问题描述

如何从Microsoft Access数据库添加和检索图像，以及如何使用C#WinForms检索它们?

How can I add and retrieve images from Microsoft Access database and also retrieve them using C# WinForms?

推荐答案

将图像转换为byte []并插入类型为image的列中. 虽然检索检查不为null，然后从数据读取器中读取并类型转换为byte [].

Convert image into byte[] and insert into column of type image. While retrieve check is not null and then read from datareader and typecast into byte[].

 if (dr["Image"] != DBNull.Value && dr["Image"] != null)
                            {
                                Image = (byte[])dr["Image"];
                            } 

从byte []您可以转换为图像

From byte[] you can convert into image

Image img;
Image.FromStream(new MemoryStream(m_Image));
