a look at how the Task class is used. The Task class is commonly called a Task in Chinese. So there is a saying. Single task or multi-task. Why does the author say this? As follows.
1. single task. Is a Task instance. This is relatively simple. The Code is as follows:
Class Program {static void Main (string [] args) {CancellationTokenSource cts = new CancellationTokenSource (); // used to cancel the Task myTask = new Task (obj) => {Console. writeLine

9. cache priority
Like the expiration Policy, the cache priority is also MemoryCacheEntryOptions:
MemoryCacheEntryOptions options = new MemoryCacheEntryOptions();options.Priority = CacheItemPriority.Normal;cache.Set
CacheItemPriority enumeration values are normal, high, and permanently retained.10. Set the dependency between caches.
You can set dependencies for cache data to delete cache items that are dependent on th

2. Basic Concepts
In C #, whether a variable is a value or a reference only depends on its data type.
The basic data types of C # are defined in a platform-independent manner. The pre-defined types of C # are not built into the language, but are built into the. NET Framework .. . Net uses a general type System (
Framework provides the CancellationTokenSource class as the unified mode for thread cancellation. For example:Copy codeThe Code is as follows: public class Example{Public static void Main (){CancellationTokenSource cts = new CancellationTokenSource ();Var thread = new Thread (ThreadWork );Thread. Start (cts. Token );While (true){If (Console. ReadKey (). KeyChar = 'C '){Console. WriteLine ("request cancella

Maybe it's because the thread class and the ThreadPool class are too difficult to control. Then this is not the problem I am concerned about. Let's take a look at how the task class is used.

Copy Code code as follows:

var thread = new Thread (threadwork);
Thread. Start (CTS. Token);

shows the simplicity of using reflection to perform late binding in managed objects. If you build the code in Figure 1 and run it within LateBinder.exe, you can pass the name of any assembly, such as the Assembly built from code in Figure 2, to it as a command-line argument. LateBinder.exe reflects the assembly and creates instances of the classes derived from Form in the assembly and makes them its own MDI child classes. Reflection in the. NET Framework simplifies late binding greatly.

rate. During transmission, the receiver finds that the input buffer is full because the CPU is busy with other work. To temporarily stop transmission, the receiver sends XOFF. The typical value is decimal 19, that is, hexadecimal 13, until the input buffer is empty. Once the receiver is ready to receive the message, it sends XON, the typical value is decimal 17, that is, hexadecimal 11, continue communication. When the input buffer is half full, LabWindows sends XOFF. In addition, if the XOFF t

(1) Using the flag method to confirm that there is a problem, the interrupt response function is not re-entered;
Conclusion: The interrupt response function is not re-entered.
