How Can I Export Functions from a C# DLL?

Exporting Functions from a C# DLL: A Guide

In the realm of C development, the combination of "extern" and __declspec(dllexport) allows developers to effortlessly export functions from a DLL. This functionality enables external programs to access and utilize these functions. However, when venturing into the world of C# DLLs, a similar approach is required to achieve the same objective.

Unmanaged Exports

One possible solution is to leverage the UnmanagedExports NuGet package. This package modifies the intermediate language (IL) during compilation to incorporate the necessary exports for your functions. Armed with the [DllExport] attribute, you can adorn any static method, allowing it to be accessible from native code. The package seamlessly handles parameter and result marshalling with the aid of the MarshalAsAttribute, mimicking the functionality of DllImport.

DLLExport

Another option worth considering is the DLLExport project. This open-source library performs a similar task as UnmanagedExports. With its help, you can decorate your methods with the [DllExport] attribute, providing a straightforward mechanism for exporting functions from a C# DLL.

Loader DLL

In the specific context of Notepad add-ins, the exemplary C# implementation necessitates a loader DLL. This DLL serves as an intermediary, bridging the gap between Notepad and your C# functions. Its primary responsibility is to export and call the functions required by Notepad .

Conclusion

Whether your goal is to utilize UnmanagedExports, DLLExport, or employ a loader DLL, the ability to export functions from a C# DLL is at your disposal. These techniques empower C# developers to interact seamlessly with external applications, fostering interoperability and unlocking a realm of possibilities.
