The **`this` keyword** in C# is a pointer reference to the current instance or object of a struct or class.

`this` is the preferred way to refer to members or parameters of classes or structs whose names may not be unique in a given context, and may only be used with non-static class or struct methods.

#  How to use `this` with member variables or functions

You can use the `this` keyword to access member variables or functions within a class. This is also useful when the parameter names are the same as the member variables, as `this` helps to distinguish between them.


When you access members within constructors, you must put the `this` keyword before the function or member that you are accessing.

##   
## Code
Below is an example of how to use the `this` keyword with a member variable.


using System;

class Person {
  private string name = ""; 
  private int age = 0;

  public Person(string name, int age) {
    this.name = name;
    this.age = age;
  }

  public void print() {
    Console.WriteLine("Name: " + getName());
    Console.WriteLine("Age: " + getAge());
  }

  public string getName() { return name; }
  public int getAge() { return age; }
}

class HelloWorld
{
    static void Main()
    {
      Person person = new Person("John", 30);
      person.print();
    }
}

#    
## Explanation
In the example above, you can see that we use the `this` keyword within the constructor and the `print()` method to resolve ambiguity between the parameters and member variables of the same name.

> `this` can also be used to pass the current object to another method.
