本文介绍如何在WebBrowser控件的DocumentComplete事件中设置链接和表单目标为自身，以及通过调用系统API实现鼠标点击和键盘操作的模拟。提供了一个用于模拟左键点击和键盘按键的函数。

在webbrowser控件中的document complete 事件中设置链接到自身

        private void ieFrame_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
        {
            foreach (HtmlElement link in ieFrame.Document.Links)
            {
                link.SetAttribute("target", "_self");
            }

            foreach (HtmlElement form in ieFrame.Document.Forms)
            {
                form.SetAttribute("target", "_self");
            }
        }

使用下面封装完的函数模拟操作即可

#region 系统API申明区域
[DllImport("user32.dll")]
public static extern bool SetCursorPos(int x, int y);

        [Flags]
        public enum MouseEventFlag : uint
        {
            ABSOLUTE = 0x8000,
            MOVE = 0x0001,
            LEFTDOWN = 0x0002,
            LEFTUP = 0x0004,
            RIGHTDOWN = 0x0008,
            RIGHTUP = 0x0010,
            MIDDLEDOWN = 0x0020,
            MIDDLEUP = 0x0020,
            XDOWN = 0x0080,
            XUP = 0x0100,

        }

        {
            Point p = Control.MousePosition;
            SetCursorPos(x, y);
            mouse_event(MouseEventFlag.LEFTDOWN, 0, 0, 0, UIntPtr.Zero);
            mouse_event(MouseEventFlag.LEFTUP, 0, 0, 0, UIntPtr.Zero);
            SetCursorPos(p.X, p.Y);
        }

            keybd_event((byte)k, 0, 0x2, UIntPtr.Zero);
        }
