Visual Studio 2015 插件开发 从入门到放弃（一）

古银有了个人博客了：小古银的官方网站

必需知识：C#和Visual Studio

（1）安装 Visual Studio 2015 的时候选择 Visual Studio 扩展性工具（Visual Studio Extensibility Tools）。对于已经安装好 Visual Studio 2015 的小伙伴，可以找VS2015的安装包，或者在程序与功能中找VS2015双击，在VS2015界面中选择修改，再选择Visual Studio 扩展性工具。



（2）安装完成后打开 VS2015，创建一个名为 FirstMenuCommand 的 VSIX Project：文件（File）->新建（New）->项目（Project）->Visual C#->Extensibility->VSIX Project，名称改为 FirstMenuCommand。





（3）工程打开后，添加一个名为 FirstCommand 的 custom command 模板：在 解决方案资源管理器（Solution Explorer）中，右键工程节点，选择添加（Add）->新建项（New Item）->Visual C# 项->Exitensibility->Custom Command，在 名称 中填入FirstCommand.cs。





（4）编译工程并且运行调试，将会出现一个调试用的 Visual Studio 出现。

（5）在用于调试的 Visual Studio 中，点击 工具（Tools）->扩展和更新（Extensions and Updates），在打开的窗口中就会找到FirstMenuCommand 插件。





（6）关闭扩展和更新窗口，在 工具（Tools）中会看到 Invoke FirstCommand 菜单命令。点击将会出现消息框，显示“FirstCommandPackage Inside FirstMenuCommand.FirstCommand.MenuItemCallback()”。





（7）停止调试。在原来的VS上打开 FirstCommand.cs 文件。添加  using 语句：

using System.Diagnostics;

（8）找到 FirstCommand 的私有构造方法，改成如下：

private FirstCommand(Package package)
{
if (package == null)
{
throw new ArgumentNullException("package");
}

this.package = package;

OleMenuCommandService commandService = this.ServiceProvider.GetService(typeof(IMenuCommandService)) as OleMenuCommandService;
if (commandService != null)
{
var menuCommandID = new CommandID(CommandSet, CommandId);

// 修改成StartNotepad句柄
MenuCommand menuItem = new MenuCommand(this.StartNotepad, menuCommandID);
commandService.AddCommand(menuItem);
}
}

（9）添加方法 StartNotepad ：

private void StartNotepad(object sender, EventArgs e)
{
Process process = new Process();
process.StartInfo.FileName = "notepad.exe";
process.Start();
}

（10）开始运行调试，点击 工具->Invoke FirstCommand ，将会弹出记事本程序。

FirstCommand.cs的全部代码：

using System;
using System.ComponentModel.Design;
using System.Globalization;
using Microsoft.VisualStudio.Shell;
using Microsoft.VisualStudio.Shell.Interop;
using System.Diagnostics; // 新增using语句

// 修改成StartNotepad句柄

commandService.AddCommand(menuItem);
}

private void MenuItemCallback(object sender, EventArgs e)
{
string message = string.Format(CultureInfo.CurrentCulture, "Inside {0}.MenuItemCallback()", this.GetType().FullName);
string title = "FirstCommand";

// Show a message box to prove we were here

this.ServiceProvider,
message,
title,
OLEMSGICON.OLEMSGICON_INFO,

// 新增StartNotepad方法用来打开记事本
private void StartNotepad(object sender, EventArgs e)
{
Process process = new Process();
process.StartInfo.FileName = "notepad.exe";
process.Start();
}
}
