Remove all empty elements from string array

Question

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.

Solution 1

You can use List.RemoveAll:

C#

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

VB.NET

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

Solution 2

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.

Solution 3

s = s.Where(val => !string.IsNullOrEmpty(val)).ToList();
