How to use streamreader to read ascii 8 charecters

Friends,

Want to read a textfile with characters that go above 7F ( ascii > 128) and
put the results line by line in a string to process it further
I used a streamreader to do so but the readline() methods in someway skipps
the characters > 127 .
I used the binary reader as well, same result.

string regel;
StreamReader sr = new StreamReader ( ImportFile, System.Yext.Uni code.UTF8);
While ( regel = sr.readline()) !=null)
{
I do something here
}

How to solve this?

Regards

Gerrit Esmeijer

There's no such thing as ASCII > 128.

Perhaps you mean Encoding.Defaul t?

Yes you caught me. Fine OK Sorry
but now to the point.

I tried several things. What I would like is reading a string that consists
of characters them a degree sign en a diameter sing ( zero with a cross line
(alt-155 on your keyboard - I would not dare to say ascii-155) :-) ); put
them in a string variable and store the result in a
field in a database. Leter I need to make lists with on them the same
characers againg.
And how about all those names with Umlauts (German) like , , etc.
There must be a way to simply read those chracters and store them in a
string variable.

Converting to ascii converts althose character > 127 into a ?
( f etc)
For me, coming from vb6 this was no problem.
Now in C# I have till now not found a way to read these characters . In
spite of all the explenation tou are referring to.

PLEASE show me a piece of code that puts these Character into a string.
Regards, gerrit Esmeijer

Absolutely - but where are you trying to read them from? What's teh
file format, if you're reading it from a file?

Yes, it would, as those characters aren't in ASCII.
For me, coming from vb6 this was no problem.

Have you tried Encoding.Defaul t as I suggested?

Jon,
First I did not know want you ment by >> Default <<. Since you are referring
to it for the second time I got into the theory a bit more and see, the
Nickle fell and it worked.
Things that are obvious for some people do not need to be that for other
(among them is me) <<

Thanks
Gerrit

I'm having a problem with the streamreader class. When i read out of a file, characters like are taken out when i do readline. Why does this happen? When i switch the encoding to ascii, it replaces those characters with a question mark. How do i get them to read correctly from a file? So the character is correctly read into the .net program?

Hi, I am trying to read a file, make changes, and write it to a new file. The original file has the copyright character which is ascii 169 I believe, which is more than 7 bits. I am using typical StreamReader object to read in the file, but it is not getting it correctly. If I make the encoding type Ascii, it turns it into a question mark. If I use UTF7 or UTF8, it ignores it. Unicode was jibberish. Any ideas? Here is the file I...

I am reading from a file and trying to find out if it has characters above ASCII 127 in it. My sample file does have several of these characters. However, the streamreader seems to skip over them. Even if I read in lines and then write them out to another file, the high ASCII number characters disappear. My code:
