After locating the leaked objects through a series of analysis and diagnostics above, find out which objects they are referenced by, that is, which objects in Root Path, by modifying the code to cut off references that should not exist, so that the leaking object can be unreachable in a normal state, GC Threads will also handle them correctly.

If it is a WPF application, there are common problems with the release of Image objects. The attributes of objects bound to non-dependent attributes or that do not implement the INotifyPropertyChanged interface are not described here.

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:

{
var list = new list
var sum = 0;
for (var i = 0; i {
sum + = i;
List. ADD (i);
}
Console.WriteLine (sum);

First, prefaceIn recent times, there have been two problems with websites:1. Memory usage increases slightly until the server memory fills up.2. When you visit a page, the page responds too slowly and the CPU stays high.An initial estimate of memory growth may be due to the fact that there are unsaved resources that are taking up

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.
