I have string variable that has value like this
string hello = "Endpoint: Efficacy, Intervene: Single Group, Mask: Open, Purpose: Treatment";
As I am extracting from XML so Endpoint , Intervene , Mask and Purpose remains
same but its value can change.
I want to store this Endpoint , intervene , mask and purpose separately in different variables any help will be much appreciated.
var result = hello.Split(',')
.Select(part => part.Split(':'))
.ToDictionary(split => split[0], split => split[1].Trim());
Try this way using Dictionary
string hello = "Endpoint: Efficacy, Intervene: Single Group, Mask: Open, Purpose: Treatment";
Dictionary<string, string> result = new Dictionary<string, string>();
var s1 = hello.Split(',');
foreach (var s in s1)
{
var v = s.Split(':');
result.Add(v[0].Trim(), v[1].Trim());
}
After that you can get result using key value of the Dictionary
foreach (var a in result)
{
Console.WriteLine(a.Key +" " + a.Value);
}
Split your string first by , and then by : and save the result in dictionary:
public class Program
{
public static void Main(string[] args)
{
string hello = "Endpoint: Efficacy, Intervene: Single Group, Mask: Open, Purpose: Treatment";
string[] arr = hello.Split(',');
Dictionary<string, string> result = new Dictionary<string, string>();
foreach(string s in arr)
{
string[] keyValuePair = s.Split(':');
result[keyValuePair[0].Replace(" ","")] = keyValuePair[1].Replace(" ","");
}
foreach(var v in result)
{
Console.WriteLine(v.Key + " : " + v.Value );
}
}
}
If the pattern is fixed, this can help you.
string hello = "Endpoint: Efficacy, Intervene: Single Group, Mask: Open, Purpose: Treatment";
string[] packs = hello.Split(',');
var data = packs.ToDictionary(k => k.Split(':').First().Trim(), v => v.Split(':').Last().Trim());
I came up with something more dynamic just in case someone have to deal with variable keywords to match.
This first extracts the keywords and builds a pattern to match. Matches are then captured by name and each capture group is named after a keyword so that we can access them by keyword:
var input = "Endpoint: Efficacy, Intervene: Single Group, Mask: Open, Purpose: Treatment";
//extract keywords: (word followed by ':' )
var keywords = Regex.Matches( input, @"(\w*):" ).Cast<Match>()
.Select( m => m.Groups[ 1 ].Value );
//build the pattern to match (create capture groups named as keywords)
var pattern = String.Join( ", ", keywords.Select(
k => k + $@": (?<{k}>(\w*\s*)*)" ) );
var matches = Regex.Matches( input, pattern );
//access groups by keyword
foreach( var keyword in keywords )
Console.WriteLine( matches[ 0 ].Groups[ keyword ].Value );
