How to split a string into a dictionary using multiple delimiters as a key
I have a line that looks like this:
var givenString = "Id: some id Title: sometitle Descritpion: some description Criteria: some criteria <br>more criteria"
How can I split it into a dictionary where the delimiter is the key and the value is a given string. It is also possible that one of the delimiters is not in the text.
I know how to split it into a sentence, but I don't know how to deal with a situation where one of the delimiters is missing and how to split it into a dictionary.
string[] separators = { "Id:", "Title:", "Descritpion", "Criteria:" };
string[] words = givenString.Split(separators, StringSplitOptions.None);
EDIT1: Example with missing separator:
var givenString = "Id: some id Title: sometitle Criteria: some criteria <br>more criteria"
EDIT2 I forget that some delimiters can be two words :( If it makes it simpler, I might ask to change the delimiters written with a capital letter:
var givenString = "ID: some id TITLE: sometitle CRITERIA: some criteria <br>more criteria, DIFFERENT CRITERIA: some criteria <br>more criteria"

To break into a pattern (letters A..Za..z
followed by a column :
), I suggest using regular expressions, Regex.Split, instead of givenString.Split
:
string givenString =
@"Id: some id Title: sometitle Descritpion: some description Criteria: some criteria <br>more criteria";
Dictionary<string, string> result = Regex
.Split(givenString, "([A-Z][a-z]+ [A-Z][a-z]+:)|([A-Z][a-z]+:)")
.Skip(1) // <- skip (empty) chunk before the 1st separator
.Select((item, index) => new { // pair: separator followed by value
value = item.Trim(),
index = index / 2 })
.GroupBy(item => item.index)
.ToDictionary(chunk => chunk.First().value.TrimEnd(':'),
chunk => chunk.Last().value);
Test:
string report = string.Join(Environment.NewLine, result
.Select(pair => $"Key = {pair.Key,-12} Value = \"{pair.Value}\""));
Console.Write(report);
Result:
Key = Id Value = "some id"
Key = Title Value = "sometitle"
Key = Descritpion Value = "some description"
Key = Criteria Value = "some criteria <br>more criteria"
