How to create a comma delimited string from distinct list of values using LINQ?

Question

I have a list of values:

Click to copy

myCars

with values:

Click to copy

Ford
Ford
VW
Renault
Jeep
Jeep

which is referenced via:

Click to copy

myCars.Makers

I wish to create a distinct comma delimited string from this such that I get:

Click to copy

Ford,VW,Renault,Jeep

I am guessing that I need to run a distinct clause on myCars, but then am unsure about how to convert to comma delimited string as above.

Many thanks in advance

Answer 1

use string.Join and Distinct

Click to copy

string.Join(",", myCars.Makers.Distinct());
