how to save image file from stream?

[wastman]

 
Stream st;
FileStream f = new FileStream(@"D:\samp\rt.jpg", FileMode.Create);
byte[] b = new byte[10000];
 
st.Read(b, 0, b.Length);
 
st.Close();
f.Write(b, 0, b.Length);
f.Flush();
f.Close();
 

i doesn't show error.
but it gets noting stored.why?
but other files would be saved.but incase of image file,its happening thus.

FileStream Read

//Read image file 
byte[] b = null;
            using (FileStream f = new FileStream(@"C:\Bernese Oberland.jpg", FileMode.Open))
            {
                b = new byte[f.Length];
 
                f.Read(b, 0, b.Length);
            }
 
// Write to file ...
using (FileStream fs = new FileStream(@"C:\Bernese Oberland1.jpg", FileMode.Create))
            {
                fs.Write(b, 0, b.Length);
 
            }

No. stream is coming from webresponse.getStream() method.
so i need a solution for that one.

Well, there's probably an easier way, but if you wanted you could use the ReadByte method of the stream and add each byte you read to a System.Collectiosn.Generic.List<byte> until the byte you read is -1 (end of stream) and then convert the List into a byte[].

Lots of ways to do it though.

@insertAlias
but image does not get stored.should i follow something like sequential access?

[PRR]

Could you post more sample code? and maybe flow of your program...

Give me a solution,i don't want to waste my time though my name is wastman.

string s="http://c4.mobimgs.com/swarea/assets/ad56e59c/164446_scr.gif";
        try

                byte[] b = new byte[10000];
                st.Read(b, 0, b.Length);

Please get me out of a minor mistake which might be.

No.
The Actual Image:

but the output image:

so that i have got to guess if i have to check some thing like sequential access.

Please help me.

use this function

ArrayList addrs = new ArrayList();
 
addrs.Add("http://www.charlespetzold.com/key/keycs.jpg");
            addrs.Add("http://www.nbcindia.com/Booksimages/1931841306.gif");
 
 
int j = 0;
            foreach (string s in addrs)
            {
                try
                {                    
                    HttpWebRequest req = (HttpWebRequest)WebRequest.Create(s);
HttpWebResponse resp = (HttpWebResponse)req.GetResponse();
 
using (Stream st = resp.GetResponseStream())

I tried with 5-6 images ... almost all are "completely" saved ....
