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.
Note that you can use static methods within the call to the base constructor.
class MyExceptionClass : Exception
{
public MyExceptionClass(string message, string extraInfo) :
base(ModifyMessage(message, extraInfo))
{
}
private static string ModifyMessage(string message, string extraInfo)
{
Trace.WriteLine(“message was ” + message);
return message.ToLowerInvariant() + Environment.NewLine + extraInfo;
}
}
