Summary: Learn how to integrate LINQ (Language Integrated Query) into your Windows Forms and WPF applications using C# for enhanced data querying and manipulation capabilities.
---

LINQ (Language Integrated Query) is a powerful feature in C that allows developers to query data from various sources such as collections, arrays, XML, databases, and more, using a syntax similar to SQL queries. Integrating LINQ into Windows Forms and WPF applications can significantly enhance data querying and manipulation capabilities. In this article, we'll explore how to implement LINQ in both Windows Forms and WPF applications using C.

Windows Forms Applications:

Windows Forms is a popular framework for creating desktop applications in .NET. To implement LINQ in a Windows Forms application, follow these steps:

Add LINQ Namespace: Ensure that you have imported the LINQ namespace at the top of your code file:

WPF Applications:

WPF (Windows Presentation Foundation) is a powerful framework for building desktop applications with rich user interfaces. To implement LINQ in a WPF application, follow these steps:

Add LINQ Namespace: Similar to Windows Forms, ensure that you have imported the LINQ namespace:
