Question

If I have a string variable with value as follows :-

string mystring = "TYPE1, TYPE1, TYPE2, TYPE2, TYPE3, TYPE3, TYPE4, TYPE4";

and I want to manipulate this string and make it as follows:-

string mystring = "TYPE1,TYPE2,TYPE3,TYPE4";

ie I want to just remove all the duplicates in it, how should I do it?

Please help. Thanks.

You can do the following:

var parts = mystring.Split(',').Select(s => s.Trim()).Distinct().ToList();
string newString = String.Join(",", parts);
