List a program’s loaded assemblies in C#

The key to this example is the following ListAssemblies method.

// List the assemblies.
private void ListAssemblies()
{
    lblNumAssemblies.Text = "";
    lstAssemblies.Items.Clear();
    Cursor = Cursors.WaitCursor;
    Refresh();

    foreach (Assembly assembly in
        AppDomain.CurrentDomain.GetAssemblies())
    {
        lstAssemblies.Items.Add(assembly.GetName().Name);
    }

    // Display the number of assemblies.
    lblNumAssemblies.Text =
        lstAssemblies.Items.Count.ToString() + " assemblies";
    Cursor = Cursors.Default;
}

To list the assemblies that the program has loaded, the code calls AppDomain.CurrentDomain.GetAssemblies and loops over the Assembly objects that it returns. The program calls each object’s GetName method to get an AssemblyName object for it. It displays the value of that object’s Name property in the list box.
