Ｃ#操控word和ＩＥ实现上传文章

场景：

ＯＡ系统用了在线office插件，只能用ＩＥ浏览器，打开网页时显示在线版word,但是用Ｆ12开发工具看取不到元素。用chrome浏览器无法操作。

手工上传文件的做法是：在电脑上打开word文章，CTRL+Ａ全选，CTRL+C复制；然后打开网页，CTRL+V粘贴。

另外，网页上还有input和submit元素，好在这两个元素可以用开发工具选取和提交。

思路：Ｃ#读取word,全选并复制到剪贴板，关闭word;用SHDocVw.InternetExplorer打开ＩＥ，打开后焦点在网页word控件中，发送CTRL+V；再填写input和submit提交。

代码： 

        private void 发稿件ToolStripMenuItem_Click(object sender, EventArgs e)
        {
            this.WindowState = FormWindowState.Minimized;
            //打开word文件所在目录
            //获得该文件夹下的文件，返回类型为FileInfo

            string path = @"I:\mynews";
            DirectoryInfo root = new DirectoryInfo(path);
            FileInfo[] files = root.GetFiles();

            Microsoft.Office.Interop.Word.Application app = new Microsoft.Office.Interop.Word.Application();
            object fname = files[0].FullName;
            string fnamestr = files[0].Name;
            var doc = app.Documents.Open(ref fname);
            Range range = doc.Range();//如果Range()不传入实参，则表示获取整个Document范围的Range
            range.Copy();
            doc.Close();
            app.Quit();
            app = null;
            System.Threading.Thread.Sleep(300);
            //流程－发文－切换文档类型word
            SHDocVw.InternetExplorer IE = new SHDocVw.InternetExplorer();
            object Empty = 0;
            object URL = "http://192.168.132.80/docs/docs/DocAddExt.jsp?mainid=15&secid=1143&subid=49&topage=&showsubmit=1&prjid=&coworkid=&crmid=&hrmid=&docType=.doc&docsubject=&from=&userCategory=0&invalidationdate=";
            IE.Visible = true;
            IE.Navigate2(ref URL, ref Empty, ref Empty, ref Empty, ref Empty);
            System.Threading.Thread.Sleep(10000);
            //System.Windows.Forms.SendKeys.Send("^v");//这个命令似乎会导致焦点切换，不可靠。
            KeyBordClick kc = new KeyBordClick();
            kc.KeyBordPaste();
            //填入文件名
            fnamestr = fnamestr.Replace(".docx", "");
            fnamestr = fnamestr.Replace(".doc", "");
            ((IE.Document as mshtml.HTMLDocument).getElementById("docsubject") as mshtml.HTMLInputElement).value = fnamestr;
            System.Threading.Thread.Sleep(1000);
            //找提交按钮
            var btnts = (IE.Document as mshtml.HTMLDocument).getElementsByTagName("button");
            foreach (mshtml.HTMLButtonElement btnt in btnts)
            {
                if (btnt.innerText == "保存到服务器")
                {
                    btnt.click();
                    files[0].Delete();
                    break;
                }

            }
  
        }

    class KeyBordClick
    {
        [DllImport("user32.dll", EntryPoint = "keybd_event", SetLastError = true)]
        private static extern void keybd_event(Keys bVk, byte bScan, uint dwFlags, uint dwExtraInfo);
        const int KEYEVENTF_KEYUP = 0x02;
        const int KEYEVENTF_KEYDOWN = 0x00;

        //相当于按下ctrl+v，然后回车
        public void KeyBordPaste()
        {
            keybd_event(Keys.ControlKey, 0, KEYEVENTF_KEYDOWN, 0);
            keybd_event(Keys.V, 0, 0, 0);
            keybd_event(Keys.ControlKey, 0, KEYEVENTF_KEYUP, 0);
            keybd_event(Keys.Enter, 0, 0, 0);
        }
    }
