Guys,

any suggestion for this error!
"Found a low surrogate char without a preceding
high surrogate at index: 738"
so far I know this much "it sounds like there was an invalid combination of bytes
in the string. A UTF-16 string uses two bytes (16 bits)
to encode characters. Some of the byte combinations are
reserved (apparently) and can't be used in a UTF-16 string."

any idea except try and catch to just skip it?

What is the value that is causing the error, at index 738?

"\0\0\0\0\0\0\0\0\0\0\0\0\0\bi\0\0\0\0\0\0\b\0\0 M
\t\0
\0\0\0\0\0\0\0\0\0\0\0\0\0\0

\0\0\0\0\0\0\0\0 \0\0\0\0\0\0\0\b#1428;\0\0M
R\0\5555 test WAY"

looks like that but kind of longer...

What is that coming from? Do all of the lines of data look like this?

Yes, but it works for some of them. I mean it writes the data into the error file but when it gets to this line for example, it throws the above exception. by the way I am using Streamwriter for writing this data too. I read somewhere it cuases the problem too.
any idea?

In one of the constructors for the StreamWriter class, there is an object of type System.Text.Encoding. Try a different encoding type, and see if that works.

worked as a charm. thanks
