Can you explain what the keyword Throw means in programming?

The throw keyword in C# is used for explicitly throwing an exception. It interrupts the normal flow of the program and transfers control to the exception handler.

Example:

if (value < 0)
{
    throw new ArgumentException("Value cannot be negative");
}

Here, if the condition is true, an ArgumentException is created and thrown. This signals an error that can be caught in a try-catch block.
