Remove duplicates within a List, ignore case and whitespace

You can do try this, pass List of strings Varibale in For each loop and mention the input as lstVar.Distinct .|

This is a similar question for this, I don’t know if it will ignore whitespace or ignore case:

Delete duplicates in collection

Hi @CamiCat Use like this in assign list int<32> Intarray=intarray.Distinct().ToList() print the item Thanks Ashwin S

To ignore case you can use this:

list.Distinct(
    StringComparer.CurrentCultureIgnoreCase).ToList();

More details about question you can find here:

LINQ Distinct operator, ignore case?

For whitespace it is more complex since it is not a problem of a distinct function but a form of data so can you clean data before you go into filtering?
