执行命令，如“开始”>“在C＃中运行”

Question

I want to create a command executor like Start > Run . The application has a TextBox and when a user enters a command eg : notepad "C:\\test.txt" it should open notepad with this file or %PROGRAMFILES% it should open 'Programs Files' directory.

For %PROGRAMFILES% and other Windows variables I can use Environment.ExpandEnvironmentVariable and get their path and pass to Process.Start

and for notepad, I can split the with space and first part goes in FileName and rest of string goes in Arguments of ProcessStartInfo .

But what I want to know is, how does Start > Run work ? is there something like I can execute the whole command without splitting command-line or expanding the variables ? Maybe with pinvoke ?

Answer 1

To the very best of my knowledge, the run dialog is implemented with a call to ShellExecuteEx . You can achieve the same with Process.Start and UseShellExecute . You do need to expand the environment variables, and split the command into filename and arguments. You already describe how to do that in your question, and, again to the best of my knowledge, there is no programmatic interface to the functionality of the Run dialog.

However, what you can do programmatically is show the Run dialog. Create an instance of the Shell object requesting the IShellDispatch interface, and then call the FileRun method.
