constructors public method NullReferenceException(); public method NullReferenceException(string message); public method NullReferenceException(string message, Exception innerException); // Protected Constructors protected method NullReferenceException( System.Runtime.Serialization.SerializationInfo info, System.Runtime.Serialization.StreamingContext context); }
