Windows API declarations for C#

This is for C# programmers, not for QM. In QM can be used only in C# scripts.

Contains 48000 declarations of struct, enum, delegate, extern functions, interfaces, coclasses, Guid, const.

Converted commonly used Windows 10 SDK header files. The list is below.

Tools used to convert C to C#:
Quick Macros - scripting.
Clang - preprocessing.
Dumpbin from SDK - extracting dll names and GUID.
My C-to-C# converter project.

More declarations may be added in the future. Usually for me it is easy to do with these tools. Your suggestions are welcome.

How to use the downloaded file containing Windows API declarations:
// Don't add this file to your project. Copy-paste only declarations that you need.
// Not all declarations can be compiled without editing.
// For example, cannot declare some struct pointer (use IntPtr instead, or in struct replace non-blittable types with IntPtr etc), cannot use undefined struct pointer/ref/out (use IntPtr instead).
// Not all declarations are correct, usually because declarations in Windows SDK files from which they have been automatically converted lack some info.
// For example, some function parameters that should be 'out' or '[Out]' or '[In]' or array now are just 'ref', because SDK declarations didn't have proper in/out annotations. Also for this reason some parameters that should be 'string' now are 'StringBuilder'.
// You may want to create overloads where parameters can be of more than one type.
// You may want to add 'SetLastError=true' to DllImport attribute parameters.
// Some declarations contain pointers and therefore can be used only in 'unsafe' context, in some cases with 'fixed'. Or you can replace pointers to IntPtr.
// These declarations are for Windows 10. Some Windows API are different or missing on other Windows versions.
// In some cases need to use different declarations in 32-bit and 64-bit process. This file contains everything that is not different, + 64-bit versions, + 32-bit versions with name suffix ""__32"".



Also known as P/invoke, pinvoke, platform invoke signatures, call unmanaged dll exported methods, Win32 API, COM interop.

Could you give some simple examples how to use this Windows API in C#?

Warning: The code possibly is invalid because some important characters (tabs, spaces) disappeared. Read more.

Normally you'll use this in C# projects. To allow 'unsafe' keyword, in project Properties Build tab check 'Allow unsafe code'. Or remove the 'unsafe' keyword.

If want to run this as a QM C# script, remove the 'unsafe' keyword or use code 'CsScript x.SetOptions("compilerOptions=/unsafe"); x.Exec("")'. Also remove 'Console.ReadKey();'.

Thanks a lot for a thorough explanation.
I could compile and run it both as C# project and QM script.
Without your clarification and sample I have no clue how to get started on using this API stuff.
It really convenient to use C++ API in C# now.

Function SDK_find_declaration     ?
Trigger Cd     ?
;Finds a Windows API declaration in Api.cs.
;How to use:
;;;In your C# editor type a Windows API name, move the mouse over it and run this macro.
;;;Or move the mouse over a Windows API name anywhere, for example in API documentation.
;;;To run this macro you can use a hotkey trigger; default is Ctrl+D.
;;;The macro shows a dialog with the API name, its C# declaration (empty if not found) and several options.
;;;In the dialog review the declaration, maybe change options, and click OK.
;;;If you start this macro while it is already running, it replaces text in the dialog.
;;;Also you can edit text in the dialog Name field to search for a new name.
;How it works:
;;;Double-clicks to select word from mouse, and gets the word through the clipboard.
;;;Finds the declaration in Api.cs file and shows it in dialog together with options.
;;;Api.cs file full path must be specified in the dialog.
;;;The macro can copy the declaration to the clipboard or/and run a macro that for example can insert the declaration in a C# file. Example - function SDK_insert_declaration.
