问题描述

Hello all，

我需要在may应用程序中使用C ++编写的几个本机dll结构：

 typedef struct _UF01_INFORMATIONS {
 BYTE Type [MAX_MODULE]; 
 BYTE Nombre_Module; 
 BYTE Nb_Voies [MAX_MODULE]; 
 BYTE Modele [MAX_MODULE]; 
 char *名称[MAX_MODULE]; 
 char *评论[MAX_MODULE]; 
 BOOL UseInterrupt; 
} UF01_INFORMATIONS，* PUF01_INFORMATIONS;

所以我写了这个：

 [System.Runtime。 InteropServices.DllImport（@"C：\Program Files（x86）\SELIAtec \ UF01 \ UF01.dll"，EntryPoint =" UF01_OpenDevices"，CallingConvention = System.Runtime.InteropServices.CallingConvention.StdCall）] 
 unsafe static extern Boolean UF01_OpenDevices（ref byte devices）; 
 
 [System.Runtime.InteropServices.DllImport（@"C：\Program Files（x86）\SELIAtec\UF01\UF01.dll"，EntryPoint =" UF01_CloseAll"，CallingConvention = System.Runtime.InteropServices.CallingConvention.StdCall）] 
 static extern void UF01_CloseAll（）; 
 
 [System.Runtime.InteropServices.DllImport（@"C：\Program Files（x86）\SELIAtec\UF01\UF01.dll"，EntryPoint =" UF01_UD01_8Entrees"，CallingConvention = System.Runtime.InteropServices.CallingConvention.StdCall）] 
 unsafe static extern Boolean UF01_UD01_8Entrees（byte device，byte module，ref byte data）; 
 
 [System.Runtime.InteropServices.DllImport（@"C：\Program Files（x86）\SELIAtec\UF01\UF01.dll"，EntryPoint =" UF01_UD01_8Entrees"，CallingConvention = System.Runtime.InteropServices.CallingConvention.StdCall）] 
 unsafe static extern Boolean UF01_GetInfosModule（byte Device，bool Watchdog，ref _UF01_INFORMATIONS uf01）; 
 
 public Form1（）
 {
 InitializeComponent（）; 
 
} 
 
 
 [StructLayout（LayoutKind.Sequential）] 
 public struct _UF01_INFORMATIONS 
 {
 [MarshalAs（UnmanagedType。 ByValArray，SizeConst = 8）] 
 public byte [] Type; 
公共字节Nombre_Module; 
 [MarshalAs（UnmanagedType.ByValArray，SizeConst = 8）] 
 public byte [] Nb_Voies; 
 [MarshalAs（UnmanagedType.ByValArray，SizeConst = 8）] 
 public byte [] Modele; 
 [MarshalAs（UnmanagedType.ByValArray，SizeConst = 8）] 
 public string [] Name; 
 [MarshalAs（UnmanagedType.ByValArray，SizeConst = 8）] 
 public string [] Comments; 
 public bool UseInterrupt; 
} 
 
 private unsafe void button1_Click（object sender，EventArgs e）
 {
 byte nb_Device = new byte（）; 
 
 _UF01_INFORMATIONS m_infos = new _UF01_INFORMATIONS（）; 
 m_infos.Type = new byte [8]; 
 m_infos.Nb_Voies = new byte [8]; 
 m_infos.Modele = new byte [8]; 
 m_infos.Name = new string [8]; 
 m_infos.Comments = new string [8]; 
 m_infos.Nombre_Module = new byte（）; 
 m_infos.UseInterrupt = false; 
 int iSize = Marshal.SizeOf（m_infos）; 
 
 
 if（UF01_OpenDevices（ref nb_Device））
 {
 this.label1.Text =" CPU数量：" + nb_Device; 
 
 if（UF01_GetInfosModule（nb_Device，false，ref m_infos））
 {
 // m_infos =（_ UF01_INFORMATIONS）（Marshal.PtrToStructure（uf01，typeof（_UF01_INFORMATIONS）））; 
 label2.Visible = true; 
 label2.Text =" NNumber of modules：" + m_infos.Nombre_Module; 
} 
 
