Binary operators overloading

Binary operators overloading there are two arguments
the general form of operator function for binary operators is as follows.
One of the parameters has to be of a type in which the operator is declared. They include +, -, *, /, %, &, |, ^, <<, >>, ==, !=, >, <, >=, and <=.
public static return_type operator op (Type1 t1, Type2 t2)
{
//Statements
}

Example

public static biop operator +(biop ob1,biop ob2)
{
biop b=new biop();
b.real=ob1.real+ob2.real;
b.im=ob1.im+ob2.im;
return b;
}


Example program in C# Console application

using System;
class biop
{
public int real,im;
public biop(){}
public biop(int r,int i)
{
real=r;
im=i;
}
public void disp(){Console.WriteLine(real+"+i"+im);}
public static biop operator +(biop ob1,biop ob2)
{
biop b=new biop();
b.real=ob1.real+ob2.real;
b.im=ob1.im+ob2.im;
return b;
}
}
class binaryoperator
{
public static void Main(string[] args)
{
biop b1=new biop(5,5);
b1.disp();
biop b2=new biop(2,2);
b2.disp();
biop b3=b1+b2;
b3.disp();
}
}
