How to get all Uppercase or Lowercase word using LINQ in C#

In this post, I'll show how you can filter out uppercase or lowercase words in a string

Code to find uppercase or lowercase words in given string:

var str = "Test String With lower And UPPER Case"; //Find all Uppercase words var upperItems = str.Split(' ')                 .Where(s => String.Equals(s, s.ToUpper(),                                             StringComparison.Ordinal)); //Find all Lowercase words var lowerItems = str.Split(' ')                 .Where(s => String.Equals(s, s.ToLower(),                                             StringComparison.Ordinal));

Output: You can check upperItems contains one word “UPPER” and lowerItems contains one word as well i.e. “lower”
