C # Install and uninstall a tool for Windows Services-source code
In our work, we often encounter installation and uninstallation of Windows Services. In the past, the company also wrote a WinForm program to select the installation path. This time, we came up with a small and flexible console program, you do not need to choose any more. You can install or uninstall the service by running it in the directory where you want to install the service. Development Concept 1. Due to system permission restrictions, you must run the program as an administrator. 2. You need to install and uninstall the program, when the program is running, the system prompts whether to install or uninstall the program. Enter 1 or 2. The program will find the executable files in the current directory and filter the program itself and the files with vhost file, and list the list for the operator to select (usually only one) 4. install or uninstall based on the user's choice 5. due to repeated operations, you need to call the specific implementation recursively first to operate the service, you need to use System. serviceProcess to encapsulate implementation classes

Next, we encapsulate the console operation method. recursion is used here to implement loop listening.
