C#可以实现DLL库的动态调用

Assembly assmebly  =  Assembly.LoadFile( @" C:WindowsApplication2005-09-30.dll " );
Type t  =  assmebly.GetType( " WindowsApplication2005_09_30.Class1 " );
object  obj  =  Activator.CreateInstance(t, null );
MethodInfo method  =  t.GetMethod( " Test01 " );
int  i  =  ( int )method.Invoke(obj, new   object [ 1 ] {10} );
namespace  WindowsApplication2005_09_30
{
public class Class1
{
public int Test01(int i)
{
return i*10;
}
}
