I want to add a file upload button to my web application in Visual Studio using C# in order to allow for the user to browse for a picture on his PC to save it in database. It is like when you want to attach file when you’re sending an email.
How can I add a file upload button to my website?
Something like
<form method="post" enctype="multipart/form-data" action="http://example.com">
<p>
Please specify a file:<br>
<input type="file" name="myfile">
</p>
<div><input type="submit" value="Send"></div>
</form>
In web application do you mean asp.net ?
If so, you can use File Upload control.
<asp:FileUpload ID="FileUpload1" runat="server" />
On client side add this to your form:
<asp:FileUpload ID="FileUpload1" runat="server" />
and on server side write this byte[] to a database field:
FileUpload1.FileBytes
use this
<input type="file" name="datafile" size="40">
indside a form.
You can find the basic information on HTML input tag over here. Working example
<asp:FileUpload ...if it's Asp.Net web forms(msdn.microsoft.com/en-us/library/…) beyond that can't help much more - you will need to provide more information. Oh yeah don't forgetenctype="multipart/form-data"on the enclosing form as @Widor's answer says
