Need to close FileStream

[tshad]

If I have the following:

fs = new FileStream(xmlFile, FileMode.Open,
System.IO.FileAccess.Read);
sr = new StreamReader(fs);

will sr.Close() also close the fs? Or do I need to close both?

Thanks,

Tom

According to the documentation:

http://msdn.microsoft.com/en-us/library/system.io.streamreader_members.aspx

" Close - Closes the StreamReader object and the underlying stream, and
releases any system resources associated with the reader. (Overrides
TextReader.Close().) "

Hi,

Why not using a StreamReader from the start (if it's a Xml use
XmlReader instead)

if for some reason you still need to use your code do it like this:
using( FileStream fs = new FileStream(xmlFile, FileMode.Open,
System.IO.FileAccess.Read) ){
using( StreamReader sr = new StreamReader(fs) ){
}

}


It makes sure that the objects are disposed correctly

Much to my annoyance sr.Close will also close the stream.

So if I am going to read multiple files,

After the first file, I would do an sr.Close() (which closes fs as well).
So then I would do another:

fs = new FileStream(Anotherfile, FileMode.Open,
System.IO.FileAccess.Read);

And another:

sr = new StreamReader(fs);

but I never need to do an fs.Close() then.

Thanks,

Tom
