this keyword in c#

"This" keyword is used to refer to the current object of the class. It is used to resolve conflicts between variables having the same names and to pass the current object as a parameter. You cannot use this keyword with static variables and methods.

Example 1:

class person
{
private string name;
public person(string name)
{
//use the "this" keyword to set the local variable
this.name = name;
}
public void introduceyourself()
{
Console.WriteLine("Hello, My name is " + this.name);
Console.ReadKey();
}
}

class Program
{
static void Main(string[] args)
{
person personobj = new person("TEXVN");
personobj.introduceyourself();
}
}

Output:-
Hello, My name is TEXVN

Example 2:

class myclass
{
private int num;
public myclass(int num)
{
//Use the "this" keyword to disambiguate between the parameter

and the class feild
this.num = num;
}
public void displaynum()
{
//Use the "This" keyword to access the class number
Console.WriteLine("Number Value: " + this.num);
Console.ReadKey();
}
}

class program
{
static void Main(string[] args)
{
myclass myclassobj = new myclass(60);
myclassobj.displaynum();
}
}
