Can C# Invoke Functions Dynamically from Strings Using Reflection?

Calling functions through strings in C#

PHP can easily call functions through strings. So, can C# implement this function?

Answer: Reflection

Yes, reflection allows you to dynamically execute methods via strings. Here’s how:

Type thisType = this.GetType();
MethodInfo theMethod = thisType.GetMethod(TheCommandString);
theMethod.Invoke(this, userParameters);

This code works because it retrieves the method's MethodInfo using the string representation of the method name.

Non-public methods

If you need to call non-public methods, use BindingFlags:

MethodInfo theMethod = thisType
    .GetMethod(TheCommandString, BindingFlags.NonPublic | BindingFlags.Instance);
theMethod.Invoke(this, userParameters);

This specifies that the method is non-public and instance-specific.
