How to remove duplicate words from a string

[bertjangroeneveld]

Hi there,

I am running into a problem which I can’t fix.
There are some simular topics about it but for me it doesn’t do the trick.
In a string (strInput) I have the text: “CAT cat caterpillar S3 ESD”
I would like to remove the second ‘cat’
So the result must be:
CAT caterpillar S3 ESD

I tried:
String.Join(" “, strInput.Split(” “c).Distinct())
or
String.Join(” “, strInput.ToLower.Split(” "c).Distinct())

The first one doesn’t do anything and the second one works but returns the complete string in lowercases. I would like to keep the uppercases (CAT caterpillar S3 ESD)

Who is my hero of the day with the right solution?

Many, many thanks in advance!

You can follow this approach:

Here is strOutput logic:

String.Join(" ", strInput.Split(" "c).Distinct(StringComparer.OrdinalIgnoreCase).ToArray())

Output:
