C# OfType() Method
Filter a collection on the basis of each of its elements type.
Let’s say you have the following list with integer and string elements −
list.Add("Katie");
list.Add(100);
list.Add(200);To filter collection and get only elements with string type.
var myStr = from a in list.OfType<string>() select a;
Work the same for integer type.
var myInt = from a in list.OfType<int>() select a;
The following is the complete code −
Example
using System;
using System.Linq;
using System.Collections;
public class Demo {
public static void Main() {
IList list = new ArrayList();
list.Add("Katie");
list.Add(100);
list.Add(200);
list.Add(300);
list.Add(400);
list.Add("Brad");
list.Add(600);
list.Add(700);
var myStr = from a in list.OfType<string>() select a;
var myInt = from a in list.OfType<int>() select a;
Console.WriteLine("Strings...");
foreach (var strVal in myStr) {
Console.WriteLine(strVal);
}
Console.WriteLine("Integer...");
foreach (var intVal in myInt) {
Console.WriteLine(intVal);
}
}
}Output
Strings... Katie Brad Integer... 100 200 300 400 600 700
