求助一个关于asp.netWord加水印的问题

Question

                                if ( extentionName == "doc" || extentionName == "docx")
                                {
                                    //新建一个word文档对象，加载待添加水印的word文档
                                    Document doc = new Document();
                                    doc.LoadFromFile(Server.MapPath("/UploadFile/DescriptionWE/" + setname));
                                    //新建一个图片水印对象并添加待设置为水印的图片
                                    PictureWatermark picture = new PictureWatermark();
                                    picture.Picture = System.Drawing.Image.FromFile(Server.MapPath("/skin/images/water.png"));
                                    //根据需要设置图片的大小，然后将其设置为文档的水印
                                    picture.Scaling = 80;
                                    doc.Watermark = picture;
                                    //保存文本
                                    doc.SaveToFile(Server.MapPath("~/UploadFile/DescriptionWE/") + PFDname);
                                    doc.Close();
                                    if (IsEdit)
                                    {
                                        if (!string.IsNullOrEmpty(Article.FileUpload))
                                        {
                                            DeleteFileHelp.DeleteFile("~/UploadFile/DescriptionWE/" + Article.FileUpload);
                                        }
                                    }
                                    Article.FileUpload = PFDname;
                                }

上面是我asp.netWord加水印的代码，走到PictureWatermark picture = new PictureWatermark();就停止了，是不是System.Drawing.Image.FromFile()里面我的路径写错了，请各位帮忙指正下，感谢

Answer 1

string s = Server.MapPath("/skin/images/water.png");
然后输出下s或者下断点，看下s的值是多少。
