Saving Image files in server after response

Anonymous User 2824 18 Dec 2014

My asp.net application saving a long list of image files and then have to view one of them. The client can browse the images, But its take a long time. I have a dictionary with key - file path and value -Image:

Dictionary<string, System.Drawing.Image> imageList = new Dictionary<string,System.Drawing.Image>(); 
//filling imageList 
foreach (KeyValuePair<imagePath, System.Drawing.Image> item in imageList)
{
    item.Value.Save(item.Key, System.Drawing.Imaging.ImageFormat.Jpeg);
}

I am looking for some way to save just one image file, make response, and continue saving the other image files, there is any way to do it? maybe with Thread? Thanks!

I put the images saving in thread block and it works perfectly and fast:

Dictionary<string, System.Drawing.Image> imageList =new Dictionary<string,System.Drawing.Image>(); 
//filling imageList 
Thread thread = new Thread(() =>{
   foreach(KeyValuePair<string, System.Drawing.Image> image in imageList)    {
       image.Value.Save(item.Key,System.Drawing.Imaging.ImageFormat.Jpeg);
    }
});
thread.Start();

Disk IO may be very slow, nevertheless you can try this

foreach (KeyValuePair<string, System.Drawing.Image> item in imageList)
    Task.Factory.StartNew(() =>
    {
        lock (item.Value)
            item.Value.Save(item.Key, System.Drawing.Imaging.ImageFormat.Jpeg);
    });
