Uploading files using ASP.NET problem

[darin dimitrov]

Hello,

I have the following Html form:

<form name="submitForProcess"
action="http://localhost/xml/process.aspx" method="post"
enctype="multipart/form-data">

<input type="text" name="customerId" value="5" /><br />
<input type="text" name="customerName" value="Johnson" /><br />
<input type="file" name="customerPhoto"><br />

<input type="submit" value="OK" />

</form>


In the ASP.NET page which is supposed to process this request I can
get the uploaded file name, length and content using the Request.Files
collection. Using the Request.Form collection I can get the
"customerId" and "customerName" parameters with their values.

My problem is that I cannot get the name attribute of my input file
tag which in this case is "customerPhoto". The Request.Form collection
doesn't contain this parameter. I am desperate, please help me, is it
possible to get this value using .NET classes ?


Here is the the dialog between the client and the server:

Hi,

My problem is that I cannot get the name attribute of my
input file tag which in this case is "customerPhoto".

Put this in your codebehind:

protected System.Web.UI.HtmlControls.HtmlInputFile customerPhoto;

when the user uploads a file, you can use this to get the name:

customerPhoto.PostedFile.FileName

Beware: it will return the full name on the client computer. You should use
Path.GetFileName(customerPhoto.PostedFile.FileName) to extract only the
filename.

Thanks very much for your post Hans,

I used the Request.Files.GetKey method to obtain the name of the attribute
