在C#中计算时间差通常使用DateTime结构来表示时间,可以通过DateTime.Now属性获取当前时间。下面是一些提升应用性能的技巧:
Stopwatch stopwatch = new Stopwatch();
stopwatch.Start();
// Perform some operation
stopwatch.Stop();
TimeSpan elapsedTime = stopwatch.Elapsed;
Console.WriteLine("Elapsed time: " + elapsedTime.ToString());
DateTime startTime = DateTime.Now;
// Perform some operation
DateTime endTime = DateTime.Now;
TimeSpan elapsedTime = endTime - startTime;
Console.WriteLine("Elapsed time: " + elapsedTime.ToString());
async Task PerformOperationAsync()
{
Stopwatch stopwatch = new Stopwatch();
stopwatch.Start();
// Perform some time-consuming operation asynchronously
await Task.Run(() =>
{
// Perform some operation
});
stopwatch.Stop();
TimeSpan elapsedTime = stopwatch.Elapsed;
Console.WriteLine("Elapsed time: " + elapsedTime.ToString());
}
通过以上技巧,可以更高效地计算时间差并提升应用性能。
