Перевод с C/C++ на C#

Question

Я действительно застрял здесь. Надеюсь, кто-то может мне помочь. Как перевести эту функцию на C#?

void __declspec(dllexport) __cdecl test(float *avrSwap, int *aviFAIL, char *accInfile, char *avcOutname, char *avcMsg)

[DllImport("dllname", CallingConvention=CallingConvention.Cdecl, EntryPoint="test")] 
private static void Test(
    [In, Out, MarshalAs(UnmanagedType.LPArray, SizeConst=1024)] float[] avrSwap, 
    out int aviFAIL, 
    [In, MarshalAs(UnmanagedType.LPStr)] string accInfile, 
    [In, MarshalAs(UnmanagedType.LPStr)] string avcOutname, 
    [Out, MarshalAs(UnmanagedType.LPStr)], StringBuilder avcMsg 
); 

//Wrapper that correctly initializes the StringBuilder to its rightful size. 
//It's quite stupid that according to the P/Invoke help, 
//StringBuilder parameters don't support SizeConst. 
public static void WrapTest(float[] avrSwap, out int aviFAIL, string accInfile, string avcOutname, out string avcMsg) 
{ 
    StringBuilder sbAvcMsg = new StringBuilder(1024); 
    Test(avrSwap, out aviFail, accInfile, avcOutname, sbAvcMsg); 
    avcMsg = sbAvcMsg.ToString(); 
}
