C# Reflection Invoke - Object of Type 'XXX' Cannot Be Converted to type 'System.Object[]'
c#, reflection
Solution
You are passing the wrong arguments to the method. It wants an object[] and you are giving a simpe object. This is how to fix it:
object[] arr = new object[] { new object[] { input } };
The 'outer' object[] is the parameter for Invoke, the 'inner' array is the parameter for your method.
Problem
I have created an instance called `input` that is of type: ``` public class TestInput { public int TesTInt { get; set; } } ``` I use this in this function: ``` public static class TestClass { public static string TestFunction() { var testInput = new TestInput(); string res = ServicesManager.Execute<string>((object) testInput); return res; } } ``` The `Execute` function is here: ``` public static OUT Execute<OUT>(object input) where OUT : class { var method = //getting method by reflection object[] arr = new object[] { input }; return method.Invoke(null, arr) as OUT; //Error is triggered here } ``` The method that I invoke is this one: ``` public static string TestFunctionProxy(object[] input) { var serviceInput = input[0] as TestInput; //rest of code } ``` I received the error in the title. (XXX - "TestInput" type) What's happening and what is causing this error? Note: `method` is static so no instance is required for the first parameter. Please correct me if I'm wrong. Any help is appreciated. EDIT: Updated the question with some more code for a complete example.
