Possible to put 'stream' character data into a string without creating a temporary fixed-sized buffer?

[Jack]

Hi,

I do a webrequest and it returns some text data in a stream. I want to
put this text data into a string. I've got it working just fine, but I
have to

put the text data into into a fixed-size buffer BEFORE I put it into a
string (ConstBufferByt eSize=1000000). This fixed size buffer wastes
space. Is

it possible to somehow assign it straight to a string, or somehow do
this 'dynamically' ?
'' Put the XML response into a string to display
Dim tempBuffer(Cons tBufferByteSize ) As Byte
Dim enc As New System.Text.ASC IIEncoding

' responseStream. Length.ToString () ' <- Can't seem to get
the length to signify the buffer size here ???

responseStream. Read(tempBuffer , 0,
ConstBufferByte Size) ' Read from the stream x bytes and put into a
temporary buffer

responseStream. Close() ' Close
the request stream to free up resources

strResponse =
enc.GetString(t empBuffer) ' Put the response into
a string (finally!)

Any kind of help will do,

thankyou

Jack.

The buffer is used by the web request to buffer the incoming request.
Strings are immutable, so a new copy of the string is created each time it
is changed. Thus .NET probably buffers to memory first, then builds a
string afterwards for efficiency sake.

OK. So I need to put the stream into a fixed sized buffer first? Isn't
there another way?

Just set your buffer size to something smaller, like 8K. The Read
method should return how many bytes were actually read. You would
have to read in a loop until Read returns 0 indicating the end of the
stream.

I haven't tried this, but what about:

' Define ConstBufferByte Size to somthing like 1024

Dim tempBuffer(Cons tBufferByteSize ) as Byte
Dim str As StringBuilder = New StringBuilder

Do While True
Dim len As Integer

len = responseStream. Read(tempBuffer , 0, ConstBufferByte Size)
If len = 0
Exit Do
End If
str.Append(enc. GetString(tempB uffer, 0, len))
End Do

strResponse = str.ToString()
