We can use reflection to call a class and its methods and properties using method and property names. Here is an example where we call a method using the method name.

Before you use this approach, you must import System.Reflection namespace.

using System.Reflection;

Here we create a instance of the class and gets a method instance using the GetMethod method. The Invoke method executes the method.

classdemo c1 = new classdemo();
MethodInfo mi = typeof(classdemo).GetMethod("functionname_in_string_format");
mi.Invoke(c1, null);
