Backslash and quote in command-line arguments

Question

Is the following behaviour some feature or a bug in C# .NET?

Test application:

Answer 1

After much experimentation this worked for me. I'm trying to create a command to send to the Windows command line. A folder name comes after the -graphical option in the command, and since it may have spaces in it, it has to be wrapped in double quotes. When I used back slashes to create the quotes they came out as literals in the command. So this. . . .

string q = @"" + (char) 34;
string strCmdText = string.Format(@"/C cleartool update -graphical {1}{0}{1}", this.txtViewFolder.Text, q);
System.Diagnostics.Process.Start("CMD.exe", strCmdText);

q is a string holding just a double quote character. It's preceded with @ to make it a verbatim string literal.

The command template is also a verbatim string literal, and the string.Format method is used to compile everything into strCmdText.
