Calling the base constructor in C#

.net, c#, constructor, inheritance

Solution

Modify your constructor to the following so that it calls the base class constructor properly:

public class MyExceptionClass : Exception
{
    public MyExceptionClass(string message, string extrainfo) : base(message)
    {
        //other stuff here
    }
}

Note that a constructor is not something that you can call anytime within a method. That's the reason you're getting errors in your call in the constructor body.

Problem

If I inherit from a base class and want to pass something from the constructor of the inherited class to the constructor of the base class, how do I do that? For example, if I inherit from the Exception class I want to do something like this: ``` class MyExceptionClass : Exception { public MyExceptionClass(string message, string extraInfo) { //This is where it's all falling apart base(message); } } ``` Basically what I want is to be able to pass the string message to the base Exception class.
