How to select Only string values from ArrayList using Link in Asp.net.

Introduction:-

In this article I have explained how to select only string values from ArrayList using Linq.

Code:-

Don't forget to add namespace:-

using System.Linq;

Write the following code in page load:-

protected void Page_Load(object sender, EventArgs e)

    {

        Label1.Text = string.Empty;

        ArrayList al = new ArrayList { "Hello", 200, "World", false, 100 };

        var onlyStr = al.OfType<string>();

        Console.WriteLine("Printing Only Strings");

        foreach (var str in onlyStr)

         Label1.Text +=   str.ToString()+"\n";

      

    }

For Console write the following Code:-

ArrayList al = new ArrayList { "Hello", 200, "World", false, 100 };

        var onlyStr = al.OfType<string>();

        Console.WriteLine("Printing Only Strings");

        foreach (var str in onlyStr)

 Console.WriteLine(str);

Console.ReadLine();

}

Run the code and check the result.
