Class access problem
I have a class library which is name ClassLib. And that lib has two folders (MedulaClasses and ParserClasses). MedulaClasses has a class which is name SGKDuyurulari.cs. And ParserClasses has a class which is name GeneralParser.cs. I write
SGKDuyurulari sd = new SGKDuyurulari()
in GeneralParser. but i have a runtime error. but error says just, The type initializer for 'ClassLib.MedulaClasses.SGKDuyurulari' threw an exception. and inner exception is "Object reference not set to an instance o开发者_开发问答f an object.". I dont understand anythig. how can i access class from different folders.
Thanks for your help.
The exception you are getting ("type initializer") is associated with a static member. Do you have any static fields or a static constructor in SGKDuyurulari? Something like:
private static readonly string someString = CreateSomeString(); // whoops, throws exception at runtime.
or:
static SGKDuyurulari()
{
// Do something in here that throws an exception at runtime.
}
These are both called the first time anything in your application accesses the type in any way.
To reference an object in another namespace, just add a using:
using ClassLib.MediaClasses;
But that isn't the error. The error is that code in the constructor is throwing an exception for some reason. Look in the constructor and see what is going on; if you post code, I can help you further.
check the constructor for SGKDuyurulari, is it using an uninitialized object?
[sometimes the folder structure affects the namespace, but if it compiles then that's not the problem]
