我正在尝试使用C#为Windows Mobile创建一个DLL,我有一个 我尝试在VC ++中访问DLL时出错。 可以在C#中创建DLL并使用Windows在VC ++中访问它 移动? 我正在使用Windows Mobile 6 SDK。 以下代码在Desktop中运行良好。

C#代码:

using System; 
using System.Collections.Generic; 
using System.Text; 
using System.Runtime.InteropServices; 
namespace HttpLibrary 
{ 
    [ComVisible(true)] 
    [StructLayout(LayoutKind.Sequential)] 
    public struct StorageGroup 
    { 
        public int count; 
        public string[] Name; 
        public string[] sgdName; 
        public string[] logfolder; 
        public string[] systemfolder; 
    } 
    [ComVisible(true)] 
    public struct MyResult 
    { 
        public string Name; 
    } 
    [ComVisible(true)] 
    [Guid("F55EDB71-E3FC-4FC2-A25B-6E09C49B3E93")] 
    public interface IMyClass1 
    { 
        int helloWorld(); 
        StorageGroup getStorageGroup(); 
    } 
    [ClassInterface(ClassInterfaceType.None)] 
    [Guid("7B0D798D-DD45-41E1-A0D4-2FC453B36CED")] 
    [ComVisible(true)] 
    public class Class1 : IMyClass1 
    { 
        public Class1() 
        { 
            //constructor.. create object.. 
        } 
        public int helloWorld() 
        { 
            //dont do anything just return 10 so that client can get 
the return value.. 
            return 10; 
        } 
        public MyResult helloWorld(int i) 
        { 
            MyResult result = new MyResult(); 
            result.Name = "jigar"; 
            return result; 
        } 
        public StorageGroup getStorageGroup() 
        { 
            //Put code here.. 
            StorageGroup sg = new StorageGroup(); 
            int count = 3; 
            sg.Name = new string[count]; 
            sg.sgdName = new string[count]; 
            sg.logfolder = new string[count]; 
            sg.systemfolder = new string[count]; 
            sg.count = count; 
            for (int i = 0; i 

The C++ code:

#import "c:\\pocket\\HTTP_POST_CS\\HttpLibrary\\HttpLibrary\\bin\\Debug \\HttpLibrary.tlb" BOOL CHttpLibraryTestDlg::OnInitDialog() { CDialog::OnInitDialog(); // Set the icon for this dialog. The framework does this automatically // when the application's main window is not a dialog SetIcon(m_hIcon, TRUE); // Set big icon SetIcon(m_hIcon, FALSE); // Set small icon CoInitializeEx(NULL, 0); HttpLibrary::IMyClass1Ptr pIMyClass1(__uuidof(HttpLibrary::Class1)); --->This line gives me a Raise Exception int i=-1; i = (int)pIMyClass1->helloWorld(); return TRUE; // return TRUE unless you set the focus to a control }

您不能在Compact Framework中执行此操作,因为它缺少CLR hosting功能。本机应用程序无法在其自己的进程中启动执行引擎,因此无法加载托管代码。这意味着您自己的本机应用程序无法加载托管DLL,也无法加载设备浏览器。
