LINQ to Strings
In this example we will write LINQ queries on string to find distinct words in the string and duplicate words in the string.
LINQ Query:
Below query will split the string into words order by words length.
string input = "linq to string example";
var wordsorderbylength = from str in input.Split(new char[] { ' ' }, StringSplitOptions.RemoveEmptyEntries)
orderby str.Length
select new { WordsOrderByLength = str };
gvLength.DataSource = wordsorderbylength;
gvLength.DataBind();
Output:
WordsOrderByLength

example
LINQ Query:
Below query will find the distinct words in the string order by words.
string input1 = "hi Hellow HI world hellow world world hi hi";
var wordsuinque = from str in input1.ToLowerInvariant().Split().Distinct()
select new { DistinctWords = str };
gvUniqueWords.DataSource = wordsuinque;
gvUniqueWords.DataBind();
Output:
DistinctWords
hi
hellow
world
LINQ Query:
Below query will find the duplicate words in the string order by words.
string input2 = "This sentance contains duplicate words and the following linq query will find the duplicate words in this sentance";
var duplicatewords = from str in input2.ToLowerInvariant().Split()
group str by str into temp
orderby temp.Key
where temp.Count() > 1
select new { DuplicateWords = temp.Key };
gvDuplicateWords.DataSource = duplicatewords;
gvDuplicateWords.DataBind();
Output:
DuplicateWords
duplicate
