Strange StreamReader.Read() error

Strange StreamReader.Read() error

Strange StreamReader.Read() error

(OP)
Colleagues,
Here's the part of the code (screenshot, erred during debug run, in IDE):



I cannot comprehend why it errs on the 2nd iteration coz the size of the file it reads is 89 Mb, and I'm reading it by 1 Mb chunks.
Could you, please take a look and tell me who's the crazy one, me or .NET?

TIA!

Regards,

Ilya

RE: Strange StreamReader.Read() error

I'm afraid it is you. You have misunderstood the StreamReader.Read method - the index is the index into the character buffer (i.e. lsBlock) not the position you are reading from in the StreamReader (that particular pointer is maintained internally by the StreamReader as you read ...). So the quick fix is to change

CODE -->

lnPos = loStreamReader.Read(lsBlock, lnPos + 1, lnChunk) 

to

CODE -->

lnPos = loStreamReader.Read(lsBlock, 0, lnChunk)
