I talked with others about the performance of linq yesterday. I feel that the performance of linq is not good, but in fact it is still outstanding in terms of performance, except for the ability to write data to SQL, the following is a simple performance test comparison code. Here I will explain that the execution speed of the Code cannot be tested using datetime. I am still a little white, just starting with datetime, the results showed that the performance of the linq service was not good, but

In a project, it is often necessary to log records of execution performance (time spent) of some methods, which are implemented in two ways.StopWatchUsing the Stopwatch class to measure time is very simple. Like the stopwatch in real life, this class of objects can start, stop, zero (reset) operations on the counter, but it is much more accurate than the average stopwat
It seems boring, but no one is doing it. Let me work hard. Below are some simple tests. The Unit is ms. Note that the number of loops used here is 100, and the number of loops is. These records can be used as a reference for programming.

method for obtaining objects. This method is used with constructor, factory, and service locator (such as JNDI )) compared with traditional methods, these methods provide better reusability, testability, and maintainability. The processing process of this method is a well-known dependency injection, which is very valuable to most applications. In our program, many types depend on other types. For example, a stopwatch may depend on a timesource. If so
already has a common hump representation, split it up by its composition (such as "AdWords" will split into "ad words"). It is important to note that "IOS" is not a real hump representation, so the recommendation does not apply to it. Now all the letters are lowercase (including abbreviations), and then capitalize the first letter of the word: The first letter of each word is capitalized, and comes to a large hump-type name. In addition to the first word, the first le
. lowercase all letters (including abbreviations) and capitalize the first letter of a word: Capitalize the first letter of each word to get a big hump-named (uppercamelcase) In addition to the first word, the first letter of each word is capitalized to get the small hump-type name (Lowercamelcase) Finally, link all the words together to get a representation.

In this case, the time for issuing the ticket will be 10 minutes-> 20 seconds. This is amazing. Now, let's go to the demo, test, and change it to a method test that we generally use. nnd is really fast. Paste my demo: sqlbulkcopy.rar here CopyCode The Code is as follows: Using system; Using system. diagnostics; Using system. Data; Using system. Data. sqlclient; Using Microsoft. applicationblocks.

Many times it takes time for the output program to be recorded,always start recording the current point of time at the beginning of the program execution, at the end of the record end point in time, and then subtract two times,so is there any other way to be a little bit more presentable? Tell you, there is a drop; )the subject of this method is StopwatchHis description is: For accurate measurement of the running time, you need to record time-consuming students who applause?Specific use:System.D
