Hello
I'm new to C# and wonder if it is possible as it is possible in C++ to
dynamically load a DLL and use it in C#.
The dll is written in C++ and has the following export:
int test(void);
and the code resides in test.dll
I want a C# application that when I press Button1, it should
dynamically load test.dll and its 'test' function and call it and get
its return value.
Is this possible in C#? If so, how?

I guess your dll is unmanaged. Write a managed wrapper in C++ and use this in C#.

Hi Bob,
May be it is a stupid question, but I am new to .Net and I am wondering if you can please help me.
How can you dynamically load a component in c#. Imean I understand that you can do the new and can have an instance of a component but for that it is also required to use "using component class".
What I want to achieve is to read teh name of component from some out side file and then can instantiate it.
Regards,
Rawal. | |

Do you want to instanciate a managed class or a set of exported
functions from a DLL?
Cheers,
Stu

Hi,
You can dynamically load a managed component (.dll) by using the
components under System.Reflection namespace, like
"System.Reflection.Assembly". You can load the dll by using
System.Reflection.Assembly.Load(..)
System.Reflection.Assembly.LoadFile(string FileName)
System.Reflection.Assembly.LoadFrom(string FilePath)
methods. If you do not have managed dll, you have to wrap it and load
the wrapper. After loading you can use the loaded component by using
the other classes under same namespace(Sys.Ref).
Regards,
Dincer
