How to use the Windows API easily from C#

Simple-WinAPI-Wrapper is an open source .NET library that allows us to interact with the Windows API easily from a C# application.

WinAPI is an application programming interface for Windows operating systems. It provides a way to interact with the operating system and control the behavior of applications.

Thanks to the Windows API, we can perform complex tasks that would be difficult or impossible to do otherwise. For example, we can search for a window, move it, maximize it, control the mouse, or emulate keyboard events.

However, using WinAPI can be tedious and error-prone. Simple-WinAPI-Wrapper is an open source project that offers a simple and easy-to-use interface for the Windows API.

Some of its features are,

  • Ease of use: it provides an easy-to-use interface that simplifies the use of the Windows API.
  • Consistency: All Windows API functions are wrapped in a coherent and consistent interface that makes using the API easier and less error-prone.
  • Compatibility: it is compatible with all modern versions of Windows and .NET.

How to use Simple WinAPI Wrapper

We can easily add the library to a .NET project through the corresponding Nuget package.

Install-Package simple-winapi-wrapper

Here are some examples of how to use Simple-WinAPI-Wrapper extracted from the library’s documentation


var windows = WindowSearch.GetAllWindowsByProcess("notepad", false);

foreach (var window in windows)
    Console.WriteLine($"{window.GetTitle()} - {window.GetClass()}");

var mainWindow = windows.FirstOrDefault(x => x.GetClass().ToLower() == "notepad");


Keyboard.Type("hello, hello, hello how are you", 5);

Simple-WinAPI-Wrapper is Open Source, and all the code and documentation is available in the project’s repository at
