C# provides a large set of operators,
which are symbols that specify which operations to perform in an expression.
It is a symbol that tells the compiler to
perform specific mathematical or logical manipulations. Below are different types of operators in C#.
Assignment operator

=

Additive


Multiplicative


Relational and type
testing


Equality


Conditional AND


Conditional OR


Conditional


Nullcoalescing

1)Let us start with assignment operator
If we have variable
I and we want to assign value 10 to this, we can use assignment operator
int i = 10;
if
we want to assign true or false value to a bool type variable,we can use
assignment operator.
bool check = true;
2) Additive
If we want
to add 2 numbers, we will use Additive operator +
int i = 10;
int j = 20;
int result=i+j;
Console.WriteLine("result
is {0} ",result);
Console.ReadLine();
Please visit Operators in C# video tutorials.
3)Multiplicative
If we divide
2 numbers,we get quotient and remainder.
if we use /,we get quotient.
int Numerator = 20;
int Denominator = 5;
int result = Numerator / Denominator;
Console.WriteLine("result
is {0} ",result);
Console.ReadLine();
result=4
if we use %,we get remainder.
int Numerator = 21;
int Denominator = 5;
int result = Numerator % Denominator;
Console.WriteLine("result
is {0} ",result);
Console.ReadLine();
result=1
4) Relational
If we want
to check 2 numbers which is greater or smaller, we have to use Relational operator
int x = 50;
int y = 20;
if (x > y)
{
Console.WriteLine("x
is greater than y");
}
Console.ReadLine();
5) Equality
If we want
to compare 2 numbers, we have to use Equality operator
int x = 20;
int y = 20;
if (x == y)
{
Console.WriteLine("x
is equal to y");
}
Console.ReadLine();
if we want to check that x is not equal to y,we have to use !=
int x = 20;
int y = 25;
if (x != y)
{
Console.WriteLine("x
is not equal to y");
}
Console.ReadLine();
6) Conditional AND OR
If we have to
check 2 conditions we can use && operator
int x = 50;
int y = 20;
if (x == 50 && y==20)
{
Console.WriteLine("both
conditions are true");
}
Console.ReadLine();
If we want
to satisfy one condition between two , we use or operator
int x = 50;
int y = 21;
if (x == 50  y==20)
{
Console.WriteLine("one
of two condition is true ");
}
Console.ReadLine();
