C#调用c++ DLL
参数是一个链表指针,结构体这是C++ 的
struct HostList{
char ahost[16];

struct HostList *next; // Next HostList struct pointer
};
struct HostList * gpStructHostHeaderApp;
gpStructHostHeaderApp = HostHeader;
GetDataFromHMI(gpStructHostHeaderApp);
在C#是要调用 GetDataFromHMI(gpStructHostHeaderApp);
这个在C#中要怎样声明C++相同的结构和怎样调用并返回结构指针 --------------------编程问答-------------------- public class Pscollector

我这样调用以后 运行出现了 "尝试读取或写入受保护的内存。这通常指示其他内存已损坏。" 请问这个该怎么调用 --------------------编程问答--------------------

HostHeader 是什么 --------------------编程问答-------------------- GetDataFromHMI 函数 C++ 中返回值是什么？ --------------------编程问答--------------------
HostHeader就是结构体的头指针返回的也是这个指针 --------------------编程问答-------------------- GetDataFromHMI(gpStructHostHeaderApp);
没有返回值,要的数据就是HostHeader指针地址 --------------------编程问答-------------------- 感谢avphoenixi
结构体中的IntPtr next 指向空要怎样赋值,直接hostList.next = null 报错,调用时直接把结构传过去吗?
hostList.ahost = "192.168.0.250";
hostList.aport = "6666";
hostList.IsNeedconn = 1;
hostList.Connstate = 1;
hostList.GatherCycle = 5;
hostList.ReconnectCycle = 1;
hostList.ReconnectTimes = 1;
hostList.Type = 0;
hostList.GatherTime = 0;
hostList.next = null ;
Pscollector.GetDataFromHMI(ref hostList);
Pscollector.GetDataFromHMI(ref hostList)这句要怎样调用,不能用ref hostList报错 --------------------编程问答--------------------
[StructLayout(LayoutKind.Sequential)]--------------------编程问答-------------------- 非常感谢avphoenixi 这么详细的帮助我,现在运行时

运行到这里时出错提示
输出字节缓冲区太小，无法包含编码后的数据，编码“US-ASCII”的操作回退“System.Text.EncoderReplacementFallback”。
参数名: bytes --------------------编程问答-------------------- 运行到这名时
GetDataFromHMI(&hl);
出错提示
对 PInvoke 函数“MesCollector!MesCollector.Form1::GetDataFromHMI”的调用导致堆栈不对称。原因可能是托管的 PInvoke 签名与非托管的目标签名不匹配。请检查 PInvoke 签名的调用约定和参数与非托管的目标签名是否匹配。 --------------------编程问答-------------------- 在你的C++代码最外层，加上[assembly:CLSCompliant(true)] --------------------编程问答-------------------- 在你的C++代码最外层，加上[assembly:CLSCompliant(true)] --------------------编程问答-------------------- 调试一下，可能是C++代码里面有不符合cls规范的数据类型。GoodLuck！ --------------------编程问答-------------------- C++ dll 是别人做的,我们改不了,只给了一个在C++ 中调用这个dll的demo --------------------编程问答--------------------
这个问题，要了解端口传输的约定，是把端口作为字符串还是作为4字节整数？ 如果是字符串，端口是5位时就溢出，如果是整数，就改为这样
*((int*)hl.ahost) = 66666;--------------------编程问答-------------------- 调用 GetDataFromHMI(&hl);
这个后能不能直接访问h1结构中的数据,因为这个结构是个单链表 --------------------编程问答--------------------
函数声明时特性里加个设置
[DllImport("PsCollector.dll", EntryPoint = "GetDataFromHMI", CallingConvention= CallingConvention.Cdecl)]
unsafe extern static void GetDataFromHMI(HostList* hostlist);
--------------------编程问答--------------------
HostList* next = hl->next;
next->......
试试成员的值是否正常 --------------------编程问答-------------------- avphoenixi 您好
现在运行是没有错误,但取不到数据,能不能在textBox1中直接得到hl.data.
hl.data 怎样转成string --------------------编程问答--------------------
var data = new byte[5120];
Marshal.Copy((IntPtr)hl.values, data, 0, data.Length);
textBox1.Text = Encoding.ASCII.GetString(data);
这步就是转换，如果没值的话你看下上面几个成员赋的值对不对，如果有 C++ 调用代码贴上来看下 --------------------编程问答-------------------- // CollectorDemoDlg.cpp : implementation file
