以编程方式监视在visual studio中打开的选项卡。

using System;
using EnvDTE;
using EnvDTE80;

public class TabMonitor
{
    private DTE2 _dte;

    public TabMonitor(DTE2 dte)
    {
        _dte = dte;
        _dte.Events.WindowEvents.WindowActivated += OnWindowActivated;
    }

    private void OnWindowActivated(Window gotFocus, Window lostFocus)
    {
        if (gotFocus.Document != null)
        {
            string documentName = gotFocus.Document.FullName;
            string documentLanguage = gotFocus.Document.Language;

            // 在这里可以对打开的选项卡进行监视和处理
            Console.WriteLine("当前打开的选项卡：");
            Console.WriteLine("文件名：" + documentName);
            Console.WriteLine("语言：" + documentLanguage);
        }
    }
}
