SUNWEN tutorial - C# advanced (2)
Okay, I COME BACK, the following code shows how we print multiple parameters:
000: // CommandLinecmdline1.cs
001: using System;
002:
003: public class CommandLine
004: {
005 : public static void Main(string[] args)
006: {
007: Console.WriteLine("Number of command line parameters = {0}", args.Length);
008: for(int i = 0; i < args.Length; i++)
009: {
010: Console.WriteLine("Arg[{0}] = [{1}]", i, args[i]);
011: }
012: }
013: }
If your input is:
cmdline1 A B C
then its output is:
Number of command line parameters = 3
Arg[0] = [A]
Arg[1] = [B]
Arg[2] = [C]
Haha, you have seen the secret! Yes {0} is a mark, which tells the system that it is reserved for the 0th parameter. In the program, this The 0th parameter is i. Therefore, what is printed is Arg[0], not Arg[{0}], haha!
Example 2 shows you the usage of the foreach statement. In fact, in asp, this Frequently used:
000: // CommandLinecmdline2.cs
001: using System;
002:
003: public class CommandLine2
004: {
005: public static void Main(string[] args)
006: {
007: Console.WriteLine("Number of command line parameters = {0}", args.Length);
008: foreach(string s in args)
009: {
010: Console.WriteLine(s);
011 : }
012: }
013: }
Obviously, args is an array, and it is of character type. foreach means to loop through all the elements in it. The result is:
>cmdline2 John Paul Mary
Number of command line parameters = 3
John
Paul
Mary
Okay, comrades, take a rest, I’m going to bed! 88, see you next time!

The difference between multithreading and asynchronous is that multithreading executes multiple threads at the same time, while asynchronously performs operations without blocking the current thread. Multithreading is used for compute-intensive tasks, while asynchronously is used for user interaction. The advantage of multi-threading is to improve computing performance, while the advantage of asynchronous is to not block UI threads. Choosing multithreading or asynchronous depends on the nature of the task: Computation-intensive tasks use multithreading, tasks that interact with external resources and need to keep UI responsiveness use asynchronous.
