将字符串中的值提取到数组中

Question

I have a string like this:

john "is my best buddy" and he loves "strawberry juice"

I want to-

• Extract texts within double-quotes into a string array array1
• Split texts outside of double-quotes by spaces and then insert them into another string array ( array2 ).

Output:

array1[0] : is my best buddy

array1[1] : strawberry juice

array2[0] : john

array2[1] : and

array2[2] : he

array2[3] : loves

Any help is appreciated.

Clearly, this is a call for Regular Expressions:

var str = @"john ""is my best buddy"" and he loves ""strawberry juice""";

var regex = new Regex("(\"(?'quoted'[^\"]+)\")|(?'word'\\w+)",
                   RegexOptions.Singleline|RegexOptions.Compiled);

var matches = regex.Matches(str);

var quotes = matches.Cast<Match>()
                    .SelectMany(m => m.Groups.Cast<Group>())
                    .Where(g => g.Name == "quoted" && g.Success)
                    .Select(g => g.Value)
                    .ToArray();

var words = matches.Cast<Match>()
                    .SelectMany(m => m.Groups.Cast<Group>())
                    .Where(g => g.Name == "word" && g.Success)
                    .Select(g => g.Value)
                    .ToArray();
