Multiple objects in a using statement?

[tshad]

I tried to put multiple objects in one using statements like so:

using (fs = new FileStream(from ImagePath + "\\" +
(string)dr["originalFileNa me"],
FileMode.Open, System.IO.FileA ccess.Read) , BinaryReader br = new
BinaryReader(fs ))

But I get an error:

") expected"

Where the "," before the BinaryReader is.

Plus some "; missing" messages.

But this is how MSDN says to do it.

What am I missing here?

Thanks,

Tom

You can only declare multiple variables in one using statement if
they're of the same type. However, you can nest using statements
without using extra braces:

using (FileStream fs = ...)
using (BinaryReader br = ...)
{
// Use br here
}
