Creating and Throwing Exceptions (C# Programming Guide) Visual Studio 2015 https://msdn.microsoft.com/en-us/library/ms173163.aspx Other Versions Visual Studio 2013 Visual Studio 2012 Visual Studio 2010 Visual Studio 2008 Visual Studio 2005 Exceptions are used to indicate that an error has occurred while running the program. Exception objects that describe an error are created and then thrown with the throw keyword. The runtime then searches for the most compatible exception handler.Programmers should throw exceptions when one or more of the following conditions are true:The method cannot complete its defined functionality.For example, if a parameter to a method has an invalid value: C# Copy static void CopyObject(SampleClass original) { if (original == null) { throw new System.ArgumentException("Parameter cannot be null", "original"); } } An inappropriate call to an object is made, based on the object state.One example might be trying to write to a read-only file. In cases where an object state does not allow an operation, throw an instance of InvalidOperationException or an object based on a derivation of this class. This is an example of a method that throws an InvalidOperationException object: C# Copy class ProgramLog { System.IO.FileStream

I am thinking something similar you have for example in Oracle PL/SQL where you can simply write raise_application_error(-20001, 'An arbitary error message'); at any place. c# asp.net exception share|improve this question edited May 1 '15 at 20:31 Dan Beaulieu 7,30364672 asked May 1 '15 at 20:13 Wernfried Domscheit 9,67821332 You can add custom properties to a custom exception class, so couldn't you just make one custom exception class, then add an Enum for the "type" of exception? –mellamokb May 1 '15 at 20:14 6 If throw new Exception("An arbitary error message"); won't work for you, it might be a good idea to extend a question to explain why. –DK.
