System.TypeInitializationException fix was unhandled

Question

What does it mean when MS Visual Studio 2005 displays this message?

"The type initializer for 'RMDC.clsVariables' threw an exception."

The error log is as follows

System.TypeInitializationException was unhandled

Answer 1

Well, that means that he said something in the type initializer for RMDC.clsVariables(which is an unconventional name, by the way) has gone.

It can be a static variable initializer:

static int foo = GetInitialValueForFoo();

or static constructor:

static clsVariables
{
    DoSomething();
}

Be that as it may, he failed, leaving your type unsuitable.

If you run the code in the debugger, it should fail as soon as an exception is thrown, which will simplify the work on what happens.
