我刚刚将位图缩略图转换为二进制代码以存储到我的MS Access数据库中。我现在正在尝试将二进制数据转换回图像格式以存储到我的Imagelist中。我的代码现在是。
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会很棒。谢谢!

您需要将其强制转换为字节数组:
Image.FromStream(new MemoryStream((byte[]) reader["Images"]))
