Executing C# Assembly in Memory Using Assembly.Load()

Here is a simple code to load a C# assembly (exe or dll) in memory from C#/
using System;
using System.IO;
using System.Reflection;
namespace AssemblyLoader
class Program
static void Main(string[] args)
Byte[] fileBytes = File.ReadAllBytes("C:\\Tools\\JustACommandWithArgs.exe");
string[] fileArgs = { "arg1", "arg2", "argX" };
ExecuteAssembly(fileBytes, fileArgs);
public static void ExecuteAssembly(Byte[] assemblyBytes, string[] param)
// Load the assembly
Assembly assembly = Assembly.Load(assemblyBytes);
// Find the Entrypoint or "Main" method
MethodInfo method = assembly.EntryPoint;
// Get the parameters
object[] parameters = new[] { param };
// Invoke the method with its parameters
object execute = method.Invoke(null, parameters);
