将ms访问的二进制文件转换为Imagelist的Image

我刚刚将位图缩略图转换为二进制代码,存储到我的MS Access数据库中。我现在正试图将二进制数据转换回图像格式,以存储到我的Imagelist中。我现在的代码是.

private void Form1_Load(object sender, EventArgs e)
    {
        vcon.Open();
        string get = "Select Path, Images FROM IMGSTR";
        OleDbCommand cmdget = new OleDbCommand(get, vcon);
        OleDbDataReader reader;
        reader = cmdget.ExecuteReader();
        while (reader.Read())
        {
            string path = reader["Path"].ToString();
            // should I convert binary into a string?
            string thumbnail = reader["Images"].ToString();
            // How to convert the binary data from the
            // MS database back to a bitmap image.
            //I need to convert the binary back to bitmap to work
            //in this imagelist.
            this.imageList1.Images.Add(thumbnail);
        }

    }

如果有人能帮助我那就太好了。谢谢

您需要将其强制转换为字节数组:

Image.FromStream(new MemoryStream((byte[]) reader["Images"]))
