Question

I would like to know if there is a way in c# to execute a method, if we have only it’s name in a string ?

string methodname="method"
this.RunMethod(methodname)

Something like that ?

Thanks 🙂

You can create a generic method to invoke methods by their name on any instance you want this way:

public void RunMethodOn(object obj, String methodName,params Object[] args)
        {
            if(obj != null)
            {
                System.Reflection.MethodInfo method = null;
                method = obj.GetType().GetMethod(methodName);
                if (method != null)
                    method.Invoke(obj, args);
            }
        }

And the use it to call a method on your own instance as you ask:

public void RunMethod(String methodName,params Object[] args)
            {
                   ExecuteOn(this, methodName, args);
            }
