在WPF中拖放文件传输。如何获取窗口中已删除内容的文件名

你的意思是文件的大小还是图像的像素大小? 无论如何,请使用以下代码:

private void Window_Drop(object sender, DragEventArgs e)
    {
        if (e.Data.GetDataPresent(DataFormats.FileDrop, true))
        {
            string[] droppedFilePaths = e.Data.GetData(DataFormats.FileDrop, true) as string[];
            foreach (var path in droppedFilePaths)
            {          
                string location = null;
                int pxWidth = 0, pxHeight = 0;

                FileInfo fi = new FileInfo(path);
                //fi.Length  //File size
                //fi.DirectoryName //Directory
                using (var fs = fi.OpenRead())
                {
                    try
                    {
                        var bmpFrame = BitmapFrame.Create(fs);
                        var m = bmpFrame.Metadata as BitmapMetadata;
                        if (m != null)
                            location = m.Location;
                        pxWidth = bmpFrame.PixelWidth;
                        pxHeight = bmpFrame.PixelHeight;
                    }
                    catch
                    {
                        //File isn't image
                    }
                }

                this.fileList.Items.Add(string.Format("({0}x{1}), location: {2}", pxWidth, pxHeight, location));
            }
        }
    }
