使用COM Interop的依赖项注册程序集

Question

提前抱歉所有代码......

我正在尝试创建一个名为＆＃34; CliParser＆＃34;的Visual Studio自定义工具，并且有一段艰难时期。在我的VS解决方案中，我有一个名为CliParser的项目依赖于名为Danware.COM的项目。 Danware.COM处理将COM类注册为VS自定义工具的样板，其中包含一个名为VsSingleFileGenerator的抽象类和一个名为VsCustomToolAttribute的属性。然后，CliParser定义了一个名为CliParser的类，它继承VsSingleFileGenerator并具有[VsCustomTool]属性。这两个项目都已经签署，并且已经注册了COM Interop＆＃34;已检查属性，并且正在定位＆＃34;任何CPU＆＃34;。构建成功完成，没有任何COM注册错误。

然而，我无法在任何COM客户端找到CliParser！ Visual Studio和MS Excel都不会在“添加引用”菜单中显示它。即使我手动运行regasm.exe / tlb（32- 或 64位版本），它也表示所有内容都已成功导出/注册，但引用不会出现在这些COM客户端中。如何能够毫无错误地构建/注册所有内容，但实际的COM类型是不可用的？我可以想象的是，我正在将这个继承层次结构拆分为汇编。所有相关代码如下所示。如果有人能发现我错过的东西，我将非常感激

以下是VsSingleFileGenerator：

using System;
using System.Runtime.InteropServices;

using Microsoft.Win32;
using Microsoft.VisualStudio.Shell.Interop;

namespace Danware.COM {

    [ComVisible(true)]
    [Guid("A298E59F-2B16-4E2F-A5CC-61FE4B7CA676")]
    public abstract class VsSingleFileGenerator : IVsSingleFileGenerator {

        public abstract int DefaultExtension(out string pbstrDefaultExtension);
        public abstract int Generate(string wszInputFilePath, string bstrInputFileContents, string wszDefaultNamespace, IntPtr[] rgbOutputFileContents, out uint pcbOutput, IVsGeneratorProgress pGenerateProgress);

        [ComRegisterFunction]
        private static void RegisterClass(Type t) {
            var ga = t.GetCustomAttribute<GuidAttribute>(true);
            var cta = t.GetCustomAttribute<VsCustomToolAttribute>(true);
            string keyName = getKeyName(cta.LanguageGuid, cta.Name);
            using (RegistryKey key = Registry.LocalMachine.CreateSubKey(keyName)) {
                key.SetValue("", cta.Description);
                key.SetValue("CLSID", $"{{{ga.Value}}}");
                key.SetValue("GeneratesDesignTimeSource", 1);
            }
        }

        [ComUnregisterFunction]
        private static void UnregisterClass(Type t) {
            var cta = t.GetCustomAttribute<VsCustomToolAttribute>(true);
            string keyName = getKeyName(cta.LanguageGuid, cta.Name);
            Registry.LocalMachine.DeleteSubKey(keyName, false);
        }

        private static string getKeyName(string languageGuid, string customToolName) {
            return $"SOFTWARE\\Microsoft\\VisualStudio\\14.0\\Generators\\{{{languageGuid}}}\\{customToolName}\\";
        }

    }

}

以下是VsCustomToolAttribute：

using System;
using System.Collections.Generic;

namespace Danware.COM {

    public enum VsLanguage {
        CSharp,
    }

    [AttributeUsage(AttributeTargets.Class, AllowMultiple = false, Inherited = false)]
    public class VsCustomToolAttribute : Attribute {

        private IDictionary<VsLanguage, string> _langGuids = new Dictionary<VsLanguage,string>() {
            { VsLanguage.CSharp, "FAE04EC1-301F-11D3-BF4B-00C04F79EFBC" },
        };

        public VsCustomToolAttribute(string name) : 
            this(name, VsLanguage.CSharp, "") { }

        public VsCustomToolAttribute(string name, string description) :
            this(name, VsLanguage.CSharp, description)
        {
            Name = name;
            Description = description;
        }

        public VsCustomToolAttribute(string name, VsLanguage language, string description) {
            Name = name;
            LanguageGuid = _langGuids[language];
            Description = description;
        }

        public string Name { get; }

        public string LanguageGuid { get; }

        public string Description { get; }
    }

}

这是CliParser：

using System;
using System.Text;
using System.Windows.Forms;
using System.Runtime.InteropServices;

using Danware.COM;

using Microsoft.VisualStudio;
using Microsoft.VisualStudio.Shell.Interop;

namespace CliParser {

    [ComVisible(true)]
    [Guid("F4BA90DA-E459-4889-8E14-AF27FC7437DC")]
    [VsCustomTool("CliParser", "Generates a strongly typed class to faciliate implementating a command line interface")]
    public class CliParser : VsSingleFileGenerator {

        public override int DefaultExtension(out string pbstrDefaultExtension) {
            pbstrDefaultExtension = ".txt";
            return pbstrDefaultExtension.Length;
        }
        public override int Generate(string wszInputFilePath, string bstrInputFileContents, string wszDefaultNamespace, IntPtr[] rgbOutputFileContents, out uint pcbOutput, IVsGeneratorProgress pGenerateProgress) {
            try {
                byte[] bytes = Encoding.UTF8.GetBytes("OMG did we actually make it??");
                int length = bytes.Length;
                rgbOutputFileContents[0] = Marshal.AllocCoTaskMem(length);
                Marshal.Copy(bytes, 0, rgbOutputFileContents[0], length);
                pcbOutput = (uint)length;
            }
            catch (Exception ex) {
                MessageBox.Show(ex.ToString());
                pcbOutput = 0;
            }
            return VSConstants.S_OK;
        }

    }

}
