Remove all empty elements from string array

I have this:

List<string> s = new List<string>{"", "a", "", "b", "", "c"};

I want to remove all the empty elements ("") from it quickly (probably through LINQ) without using a foreach statement because that makes the code look ugly.

I write below code to remove the blank value

List<string> s = new List<string>{"", "a", "", "b", "", "c"};
s = s.Where(t => !string.IsNullOrWhiteSpace(t)).Distinct().ToList();

Check out with List.RemoveAll with String.IsNullOrEmpty() method;

Indicates whether the specified string is null or an Empty string.

s.RemoveAll(str => string.IsNullOrEmpty(str));

Here is a DEMO.

You can use List.RemoveAll:

C#

s.RemoveAll(str => String.IsNullOrEmpty(str));

VB.NET

s.RemoveAll(Function(str) String.IsNullOrEmpty(str))
