# multiplatform

[peter Qin]

why kotin multiplatform project can generate dll file，but in windows c# project cannot be imported? Can someone help me，thanks a lot

in build.gradle config like this :

mingwX64(“native”)*{*
binaries*{*
sharedLib {
baseName = “libnative”
}
}
}

Hey off the bat I will say my knowledge on this is limited but I wanted to throw out the fact that the DLL internal format may be different. Have you tried this with a C++ or C application , prefereably also using mingw?

Do you want to call C# DLL from a Kotlin project? Have you developed any C++ program that calls a C# dll? You may have used C++/CLI or C++/CX (not a plain C++), because you should embed .NET runtime (or Mono) to your C++ project to call a C# dll. As in C++, you should also embed .NET or Mono in your Kotlin application.

If you want to interop C# and Kotlin, calling Kotlin from C# would be much easier.

If you want to call Kotlin from C#, the following code should work:

[DllImport("libnative.dll")]
static extern IntPtr /* or a pointer to a struct */ libnative_symbols();

@Bernat I've just seen the message, sorry for the late reply. I've also just found that Kotlin does not generate indexers for arrays. How about defining a helper function like this?

fun arrayGet(array: Array<Any>, idx: Int) = array[idx]
fun arraySet(array: Array<Any>, idx: Int, value: Any) {
    array[idx] = value
}
