将新项目添加到 Visual Studio 工具箱的特定选项卡

Question

我创建了一个新的 Visual Studio 插件，用于在 Visual Studio 工具箱中创建和添加我的自定义选项卡，并将新项目（控件）添加到我的自定义选项卡。代码适用于向 Visual Studio 工具箱添加新选项卡，但不适用于向我的选项卡添加新项目（控件）。

我的 Visual Studio 插件代码是：

using System;
using Extensibility;
using EnvDTE;
using EnvDTE80;
using EnvDTE90;
using EnvDTE100;
using System.Windows.Forms;
namespace MyAddin1
{
    /// <summary>The object for implementing an Add-in.</summary>
    /// <seealso class='IDTExtensibility2' />
    public class Connect : IDTExtensibility2
    {
        /// <summary>Implements the constructor for the Add-in object. Place your initialization code within this method.</summary>
        public Connect()
        {
        }

        /// <summary>Implements the OnConnection method of the IDTExtensibility2 interface. Receives notification that the Add-in is being loaded.</summary>
        /// <param term='application'>Root object of the host application.</param>
        /// <param term='connectMode'>Describes how the Add-in is being loaded.</param>
        /// <param term='addInInst'>Object representing this Add-in.</param>
        /// <seealso class='IDTExtensibility2' />
        public void OnConnection(object application, ext_ConnectMode connectMode, object addInInst, ref Array custom)
        {
            _applicationObject = (DTE2)application;
            _addInInstance = (AddIn)addInInst;
            // Pass the applicationObject member variable to the code example.
            ToolboxExample(_applicationObject);
        }

        public void ToolboxExample(DTE2 dte)
        {
            ToolBox tlBox = null;
            ToolBoxTabs tbxTabs = null;
            ToolBoxTab3 tbxTab = null;
            try
            {
                tlBox = (ToolBox)(dte.Windows.Item(Constants.vsWindowKindToolbox).Object);
                tbxTabs = tlBox.ToolBoxTabs;
                tbxTab = (ToolBoxTab3)tbxTabs.Add("MRS");
                tbxTab.Activate();
                tbxTab.ToolBoxItems.Add("FloorsGrouping", @"C:\Windows\Microsoft.NET\assembly\GAC_MSIL\WindowsFormsControlLibrary2\v4.0_1.0.0.0__197889249da45bfc\WindowsFormsControlLibrary2.dll", vsToolBoxItemFormat.vsToolBoxItemFormatDotNETComponent);
            }
            catch (System.Exception ex)
            {
                MessageBox.Show("ERROR: " + ex.Message);
            }
        }

        private DTE2 _applicationObject;
        private AddIn _addInInstance;
    }
}

以下代码行不通：

tbxTab.ToolBoxItems.Add("FloorsGrouping", @"C:\Windows\Microsoft.NET\assembly\GAC_MSIL\WindowsFormsControlLibrary2\v4.0_1.0.0.0__197889249da45bfc\WindowsFormsControlLibrary2.dll", vsToolBoxItemFormat.vsToolBoxItemFormatDotNETComponent);

我变了

tbxTab.ToolBoxItems.Add

与：

tbxTabs.Item("MRS").ToolBoxItems.Add

但是，它对我不起作用。连我都变了

@"C:\Windows\Microsoft.NET\assembly\GAC_MSIL\WindowsFormsControlLibrary2\v4.0_1.0.0.0__197889249da45bfc\WindowsFormsControlLibrary2.dll"

使用以下代码行并一一测试：

@"E:\Rostami\Saino\WindowsFormsControlLibrary2.dll"

和

"WindowsFormsControlLibrary2.FloorsGrouping, WindowsFormsControlLibrary2, Version=1.0.0.0, Culture=neutral, PublicKeyToken=197889249da45bfc"

但是，它再次对我不起作用。

我的自定义控件主类名是FloorsGrouping，它的显示名是：

[DisplayName("Floors Group")]

它在 GAC 中的程序集名称是：

[Editor("WindowsFormsControlLibrary2.FloorsGrouping, WindowsFormsControlLibrary2, Version=1.0.0.0, Culture=neutral,  PublicKeyToken=197889249da45bfc", typeof(UITypeEditor))]

我在 Internet 上搜索了任何解决方案，但我只找到了几个解决方案，这些解决方案描述了向 Visual Studio 工具箱添加新选项卡以及通过 Visual Studio Addin 向选项卡添加控件。

Answer 1

我找到了解决方案，可以将自定义选项卡添加到 Visual Studio 工具箱，并将自定义控件添加到带有 Windows 窗体应用程序项目的自定义选项卡，而不是来自 Visual Studio 插件项目。我是这样描述的：

在 Windows Forms Application 项目中，首先，我们必须创建一个 Visual Studio IDE 的实例。然后，必须创建一个临时的 Windows 窗体应用程序项目，接下来，必须将我们的自定义选项卡添加到 Visual Studio 工具箱，并将我们的自定义控件添加到我们的自定义选项卡。

我的 Class1.cs 代码如下：
