我创建了一个新的Visual Studio Addin用于创建并在Visual Studio工具箱中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，但无法将新项目（控件）添加到我的选项卡。
我的Visual Studio Addin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;
}
}
以下代码行不起作用：
tbxTab.ToolBoxItems.Add("FloorsGrouping", @"C:\Windows\Microsoft.NET\assembly\GAC_MSIL\WindowsFormsControlLibrary2\v4.0_1.0.0.0__197889249da45bfc\WindowsFormsControlLibrary2.dll", vsToolBoxItemFormat.vsToolBoxItemFormatDotNETComponent);
我改变了
tbxTab.ToolBoxItems.Add
使用：
tbxTabs.Item("MRS").ToolBoxItems.Add
然而，它对我不起作用。即使我改变了
@"C:\Windows\Microsoft.NET\assembly\GAC_MSIL\WindowsFormsControlLibrary2\v4.0_1.0.0.0__197889249da45bfc\WindowsFormsControlLibrary2.dll"
使用以下代码行并逐个测试它们：
@"E:\Rostami\Saino\WindowsFormsControlLibrary2.dll"
和
"WindowsFormsControlLibrary2.FloorsGrouping, WindowsFormsControlLibrary2, Version=1.0.0.0, Culture=neutral, PublicKeyToken=197889249da45bfc"
然而，它再次对我不起作用。
我的自定义控件主类名称为 FloorsGrouping ，其显示名称为：
[DisplayName("Floors Group")]
其在GAC中的程序集名称是：
[Editor("WindowsFormsControlLibrary2.FloorsGrouping, WindowsFormsControlLibrary2, Version=1.0.0.0, Culture=neutral, PublicKeyToken=197889249da45bfc", typeof(UITypeEditor))]
我搜索了互联网上的任何解决方案，我只找到了几个解决方案，这些解决方案描述了向Visual Studio工具箱中添加新选项卡，并且可以从Visual Studio Addin添加控件到选项卡。
答案 0 :(得分：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使用Windows窗体应用程序项目的自定义选项卡，而不是从Visual Studio加载项项目。我将其描述如下：
在Windows窗体应用程序项目中，首先，我们必须创建一个Visual Studio IDE实例。然后，必须创建一个临时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。
