How to load assembly into memory and execute it

This is what im doing:

byte[] bytes = File.ReadAllBytes(@Application.StartupPath+"/UpdateMainProgaramApp.exe");
Assembly assembly = Assembly.Load(bytes);
// load the assemly

//Assembly assembly = Assembly.LoadFrom(AssemblyName);

// Walk through each type in the assembly looking for our class
MethodInfo method = assembly.EntryPoint;
if (method != null)
{
    // create an istance of the Startup form Main method
    object o = assembly.CreateInstance(method.Name);
    // invoke the application starting point
    try
    {
        method.Invoke(o, null);
    }
    catch (TargetInvocationException e)
    {
        Console.WriteLine(e.ToString());
    }
}

The problem is that it throws that TargetInvocationException - it finds that the method is main, but it thr开发者_如何学JAVAows this exception since on this line:

object o = assembly.CreateInstance(method.Name);

o is remaining null. So I dug a bit into that stacktrace and the actual error is this:

InnerException = {"SetCompatibleTextRenderingDefault should be called before creating firstfirst IWin32Window object in the program"} (this is my translation since it gives me the stacktrace in half hebrew half english since my windows is in hebrew.)

What am i doing wrong?

The entry point method is static, so it should be invoked using a null value for the "instance" parameter. Try replacing everything after your Assembly.Load line with the following:

assembly.EntryPoint.Invoke(null, new object[0]);

If the entry point method is not public, you should use the Invoke overload that allows you to specify BindingFlags.

if you check any WinForm application Program.cs file you'll see there always these 2 lines

Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);

you need to call as well them in your assembly. At least this is what your exception says.

How about calling it in it's own process?
