Study Notes

The loop condition in a while loop in C# is a boolean expression that determines whether the loop will continue to execute or terminate.

The loop condition is evaluated at the beginning of each iteration.
The loop will continue to execute as long as the condition is true.
The loop will terminate when the condition becomes false.
The condition can be any valid C# boolean expression, including variables, literals, and method calls.

int i = 0;
while (i &lt; 5) 
{
    Console.WriteLine(i);
    i++;
}

In this example, the loop condition is i < 5. The loop will continue to execute as long as i is less than 5.

Keep the loop condition simple and easy to understand.
Avoid complex expressions or method calls that could slow down the loop.
Use meaningful variable names to make the loop condition clear.
Consider using a boolean variable to store the loop condition, especially if it's complex or reused.
