Fusion of assembly example

Posted By:Jean Paul       Posted Date: September 30, 2010    Points: 10    Category: Javascript    URL: http://www.dotnetspark.com  

This example shows how to load an assembly dynamically into the current domain and invoke a method.
 

// Create a ClassLibrary project and add the following class into it
// Add reference to System.Windows.Forms too
// Copy the dll to folder c:\temp

    public class Utility
    {
        public void ShowMessage()
        {
            MessageBox.Show("Hello from Utility!");
        }
    }

// Create a new Windows Application and add the following code to the form load event

            Assembly assembly = Assembly.LoadFile(@"c:\temp\ClassLibrary1.dll");
            Type type = assembly.GetType("ClassLibrary1.Utility");

            if (type != null)
            {
                object instance = Activator.CreateInstance(type);
                type.GetMethod("ShowMessage").Invoke(instance, null);
            }
            else
                MessageBox.Show("Unable to find type!");
