FileStream & StreamReader?

[Arpan]

A file can be read using only the StreamReader object like this:

Dim sReader As StreamReader
sReader = New StreamReader(Server.MapPath("File1.txt"))
While(sReader.Peek > -1)
Response.Write(sReader.ReadLine)
End While

as well as using the FileStream object along with the StreamReader
object like this:

Dim fStream As FileStream
Dim sReader As StreamReader

fStream = New FileStream(Server.MapPath("File1.txt"), FileMode.Open,
FileAccess.Read)
sReader = New StreamReader(fStream)
While(sReader.Peek > -1)
Response.Write(sReader.ReadLine)
End While

Now how do I decide which way to go when I want to read a file?

If I am not mistaken, the second way would involve additional overheads
as compared to the first way, isn't it?

Thanks,

Arpan

I would only use the second way if I needed to open the stream in a
specific (non read-only) manner. Also, please remember to Dispose these
objects when you're done with them!

they are the same. if you pass a path to Streamreader, it creates a
FileStream and wraps its.

Does that mean there aren't any additional overheads involved when
using both the FileStream object & the StreamReader object as compared
to using just the StreamReader object to read files?
