Question

closing delimiter "\\" unexpected character .

Answer 1

The @ symbol in front of the string specifier instructs the C# compiler to use a different escape mechanism for the string, effectively ignoring all of the standard escape sequences and rendering them as text. The only escape sequence that is used in the alternate form of string specifier is the "" escape sequence which inserts a single " character in the output.

Try your string as:

start.FileName = @"C:/Program Files/xyz/asd -config ""C:/Users/xyz/qwe""";

Or:

start.FileName = "C:/Program Files/xyz/asd -config \"C:/Users/xyz/qwe\"";

Either one works. Or, since you're targeting a windows platform:

start.FileName = @"C:\Program Files\xyz\asd -config ""C:\Users\xyz\qwe""";

The advantage of verbatim strings is that escape sequences are not processed, which makes it easy to write, for example, a fully qualified file name: C#

@"c:\Docs\Source\a.txt"  // rather than "c:\\Docs\\Source\\a.txt"

To include a double quotation mark in an @-quoted string, double it:

@"""Ahoy!"" cried the captain." // "Ahoy!" cried the captain.

string line = "C:/Program Files/xyz/asd -config \"C:/Users/xyz/qwe**\"";

Console.WriteLine(line);