} 
}

UF01_OpenDevices有效，但我错了

 if（UF01_GetInfosModule（nb_Device，false，ref m_infos））

有人能帮帮我吗？

Thanx：）

解决方案

Hello all,

I need to use several native dll struct written in C++ in may application :

typedef struct _UF01_INFORMATIONS{
        BYTE Type[MAX_MODULE];
        BYTE Nombre_Module;
        BYTE Nb_Voies[MAX_MODULE];
        BYTE Modele[MAX_MODULE];
        char *Name[MAX_MODULE];
        char *Comments[MAX_MODULE];
        BOOL UseInterrupt;
} UF01_INFORMATIONS, *PUF01_INFORMATIONS;

So I wrote this :

[System.Runtime.InteropServices.DllImport(@"C:\Program Files (x86)\SELIAtec\UF01\UF01.dll", EntryPoint = "UF01_OpenDevices", CallingConvention = System.Runtime.InteropServices.CallingConvention.StdCall)]
        unsafe static extern Boolean UF01_OpenDevices(ref byte devices);

        [System.Runtime.InteropServices.DllImport(@"C:\Program Files (x86)\SELIAtec\UF01\UF01.dll", EntryPoint = "UF01_CloseAll", CallingConvention = System.Runtime.InteropServices.CallingConvention.StdCall)]
        static extern void UF01_CloseAll();

        [System.Runtime.InteropServices.DllImport(@"C:\Program Files (x86)\SELIAtec\UF01\UF01.dll", EntryPoint = "UF01_UD01_8Entrees", CallingConvention = System.Runtime.InteropServices.CallingConvention.StdCall)]
        unsafe static extern Boolean UF01_UD01_8Entrees(byte Device, byte module, ref byte data);

        [System.Runtime.InteropServices.DllImport(@"C:\Program Files (x86)\SELIAtec\UF01\UF01.dll", EntryPoint = "UF01_UD01_8Entrees", CallingConvention = System.Runtime.InteropServices.CallingConvention.StdCall)]
        unsafe static extern Boolean UF01_GetInfosModule(byte Device, bool Watchdog, ref _UF01_INFORMATIONS uf01);

        public Form1()
        {
            InitializeComponent();

        }


        [StructLayout(LayoutKind.Sequential)]
        public struct _UF01_INFORMATIONS
        {
            [MarshalAs(UnmanagedType.ByValArray, SizeConst = 8)]
            public byte[] Type;
            public byte Nombre_Module;
            [MarshalAs(UnmanagedType.ByValArray, SizeConst = 8)]
            public byte[] Nb_Voies;
            [MarshalAs(UnmanagedType.ByValArray, SizeConst = 8)]
            public byte[] Modele;
            [MarshalAs(UnmanagedType.ByValArray, SizeConst = 8)]
            public string[] Name;
            [MarshalAs(UnmanagedType.ByValArray, SizeConst = 8)]
            public string[] Comments;
            public bool UseInterrupt;
        }      

        private unsafe void button1_Click(object sender, EventArgs e)
        {
            byte nb_Device= new byte();

            _UF01_INFORMATIONS m_infos = new _UF01_INFORMATIONS();
            m_infos.Type = new byte[8];
            m_infos.Nb_Voies = new byte[8];
            m_infos.Modele = new byte[8];
            m_infos.Name = new string[8];
            m_infos.Comments = new string[8];
            m_infos.Nombre_Module = new byte();
            m_infos.UseInterrupt = false;
            int iSize = Marshal.SizeOf(m_infos);


            if (UF01_OpenDevices(ref nb_Device))
            {
                this.label1.Text = "Number of CPU: " + nb_Device;

                if (UF01_GetInfosModule(nb_Device, false, ref m_infos))
                {
                    //m_infos = (_UF01_INFORMATIONS)(Marshal.PtrToStructure(uf01, typeof(_UF01_INFORMATIONS)));                    
                    label2.Visible = true;
                    label2.Text = "NNumber of modules : " + m_infos.Nombre_Module;
                }

            }
        }

The UF01_OpenDevices works but I get false with

if (UF01_GetInfosModule(nb_Device, false, ref m_infos))

Can someone help me please ?

Thanx :)
