Can C# Applications Integrate and Utilize C Libraries (e.g., RakNet)?

Integrate C code in C# applications

This article explores how to call C code in a C# program, especially when compiled into a library file (.dll), focusing on how to integrate a C library like RakNet.

Answer:

It is completely possible to integrate C code into C#. An efficient approach is to create a wrapper assembly using C/CLI. This hybrid language allows seamless interaction with unmanaged C code while allowing C/CLI code to be seamlessly called from C#.

For example, a C/CLI code snippet can be compiled using the /clr switch:

<code class="language-cpp">#include "NativeType.h"

public ref class ManagedType
{
    NativeType*   NativePtr;

public:
    ManagedType() : NativePtr(new NativeType()) {}
    ~ManagedType() { delete NativePtr; }

    void ManagedMethod()
    { NativePtr->NativeMethod(); }
};</code>

In C#, you can add a reference to the ManagedType assembly and use it as follows:

<code class="language-csharp">ManagedType mt = new ManagedType();
mt.ManagedMethod();</code>
