Basic use of ANTS performance Profiler
ANTS Performance Profiler is Redgate's powerful performance tuning product, the official product page here.
First look at the basic use of software.
Use the following code for a simple test.
This is a console application, the program is very simple, first 10,000 cycles, output and, then use LINQ in the list to find out the value of 1000 output.
1 static void Main ()
simple test.
This is a console application, the program is very simple, first 10,000 cycles, output and, and then use LINQ in the list to find 1000 of the value output.
Copy Code code as follows:
static void Main ()
{
var list = new list
var sum = 0;
for (var i = 0; i {
sum + = i;
List. ADD (i);
}
Console.WriteLine (sum);
Find the value use linq:1000
var result = list. Where (P => p.equals (1000));
foreach (var i in result)
{
Console.WriteLine (i);

Haha, I did nothing yesterday. I went around in codeproject and saw this article by chance. I understood it, So I translated it. When I practiced English, I also enhanced my understanding of the article, I found that the re-translation has a better understanding of some details of the article. The following is the translation content. Although the translation is very similar to a primary school student's composition, it is very easy to read. I hope you will give more valuable comments. Thank you

One of the factors that often affect the performance of. NET applications is that the Code consumes too much memory. Many developers often do not pay attention to performance when writing code, so that the applicationProg
We all know that. NET has its own memory (garbage) recovery mechanism, unless there is some data (methods) of long-term possession of memory does not follow the garbage collection function to free memory, so that we often say that the memory leaks,
