如何在byte [] c＃中保存位圖？

Question

我需要保存bitmap在byte[]與C＃，如何做到這一點？此

Answer 1

工作的代碼是

System.Drawing.Image originalImage = dpgraphic.image;// replace your image here i.e image bitmap 
//Create empty bitmap image of original size 
float width=0, height=0; 
Bitmap tempBmp = new Bitmap((int)width, (int)height); 
Graphics g = Graphics.FromImage(tempBmp); 
//draw the original image on tempBmp 
g.DrawImage(originalImage, 0, 0, width, height); 
//dispose originalImage and Graphics so the file is now free 
g.Dispose(); 
originalImage.Dispose(); 
using (MemoryStream ms = new MemoryStream()) 
{ 
    // Convert Image to byte[] 
    tempBmp.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg); 
    //dpgraphic.image.Save(ms, System.Drawing.Imaging.ImageFormat.Bmp); 
    byte[] imageBytes = ms.ToArray(); 
}

看看從MSDN http://msdn.microsoft.com/en-us/library/system.drawing.imaging.bitmapdata.aspx這個示例中，我希望你正在尋找這一點。

Answer 3

怎麼樣

在

YourByteArray = System.IO.File.ReadAllBytes("YourGraphic.bmp"); 

讀寫出來

System.IO.File.WriteAllBytes("SaveToFile.bmp", YourByteArray); 

作品對我來說
