Question

I need to split a custom string into the following format using C#.

The following string: AD=Demo,OU=WEB,OU=IT,L=MyCity,C=MyCountry, i want to split it at comma into a

List<CustomDictionary> myList = new
List<CustomDictionary>();

Based on the text above and after the split, the myList list should contain 5 objects of type CustomDictionary.

 object1.Key = AD
 object1.Value = Demo

 object2.Key = OU
 object2.Value = WEB

 object3.Key = OU
 object3.Value = IT

 object4.Key = L
 object4.Value = MyCity

 object5.Key = C
 object5.Value = MyCountry

Here is the CustomObject class

 public class CustomDictionary
 {
     public string Key { get; set; }
     public string Value { get; set; }

     public CustomDictionary(string key, string value)
     {
         this.Key = key;
         this.Value = value;
     }
 }

So far I tried this:

Here I am stuck!

  List<CustomDictionary> keyVal = new List<CustomDictionary>val.Split(',').Select(x=>x.Split('=')).Select(x=>x.));

where val is the actual string …

Answer 1

With linq:

var query = from x in str.Split(',')
            let p = x.Split('=')
            select new CustomDictionary(p[0], p[1]);

var list = query.ToList();

Also seems like you want to get a dictionary as a result. If so, try this code:

var dict = str.Split(',').Select(x => x.Split('='))
                         .ToDictionary(x => x[0], x => x[1]);

To handle duplicate keys, you can store objects in Lookup. Just call ToLookup instead of ToDictionaty.
