VB.Net – OfType() LINQ Extension Method

In this program, we will use OfType() LINQ extension method to get the string elements from the array list and print them on the console screen.

Program/Source Code:

The source code to demonstrate the OfType() LINQ extension method is given below. The given program is compiled and executed successfully.

Explanation

In the above program, we created a module Module1 that contains the Main() function. The Main() function is the entry point for the program.

In the Main() function, We created an array list that contains mixed elements that may be integer or string. Here, we used OfType() LINQ extension method to find out the string elements from the array list and then print them on the console screen.
