Hi,
I want to use a dll which is created in vs2005 into my current vs2008 project.I succesfully added dll (vs2005) into vs2008 project.But when i try to access the class which is in vs2005 dll,it is throwing an exception "Assembly cannot be loaded version=1.0.0.0 'system.filenotfoundexception'".
I tried the following things....
1)I added vs2005 prjt to vs2008 prjt.
2)I added the dll to vs2008 project.
3)i tired reflection concept to load the dll dynamically.

But none of things worked for me.Please help me..

There is no reason on earth for you to have this issue. I suggest you step in to your dll and find out what line is trying to access a file. Better yet, if you catch this exception and view the stack trace, you can find out where it happened, and perhaps even what file it is looking for, there. It's trying to load a file and it can't, I doubt that has to do with the version of .NET.

Hi,
It is trying to cal a method in a class which is in the dll(vs2005).But it raising an exception"System.Filenotfoundexception"

Yes, I see that. So, step in to the code, or catch the exception, to try to work out what file it is.

Well one thing you can do is to load the assembly from a particular location and then call:

C#

Assembly a = Assembly.LoadFile(@"C:\AClassLibrary\bin\Debug\AClassLibrary.dll");

I have explained the way to invoke methods from a dynamically loaded assembly here : http://tarundotnet.wordpress.com/2011/06/30/how-to-dynamically-load-assemblies/[^]

Do let me know if it doesn't work.
Good luck. :thumbsup:

Update 2:
Ok, so you are not able to find the method to invoke. Well then you can get all the methods like this:

C#

Assembly a = Assembly.LoadFile(@"C:\AClassLibrary\bin\Debug\AClassLibrary.dll");
// Get the Type of the class.
Type clsType = a.GetType("AClassLibrary.AClass");
// Get all the methods of the class.
MethodInfo[] methods = clsType.GetMethods();

So what now you will get an array of methods. Search in that array what is the exact method that you are looking for.
Hope this helps.
