How Can I Dynamically Invoke C# Functions Using Reflection?

C# dynamic function call: the solution of reflection technology

is similar to the function of calling functions through strings using $function_name() in PHP, which has always been the focus of C# developers. Although C# cannot call functions directly through strings, reflection technology provides a powerful alternative.

Reflection-based function call

C#’s reflection mechanism allows type information to be inspected and manipulated at runtime. Using reflection we can dynamically call methods by name. The specific method is as follows:

Type thisType = this.GetType(); // 获取当前对象的类型
MethodInfo theMethod = thisType.GetMethod(TheCommandString); // 按名称获取方法信息
theMethod.Invoke(this, userParameters); // 调用方法

In the code, "TheCommandString" represents the name of the method to be called, and "userParameters" is the parameter array passed to the method. It should be noted that the called method must have a public access modifier, otherwise additional parameters such as BindingFlags.NonPublic | BindingFlags.Instance need to be used to bypass access restrictions.
