I need to check for existence of a file on our website in "images"...

[trint]

How can I do this with my c# code with my website(because the file is
there, but the code doesn't return it)?:

if(File.Exists(String.Format("~/images/categories/{0}", sFileName))
return String.Format("~/images/categories/{0}", sFileName);
else if(File.Exists(String.Format("~/images/products/{0}",
sFileName))
return String.Format("~/images/products/{0}", sFileName);
else
return "";

I thought I might have to use:
Server.MapPath.

Any help is appreciated.
Thanks,
Trint

Trint,

Yes, you will have to use the MapPath method to get a path on the local
machine and then you can use the Exists method on the File class to check
the existence of it.

Hope this helps.

In your page, you can just do this:

// Get the url.
string url = String.Format("~/images/categories/{0}", sFileName);

// Check to see if the file exists on the server.
if (File.Exists(Server.MapPath(url)))
{
return url;
}
else
{
// Get the url.
url = String.Format("~/images/products/{0}", sFileName);

// Chefk for the existence.
if (File.Exists(Server.MapPath(url)))
{
// Return the url.
return url;
}

// Return an empty string.
return "";
}
