c# - 显示检索为 ravendb 附件的图像

Question

简单问题：如何在winforms pictureBox 中显示检索到的ravendb 附件图像。

附件检索为

Raven.Abstractions.Data.Attachment attachment =
                        _store.DatabaseCommands.GetAttachment("upload/"+ 9999);

更新

像这样用放置附件保存图像

 _Store.DatabaseCommands.PutAttachment("upload/" + attachId, null, ms,
                                            new RavenJObject
                                                {
                                                   { "Content-Type", "image/jpeg" }

                                                });

ms 是内存流

Answer 1

您需要从Attachment对象中检索附件内存流：

pictureBox1.Image = Image.FromStream(attachment.Data());
