There's a pretty good implementation by Daniel Earwicker
on StackOverflow[
^]:
public static string TrimMatchingQuotes(this string input, char quote)
{
if ((input.Length >= 2) &&
(input[0] == quote) && (input[input.Length - 1] == quote))
return input.Substring(1, input.Length - 2);
return input;
}
public static IEnumerable<string> Split(this string str, Func<char, bool> controller)
{
int nextPiece = 0;
for (int c = 0; c < str.Length; c++)
{
if (controller(str[c]))
{
yield return str.Substring(nextPiece, c - nextPiece);
nextPiece = c + 1;
}
}
yield return str.Substring(nextPiece);
}
public static IEnumerable<string> SplitCommandLine(string commandLine)
{
bool inQuotes = false;
return commandLine.Split(c =>
{
if (c == '\"') inQuotes = !inQuotes;
return !inQuotes && c == ' ';
})
.Select(arg => arg.Trim().TrimMatchingQuotes('\"'))
.Where(arg => !string.IsNullOrEmpty(arg));
}
The same thread also includes
the P/Invoke solution[
