What is the meaning of “this” in C#

Question

Could anyone please explain the meaning \"this\" in C#?

Such as:

// complex.cs
using System;

public struct Complex 
{
   public int real;
   public          


        

Answer 1

this is a variable which represents the current instance of a class. For example

class SampleClass {
public SampleClass(someclass obj) {
obj.sample = this;
}
}

In this example, this is used to set the "sample" property on someclass obj, to the current instance of SampleClass.
