IV. Program source code (Recycled.cs), compilation method and running interface:
(1). Program source code: Recycled.cs:
Using system.io; using system.windows.forms; // Name space used in the import program Class Recycle {public static void main () {int C = 0; // Define this variable is mainly to determine if there is in the directory File Foreach (String S1 in Directory.GetFiles) / / Returns the enumeration type { C;} if (c> 0) // determines if the file name // If c> 0 recycles station with files, there is no {DialogResult r = messagebox.show ("Is it sure?", "Garbage handling!", Messageboxbuttons.yesno, messagingBoxicon.question; // Display "OK" and " Cancel "two buttons, the icon display is a question mark. INT SS = (int) r; if (ss == 6) // Press the OK button {Foreach (String S in Directory.GetFiles) // Put the full path name { File.delete (s); // Delete this file}}}}}
(2). Compilation method:
After compiling after the following command line, a Windows execution file --RecyCled.exe is formed.
CSC / T: Winexe /R :system.dll /r:system.windows.forms.dll Recycled.cs
Doing this file will get the following execution interface:

5. Summary:
This article is a systematic manner to specifically explain the powerful function of Visual C # through a software system, in fact, in fact, is only a small application in the file processing in Visual C #. Not only that, Visual C # also has a powerful function in other respects. With this powerful backing of .NET Framework SDK, Visual C # makes problems in the previous program have relatively simple, making the problem that is not possible to handle, this is why Visual C # becomes next generation Mainstream programming language.
