MethodInfo

MethodInfo is a class in the .NET reflection API that provides information about a method and allows invoking it. It is part of the System.Reflection namespace. A MethodInfo object represents a method, constructor, or delegate. It can be obtained using various reflection methods, such as `Type.GetMethod()` or `Type.GetMethods()`.

Key properties of MethodInfo include its name, return type, parameter types, and attributes. It also provides information about the declaring type and whether the method is static or an instance method. The `Invoke()` method is used to execute the represented method. This method takes an object instance (for instance methods) and an array of arguments as parameters. The return value of the `Invoke()` method is the value returned by the invoked method.

MethodInfo is commonly used in scenarios where code needs to dynamically discover and execute methods at runtime. This includes frameworks for serialization, dependency injection, and object mapping, as well as tools for debugging and testing. It allows for a high degree of flexibility and extensibility in .NET applications by enabling code to operate on methods without knowing their specific details at compile time. Using reflection, including MethodInfo, can have performance implications due to the overhead involved, so it is generally recommended to use it judiciously.
