Word文檔轉為Html文件

需要添加引用：

using System.IO;
using Word = Microsoft.Office.Interop.Word;（添加程序集引用）

 1        public static void Run()
        {
            DirectoryInfo dir = new DirectoryInfo("E:/20190917");
            FileInfo[] fileList = dir.GetFiles();//獲取指定文件夾下所有的文件
            //遍歷E:/20190917目錄下所有的Word文檔
            foreach (var item in fileList)
            {
                string ext = Path.GetExtension("E:/20190917/"+item.ToString());//獲取文件的后綴名
                string inputName ="E:/20190917/" + item.ToString();//獲取遍歷文檔的具體路勁
                string outputName = inputName.Replace(ext, ".html"); // 同路徑保存Html文檔
