Question

所以我有这个方法来设置一些基本的MetaData标签，最终将添加到我的图像中：

        BitmapMetadata metaData = new BitmapMetadata("jpg");
        foreach (var t in tags)
        {
            try
            {
                switch (t.Key)
                {
                    case "Author":
                        metaData.Author = new System.Collections.ObjectModel.ReadOnlyCollection<string>(new string[] { t.Value });
                        break;

                    case "Rating":
                        int rating = 0;
                        if (int.TryParse(t.Value, out rating))
                        {
                            metaData.Rating = rating;
                        }
                        break;

                    case "Subject":
                        metaData.Subject = t.Value;
                        break;

                    case "Title":
                        metaData.Title = t.Value;
                        break;

                    case "Comment":
                        metaData.Comment = t.Value;
                        break;

                    default:
                        keywords.Add(string.Format("{0}:{1}", t.Key, t.Value));
                        break;
                }
            }
            catch (Exception ex)
            {
                //Do some logging
            }
        }

我一直收到错误：

System.NotSupportedException：没有适合的成像组件完成此操作被发现。 ---＆GT; System.Runtime.InteropServices.COMException：来自HRESULT的异常： 0x88982F50 \ ---内部异常堆栈跟踪结束--- \ at System.Windows.Media.Imaging.BitmapMetadata.SetQuery（String query，对象值）\ at System.Windows.Media.Imaging.BitmapMetadata.set_Title（String value）

在Windows 8.1上作为localhost运行，这很好用。一旦我将我的服务部署到我的Windows Server 2003 Web Edition，它就会抛出显示的错误。发生了什么事？

对此的修复是明确使用SetQuery作为元数据...... 例如：

BitmapMetadata jpgData = new BitmapMetadata("jpg");
jpgData.SetQuery("/app13/irb/8bimiptc/iptc/object name", "Test Title");
jpgData.SetQuery("/app13/irb/8bimiptc/iptc/keywords", "Test Tag");
jpgData.SetQuery("/app13/irb/8bimiptc/iptc/date created", "20090512");
jpgData.SetQuery("/app13/irb/8bimiptc/iptc/time created", "115300-0800");
jpgData.SetQuery("/app13/irb/8bimiptc/iptc/caption", "Test Comment");
jpgData.SetQuery("/app13/irb/8bimiptc/iptc/by-line", "Test Author");
jpgData.SetQuery("/app13/irb/8bimiptc/iptc/copyright notice", "Copyright 2009");

来自对this link的评论

这是因为Windows Server 2003中使用的WIC与Windows 7/8不同，无法更新。所以metadata.Title等throw notfoundexception

在Windows Server 2003 Web Edition上运行的服务中设置BitmapMetadata.Title会引发NotSupportedException
