C# Linq SelectMany Method
Use SelectMany method to collapse elements into a single collection like an error.
An example would be to convert string to character array. The following is our string array.
string[] str = { "Mobile", "Laptop", "Tablet" };
Now, convert to character array.
str.SelectMany(item => item.ToCharArray());
Example
using System; using System.Linq; using System.Collections.Generic; public class Demo { public static void Main() { string[] str = { "Mobile", "Laptop", "Tablet" }; var res = str.SelectMany(item => item.ToCharArray()); Console.WriteLine("String converted to character array: "); foreach (char letter in res) { Console.Write(letter); } } }
Output
String converted to character array: MobileLaptopTablet
