            string path2 = CodePath + @"\kaowj\检查表拷贝到.xml";

          
            //初始化1
            FileInfo soufile = new FileInfo(path);
            //初始化2 
            FileInfo dest = new FileInfo(path2);

            try
            {
                //如果拷贝的路径有这个文件 就删除
                if (dest.Exists) dest.Delete();
                //执行拷贝到xx
                soufile.CopyTo(path2,true);
