ImageResizer 源参数未被接受

Question

我正在尝试循环浏览文件夹中的 jpeg 图像，并使用以下方法将其提供给 dll，但它抛出了这个错误 Source 只能是字符串、VirtualFile、IVirtualBitmapFile、HttpPostedFile、HttpPostedFileBase、Bitmap、Image 或 Stream 的一个实例。参数名称：source

 foreach(FileInfo file in tempFolder.GetFiles())
        if (file.Exists == true)
        { //Skip unused file controls.

            //The resizing settings can specify any of 30 commands.. See http://imageresizing.net for details.
            //Destination paths can have variables like <guid> and <ext>, or 
            //even a santizied version of the original filename, like <filename:A-Za-z0-9>
            ImageResizer.ImageJob i = new ImageResizer.ImageJob(file, uploadFolder + "/<guid>.<ext>", new ImageResizer.ResizeSettings(
                        "width=2000;height=2000;format=jpg;mode=max"));
            i.CreateParentDirectory = true; //Auto-create the uploads directory.
            i.Build();
        }
        browser.Attributes["multiple"] = "multiple";
        Page.Response.Redirect(Page.Request.Url.ToString(), true);
    }

ImageRsizer.ImageJob 接受文件路径作为参数。您不需要提供 FileInfo 对象，而是需要传递它的 FullName 属性。即：

ImageResizer.ImageJob i = new ImageResizer.ImageJob(file.FullName, uploadFolder + "/<guid>.<ext>", new ImageResizer.ResizeSettings(
                    "width=2000;height=2000;format=jpg;mode=max"));
