Concatenate string literals with DirectoryInfo enumeration and adding quotation marks.

Question

This seems like such an obscure question, but here it goes:

Is there a way to concatenate String Literals with a DirectoryInfo enumeration (which contains a file path) while adding quotations around the file path? Further, how can I prevent backslashes from being doubled when converting a DirectoryInfo enumeration to a string? My situation is as follows:

DirectoryInfo filePathDirectory = new DirectoryInfo(filePath);
Process a = new Process();

a.StartInfo.FileName = "C:\\Windows\\system32\\lpr.exe";
a.StartInfo.Arguments = "-SServername.Domain.net -Plp " + "\"" + filePathDirectory + "\"";
a.StartInfo.UseShellExecute = false;
a.Start();
a.WaitForExit();

filePathDirectory starts with a value of:

{\\ServerName\Share\Folder\Folder\FileName.xls}

Which I think is converted into a string once concatenated into a.StartInfo.Arguments which is assigned the value of:

-SServername.Domain.net -Plp \"\\\\ServerName\\Share\\Folder\\Folder\\FileName.xls\"

This is bad because, the number of backslashes in the path doubled. How can I ensure no backslashes are added to the path?

On top of that, to add a quotation marks, I've used the backslash escape sequence; But the backslash from this escape sequence is inadvertently added to my string. How can I add quotation marks around the file path which is contained in a.StartInfo.Arguments?

P.S. I hope this makes sense, please ask questions if you need clarification.

The backslashes are not doubled and the backslash of the quotes also "isn't there". You can verify it by Console.WriteLine(a.StartInfo.Arguments) or MessageBox.Show(a.StartInfo.Arguments).

What you are seeing - in the debugger I assume - is the representation of the string with the escape characters not translated - just as you would need to enter it in the IDE.

Example:

string s = "\"";

This will show in the debugger as "\"" but it will display on screen as ":
