以下代码，好像对于有嵌套行为的页面，无效，不过略作修改应该也能兼容所有情况：

using System;
    using System.Collections.Generic;
    using System.ComponentModel;
    using System.Data;
    using System.Drawing;
    using System.Text;
    using System.Windows.Forms;
    
    namespace localindex
    {
        public partial class Form1 : Form
        {
            public Form1()
            {
                InitializeComponent();
            }
    
            private void Form1_Load(object sender, EventArgs e)
            {
                webBrowser1.ScriptErrorsSuppressed = true; //禁用错误脚本提示
                webBrowser1.IsWebBrowserContextMenuEnabled = false; // 禁用右键菜单
                webBrowser1.WebBrowserShortcutsEnabled = false; //禁用快捷键
                webBrowser1.AllowWebBrowserDrop = false; // 禁止文件拖动
    
                webBrowser1.Navigate(Application.StartupPath + @"\assets\index.html");
                webBrowser1.Document.Window.Error += Window_Error;
                webBrowser1.NewWindow += CancelEventHandler;
                webBrowser1.DocumentCompleted += webBrowser_DocumentCompleted;
            }
    
            private void webBrowser_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
            {
                foreach (HtmlElement archor in webBrowser1.Document.Links)
                {
                    archor.SetAttribute("target", "_self");
                }
    
                foreach (HtmlElement form in webBrowser1.Document.Forms)
                {
                    form.SetAttribute("target", "_self");
                }
            }
    
            private void Window_Error(object sender, HtmlElementErrorEventArgs e)
            {
                e.Handled = true;
            }
    
            //禁用新窗口打开
            public void CancelEventHandler(object sender, CancelEventArgs e)
            {
                //webBrowser1.StatusText 判断是否是url类
                //System.Diagnostics.Process.Start(webBrowser1.StatusText);
                e.Cancel = true;
            }
        }
    }

webBrowser\_DocumentCompleted里面讲页面调转的地方全部修改了标签模式。注意，CancelEventHandler中需要将e.Cancel = true;进行设置
