This project contains various .NET assemblies that contain P/Invoke functions, interfaces, enums and structures from Windows libraries. Each assembly is associated with one or a few tightly related libraries. For example, Shlwapi.dll has all the exported functions from shlwapi.lib; Kernel32.dll has all for both kernel32.lib and kernelbase.lib.
All assemblies are available via NuGet and provide builds against .NET 4.8, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0, .NET Standard 2.0 & 2.1, Core 3.1 and support SourceLink. Extensions are available for WinForms, WPF, and UWP projects. If you need support for other .NET versions, look to versions 3.3.15 and earlier.
This project releases new versions every few weeks after sufficient testing. New releases are cataloged, along with release notes, in the Releases section and all NuGet packages are published to nuget.org. Each GitHub commit triggers a GitHub Actions build. The status of that build is in the header of this page. The NuGet packages from those pre-release builds are available for test purposes on MyGet's project NuGet source at https://www.myget.org/feed/Packages/vanara. There are details at that site for adding it as a NuGet Source.
Use
- Just include the Vanara.Library package which includes all the Vanara assembilies. Overkill, but easy.
-OR-
- Grab each library as needed:
- Look for the function you need in Microsoft documentation. Note which library or DLL the function is in.
- Confirm the Vanara library exists and has your function by looking at the Supported Libraries table below. Clicking on the Assembly link will take you to a drill down of that assembly's coverage. Find your function and if there is a matching implementation it will appear to the right. You can also use GitHub's project search (upper left of page) to search for your function, method or constant. Make sure to select "In this repository".
- Add the assembly to your project via NuGet.
- To use a function, you can:
- Call it directly
var bret = Vanara.PInvoke.Kernel32.GetComputerName(sb, ref sbSz); - Under C# 6.0 and later, use a static using directive and call it:
using static Vanara.PInvoke.Kernel32; var bret = GetComputerName(sb, ref sbSz); - Call it directly
- In some cases there is a corresponding helper/wrapper class in one of the Supporting Assemblies, especially for Security, System Services, Forms and Shell. Go to their library page (click on link in section) and look through the classes included in each library.
Design Concepts
- All functions that are imported from a single DLL should be placed into a single assembly that is named after the DLL.
- (e.g. The assembly
Vanara.PInvoke.Gdi32.dllhosts all functions and supporting enumerations, constants and structures that are exported fromgdi32.dllin the system directory.)
- (e.g. The assembly
- Any structure or macro or enumeration (no function) that is used by many libraries is put into either
Vanara.CoreorVanara.PInvoke.Shared.- (e.g. The macro
HIWORDand the structureSIZEare both inVanara.PInvoke.Sharedand classes to simplify interop calls and native memory management are inVanara.Core.)
- (e.g. The macro
- Inside a project, all constructs are contained in a file named after the header file (*.h) in which they are defined in the Windows API.
- (e.g. In the
Vanara.PInvoke.Kernel32project directory, you'll find a FileApi.cs, a WinBase.cs and a WinNT.cs file representing fileapi.h, winbase.h and winnt.h respectively.)
- (e.g. In the
- Where the direct interpretation of a structure or function leads to memory leaks or misuse, try to simplify its use.
- Where a structure is always passed by reference and where that structure needs to clean up memory allocations, change the structure to a class implementing
IDisposable. - Wherever possible, turn all handles into
SafeHandlederivatives named after the Windows API handle. If those handles require a call to a function to release/close/destroy, a derivedSafeHANDLEexists that performs that function on disposal.- e.g.
HTOKENis defined.SafeHTOKENbuilds upon that handle with an automated release callingCloseHandle.
- e.g.
- Wherever possible, all functions that allocate memory that is to be freed by the caller use a safe memory handle.
- All PInvoke calls are in assemblies prefixed by
Vanara.PInvoke. - If a structure is to passed into a function as a constant, that structure is marshaled using the
instatement which will pass the structure by reference without requiring therefkeyword.- Windows API:
BOOL MapDialogRect(HWND hDlg, LPRECT lpRect) - Vanara:
bool MapDialogRect(HWND hDlg, in RECT lpRect);
- Windows API:
- If there are classes or extensions that make use of the PInvoke calls, they are in wrapper assemblies prefixed by
Vanaraand then followed by a logical name for the functionality. Today, those are Core, Security, SystemServices, Windows.Forms and Windows.Shell. - Functions use overloads, and often generated overloads, to simplify the call (allocating and releasing memory, handling pointers, templating complex patterns, etc.). When calling a method, check to see if there is an overload first.
