How to use C# if else statements

This example shows you How to use c# if else statements. If...else statements make it easy check the condition in c# programming.

How to use C# if else statements

The conditional statement if else in c# language helps you check the conditions you provided in the first part of the if statement and make a decision based on that condition.

if (condition)

  statement;

else

  statement;

For example, we will check the condition to determine if c variable is a-b or b-a

public int Value(int a, int b)
{
    int c = 0;
    if (a > b)
        c = a - b;
    else
        c = b - a;
    return c;
}

If you want to check more than one conditions at the same time, you can use else if statement.

if (condition1)

  statement;

else if (condition2)

  statement;

else

  statement;

For example, you can implement these conditions in the c# program.

string Gender()
{
    bool? gender = null;
    if (gender == null)
    {
        return "???";
    }
    else if (gender == true)
        return "Male";
    else
        return "Female";
}

I hope so, through the c# example above you can understand how to use if...else statements in c# programming.
