A Detailed Guide to C# TimeSpan

The C# TimeSpan struct represents a time interval and can be used in any .NET language. It is more robust than using primitive types like int to represent durations, as it reduces the likelihood of bugs and makes code more readable. There are several ways to obtain a TimeSpan value, including subtracting two DateTime values, using factory methods, adding multiple TimeSpans together, or using constructors with different parameters. Key methods associated with TimeSpan include Add, Subtract, Multiply, Divide, Negate, and Duration, while key properties include Days, Hours, Milliseconds, Minutes, Seconds, Ticks, TotalDays, TotalHours, TotalMilliseconds, TotalMinutes, and TotalSeconds. TimeSpan can be formatted using the ToString() method or by accessing its properties directly. Common issues with TimeSpan include parsing errors, misunderstanding the components, and faulty arithmetic related to daylight saving time transitions.
