. Net2.0 also provides the stopwatch class, which can accurately measure the time.
Speed test:
The performance and testability of software is a complex topic. To ensure that an application meets your expectations, you need to consider its performance and testability during the development cycle. This is crucial in the design phase, and a poor design will almost certainly lead to a poor user experience. However, only a good design does not ensure that
Stopwatch and stopwatch
Stopwatch:Stopwatch timer, used to record the running time of the program, usually used to test the code execution efficiency in time. (Reference: System. Diagnostics .)Stopwatch sw = new Stopwatch (); // instantiate an object.
Sw. Start ():Enable the timer.
Sw. Stop ():Disable the timer.

Ideas:
1. Add the upper part of the stopwatch, for example, 00: 00: 00. 00, which respectively indicates the time, minute, second, and millisecond. A total of seven labe are used for implementation.
2. Set the buttons to start, stop, and reset.
3.

Instance code:
When the timer is set to run interval, 100 is set at the beginning. In fact, it is incorrect because 1 second = 1000 milliseconds. We need to divide it into 60 numbers for display, therefore, we need to divide it by 60.

Introduction
Every person who uses the stopwatch class in the system. Diagnostics namespace for performance optimization will encounter some troubles sooner or later. As you can see, tests with the same function on the same computer may differ from 25% to 30% during running time. This article describes how to use the stopwatch class to design a single-thread TestProgram0.1%-0.2% accuracy. With this precis
The running speed of the software must be within the acceptable range of users. Generally, improving the speed of short but frequently used routines greatly increases the overall speed of the software.
To improve the speed, you must first be able to measure the time. Well, let's take a look at the scene on the runway. When the gunshots hit, we immediately press the stopwatch to start timing and end timing when the contestant reaches the finish point,
question one: the last few days to write the actual application of parallel computing-the Address book, the use of stopwatch to time, found that the timing is the real timing.Stopwatch Stopwatch =NewStopwatch (); TimeSpan TimeSpan; Doubletime1,time2; Stopwatch. Start (); F1 ();//Take time T1stopwatch. Stop (); TimeSpan=
1. Use Stopwatch class (System.Diagnostics.Stopwatch)Stopwatch instances can measure the elapsed time of a single time interval, or they can measure the total elapsed time of multiple time intervals. In a typical Stopwatch scenario, call the Start method, then call the Stop method, and finally use the Elapsed property to check the run time. The

The shell of the stopwatch is metal, the texture part of the production is more troublesome. At the same time different parts of the production method is different. The ring section can be textured with a layer style, and the key part needs to be made with a metal gradient.

The running speed of the software must be within the acceptable range of the user. Generally, improving the speed of those short but frequently used routines can significantly improve the overall speed of the software.
To improve speed, of course, we must first be able to measure time. OK, so let's think about the situation on the runway, the sound of the gunshot, immediately press the stopwatch to start the time, the player reached the end of the mo
1 Overview
You need to record the execution time of each task, or record a period of code execution, simply by printing the difference between the current time and the execution time, and if performing a large number of tests is cumbersome and not intuitive. If you want to control the execution time further, you need to modify it in many parts of the program. Spring-framework provides a stopwatch class that can do similar task execution time contro

In C #, DateTime is typically used to represent the current time, and you can use a DateTime object to get the current time before and after an operation, and then subtract two DateTime objects to get the time difference (TimeSpan object), so that this operation takes a lot longer.However, in some cases, a loop fetch is required to perform an operation, and this operation may not take much time, but the time spent is still considerable when the magnitude of the loop is large. It would be trouble
