c# - Get Size of Image File before downloading from web

Question

I am downloading image files from web using the following code in my Console Application.

WebClient client = new WebClient();
client.DownloadFile(string address_of_image_file,string filename);

The code is running absolutely fine.

I want to know if there is a way i can get the size of this image file before I download it.

PS- Actually I have written code to make a crawler which moves around the site downloading image files. So I doesn't know its size beforehand. All I have is the complete path of file which has been extracted from the source of webpage.

Here is a simple example you can try if you have files of different extensions like .GIF, .JPG, etc you can create a variable or wrap the code within a Switch Case Statement

System.Net.WebClient client = new System.Net.WebClient();
client.OpenRead("http://someURL.com/Images/MyImage.jpg");
Int64 bytes_total= Convert.ToInt64(client.ResponseHeaders["Content-Length"])
MessageBox.Show(bytes_total.ToString() + " Bytes");
