C# Reflection How-to?

While this may not help you, it may help others. Here is a simplified example of reflection:

using System; using System.Reflection; namespace TeamActivity { class Program { static void Main(string[] args) { // Dynamically load assembly from the provided DLL file. Assembly CustomerAssembly = Assembly.LoadFrom( "BasicCalculations.dll" ); // Get a Type from the Assembly Type runtimeType = CustomerAssembly.GetType( "BasicCalcuation.BasicCalc" ); // Get all methods from the Type. MethodInfo[] methods = runtimeType.GetMethods(); // Loop through all discovered methods. foreach ( MethodInfo method in methods ) { Console.WriteLine( "Method name: " + method.Name ); // Create an array of parameters from this method. ParameterInfo[] parameters = method.GetParameters(); // Loop through every parameter. foreach ( ParameterInfo paramInfo in parameters ) { Console.WriteLine( "\tParamter name: " + paramInfo.Name ); Console.WriteLine( "\tParamter type: " + paramInfo.ParameterType ); } Console.WriteLine( "\tMethod return parameter: " + method.ReturnParameter ); Console.WriteLine( "\tMethod return type: " + method.ReturnType ); Console.WriteLine("\n"); } // Invoke the Type that we got from the DLL. object Tobj = Activator.CreateInstance( runtimeType ); // Create an array of numbers to pass to a method from that invokation. object[] inNums = new object[] { 2, 4 }; // Invoke the 'Add' method from that Type invokation and store the return value. int outNum = (int)runtimeType.InvokeMember( "Add", BindingFlags.InvokeMethod, null, Tobj, inNums ); // Display the return value. Console.WriteLine( "Output from 'Add': " + outNum ); Console.WriteLine( "\nPress any key to exit." ); Console.ReadKey(); } } }
