將二進制從ms訪問轉換爲Imagelist的圖像

Question

我剛剛將位圖縮略圖轉換爲二進制代碼以存儲到我的MS Access數據庫中。我現在試圖將該二進制數據轉換回圖像格式存儲到我的Imagelist中。我現在的代碼是。

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); 

     } 



    } 

如果有人可以幫助我，將是巨大的。謝謝！

您需要將其轉換爲字節數組：

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