Linq is very easy to read and simplifies the code. In this example we will learn about grouping and sorting using linq. Here we are filtering and Listing the group of words by string length from a string array.
Example:
static void Main(string[] args)
{
string[] words = { "Frequency", "wonderful", "Honeypot", "Halftone", "Hyperlink", "Navigation", "Footer" };
var groups = from word in words
orderby word ascending
group word
by word.Length into lengthGroups
orderby lengthGroups.Key descending
select new { Length = lengthGroups.Key, Words = lengthGroups };
foreach (var group in groups)
{
Console.WriteLine("Words of length " + group.Length);
foreach (string word in group.Words)
Console.WriteLine(" " + word);
}
Console.ReadLine();
}
Output:
