Cmd and C# delete file

Question

I'm trying to make an updater in C# and I want to delete the updater once it's done.
So I have this code in C#:

var path = Environment.CurrentDirectory + "\\WindowsFormsApplication1.exe";
Process.Start("cmd.exe /c del " + path);

But I get this error message:

Win32Exception was unhandled
The system cannot find the file specified

But I'm sure the path is spelled right, so I don't think that's the problem.

Any ideas?

Is there a reason you can't use the File.Delete() static method? http://msdn.microsoft.com/en-us/library/system.io.file.delete.aspx — SupremeDud, Apr 17 '12 at 14:45
Try printing out path. I think you'll be surprised at what you see. — Neil, Apr 17 '12 at 14:45
As an aside, you should consider using `System.IO.Path.Combine` to build path strings instead of using straight string concats. — M.Babcock, Apr 17 '12 at 14:47

var path = Environment.CurrentDirectory + "\\WindowsFormsApplication1.exe";

Process process = new Process();
process.StartInfo.FileName = "cmd.exe";
process.StartInfo.Arguments = string.Format("/c del \"{0}\"", path);
process.Start();

Or

Process.Start("cmd.exe", string.Format("/c del \"{0}", path));

how about deleting a folder that is shared that would prompt to confirm the deletion? how to avoid that prompt message and delete it directly? – Juran Aug 15 '17 at 02:16
@Juran sounds like a new question. – Shawn C. Aug 15 '17 at 12:46

This question was answered here: Run Command Prompt Commands

Aditional solution is to build a BAT file and inside it to call del.
