Question

我正在使用c ++形态库mcr.dll，当我在C＃控制台应用程序中使用它时它工作正常，但当我试图在ASP.NET MVC4控制器中运行此代码时它失败了＃34; getlemma（）＆＃34;方法，在线＆＃34; LoadMcr（s）＆＃34;使用System.StackOverflowException。请帮助我理解，为什么mvc控制器不想让它像在控制台应用程序中那样工作？

PS：当我尝试在控制台应用程序中运行它时出现了一些问题，例如关于＆＃34; PInvoke＆＃34; ConsoleApplication1！ConsoleApplication1.morph :: LoadMc unbalanced stack＆＃34;的消息，但是当我添加"CallingConvention = CallingConvention.Cdecl".

时，它们就消失了

public string getlemma(string word)
    {
        InitMcr();
        string s = "zal.mcr";
        LoadMcr(s);
        Tids tt = new Tids();
        FindWID(word, ref tt);
        Tid t = tt.ids[0];
        Tinlexdata inlex = new Tinlexdata();
        GetWordById(t, false, false, ref inlex);
        return (inlex.inlex[0].anword);
    }
    [System.Runtime.InteropServices.StructLayoutAttribute(System.Runtime.InteropServices.LayoutKind.Sequential)]
    public struct Tid
    {
        /// unsigned int
        public uint lnk;

        /// unsigned char
        public byte en;
    }
    [System.Runtime.InteropServices.StructLayoutAttribute(System.Runtime.InteropServices.LayoutKind.Sequential)]

        public int count;
    }
    // // InitMcr() - initialize dictionary 

    [DllImport("mcr.dll", CharSet = CharSet.None, CallingConvention = CallingConvention.Cdecl)]
    public static extern int InitMcr();

    public static extern int FindWID([System.Runtime.InteropServices.InAttribute()] [System.Runtime.InteropServices.MarshalAsAttribute(System.Runtime.InteropServices.UnmanagedType.LPStr)] string s, ref Tids ids);

    // GetByID - (get lemma for a word) 
    [DllImport("mcr.dll", CharSet = CharSet.None, EntryPoint = "GetWordById", CallingConvention = CallingConvention.Cdecl)]
