Question

I wonder if I can transform this:

"abc , 123; xyz, 100; go, 9; move, 50;"

into this:

{ { "abc", "123" } , { "xyz" , "100" } , { "go" , "9" } , { "move" , "50" } }

(array of string[2]) with one long concatenated LINQ statement ?

Edit:

a from-in-where-select statements series is preferred

Edit 2:

also, is there also a way to transform the input string into some composite type like array of struct { string, int } or some Tuple<string,int> ?

like:

{
    new Tuple<string, int>() { "abc", 123 } ,
    new Tuple<string, int>() { "xyz" , 100 } ,
    new Tuple<string, int>() { "go" , 9 } ,
    new Tuple<string, int>() { "move" , 50 }
}

?

Answer 1

With String.Split abd String.Trim and LINQ select.

var result = (from keyValuePair in myString.Split(';')
              where keyValuePair.Trim() != ""
              select (from t in keyValuePair.Split(',')
                      select t.Trim()).ToArray()).ToArray();()

UPDATE

To have an array of KeyValuePair<string, int>

var result = (from keyValuePair in myString.Split(';')
              where keyValuePair.Trim() != ""
              let splittedKeyValuePair = keyValuePair.Split(',')
              select new KeyValuePair<string, int>(splittedKeyValuePair[0].Trim(), int.Parse(splittedKeyValuePair[1]))).ToArray();

To have an Dictionary<string, int>

var result = (from keyValuePair in myString.Split(';')
              where keyValuePair.Trim() != ""
              select keyValuePair.Split(',')).ToDictionary(kvp => kvp[0].Trim(), kvp => int.Parse(kvp[1]))
