Question

mydll.dll

namespace mydll
{
    public class MyClass {
        public static int Add(int x, int y)
        {
            return x +y;
        }
    }
}

In another project how can I import MyClass or just Add function?

I want to add with DllImport,

[DllImport(“mydll.dll”, CharSet =
CharSet.Auto) ] public static extern
…….

how can I do that?

Answer 1

You can use Reflection to load assembly at runtime.

Here a piece of code you can use :

Assembly myAssembly ;
myAssembly = Assembly.LoadFile("myDll.dll");

object o;
Type myType =  myAssembly.GetType("<assembly>.<class>");
o = Activator.CreateInstance(myType);

Here you can find a good tutorial.
