Reflection: How to Invoke Method with parameters

I am trying to invoke a method via reflection with parameters and I get: object does not match target type If I invoke a method without parameters, it works fine. Based on the following code if I call the method `Test("TestNoParameters")`, it works fine. However if I call `Test("Run")`, I get an exception. Is something wrong with my code? My initial purpose was to pass an array of objects e.g. `public void Run(object[] options)` but this did not work and I tried something simpler e.g. string without success. ``` // Assembly1.dll namespace TestAssembly { public class Main { public void Run(string parameters) { // Do something... } public void TestNoParameters() { // Do something... } } } // Executing Assembly.exe public class TestReflection { public void Test(string methodName) { Assembly assembly = Assembly.LoadFile("...Assembly1.dll"); Type type = assembly.GetType("TestAssembly.Main"); if (type != null) { MethodInfo methodInfo = type.GetMethod(methodName); if (methodInfo != null) { object result = null; ParameterInfo[] parameters = methodInfo.GetParameters(); object classInstance = Activator.CreateInstance(type, null); if (parameters.Length == 0) { // This works fine result = methodInfo.Invoke(classInstance, null); } else { object[] parametersArray = new object[] { "Hello" }; // The invoke does NOT work; // it throws "Object does not match target type" result = methodInfo.Invoke(methodInfo, parametersArray); } } } } } ```
