with C#winform write a simple gadget for bulk emptying of file contents and deleting files

This article describes a small project that is simply not simple enough. To do this project, there are the following purposes.

1	Of course, it's a tool to use.
2	Learn to use GitHub

For a tutorial on creating a project with VS2013 and adding it to GitHub, see (http://www.admin10000.com/document/4004.html). To put it simply, create a project with VS, then create a RESPO (code-managed project for this project) on the GitHub site, write down the address (https://*.git), and then synchronize the code to the server with the "commit" and "Sync" buttons.

This gadget I named Filewiper, whose GitHub address is (https://github.com/bitzhuwei/FileWiper.git), welcome to the discussion.

Using GitHub

There is a warehouse, called Repo A. If you want to contribute to the code, first fork this repo, so in your GitHub account has a repo A2,. Then you work under this A2, Commit,push and so on. Then you want the original warehouse repo A to merge your work, you can launch a pull request on GitHub, which means request repo A's owner to merge branches from your A2. If it is approved and formally merged, then you contribute to project A.

Empty file contents

Just open the file and overwrite the original content.

public static void wipefilecontent (string filename) { using (var stream = New System.IO. StreamWriter(filename, false)) { Stream. Write ("http://bitzhuwei.cnblogs.com"); } }

Register to the System right-click menu

Register with the RegistryKey.

The program path is followed by a " %1" so that at startup, the args parameter in the main function contains the selected file path (or folder path).

Still implemented with RegistryKey.
