C# 委托 Action 实现代码执行时间日志记录

思路比较简单直接上代码

public void TimeLog(string title, Action action)
{
    Stopwatch stopwatch = new Stopwatch();
    stopwatch.Start();
    //方法执行
    action.Invoke();
    stopwatch.Stop();
    File.AppendAllLines("D:\\Projects\\ExecutionTimeLog\\Log.txt", new[] { title + " 执行耗时:" + stopwatch.Elapsed.TotalSeconds });
}

调用

int res = 0;
TimeLog("Test", () =>
{
    res = new Program().Test4(1);
    res = 3;
});
Console.WriteLine(res);
