[RESOLVED] How to get the size of a file if file is located on a sever

How can I get the size of a file in MB if the file is located on a server?

If the file is on a computer I would do this:

Code:

---

Dim file As New IO.FileInfo("c:\myfile.rar"))
label1.text = file.Length
' or: label1.text = (file.Length \ 1024) \ 1024 if i want the size in MB (i guess)

---

But what about if the file is located on:
http://www.mywebsite.com/myfile.rar

Thank you in advance,

Andrea.

Create a httpwebrequest and get a response object.
It has contentlength property.

Code:

---

  Dim wrq As HttpWebRequest = _
  DirectCast(WebRequest.Create("http://www.mywebsite.com/myfile.rar"), HttpWebRequest)

  Dim wrp As HttpWebResponse = _
  DirectCast(HttpWReq.GetResponse(), HttpWebResponse)

  MsgBox(String.Format("The file length is {0} bytes.", wrp.ContentLength)


  wrp.Close()

---

Note that in order for this to work the web-server has to be properly configured. In other words, it is not guaranteed that any server will fill in the necessary field.

The necessary classes are found in the System.Net namespace.

Thanks for the answer!
I thought there was an easier way to do that.
By the way, I cannot try the code beacause it gives me an error (I do have System.Net declared):

Code:

---

        DirectCast(HttpWReq.GetResponse(), HttpWebResponse) 'HttpWReq is not declared

---

If i try this:

Code:

---

DirectCast(HttpWebRequest.GetResponse(), HttpWebResponse) 'reference to a non-shared member requires an object reference

---

Any idea?

Thank you,

Andrea

it should have been wrq.GetResponse()

the error tells you that you can't access a non-shared member... means you need an instance to access it... that's what this means: requires an object reference

Wow thanks! it works!
Can you please tell me how I can convert the bytes in MB (eg. 137MB)?
I tried to do this but it gives me an error:

Code:

---

MsgBox(String.Format("The file length is {0} MB.", (wrp.ContentLength / 1024)) / 1024)

---

Thanks a lot again,

Andrea

my bad!


got it to work now:

Code:

---

MsgBox(String.Format("The file length is {0:0} MB.", ((wrp.ContentLength / 1024) / 1024)))

---

Thanks a lot guys! =D
