Because of the formats, you can also put them in a List<string> and call .Sort().

Help needed with string operation

Hi I need a bit of help.

I have this string: "10 > 8 > 99> 34"

From this string, how can I extract all the numbers?

Basically, when I receive the above string, I want to get every number out of it and do something with that number.

Thanks

string[] numberstrings = mystring.split('>');
int[] numbers = new int[numberstrings.Length];
for (int i=0; i<numberstrings.Length; i++)
{
    numbers[i] = int.Parse(numberstrings[i]);
}

You might want to make sure that all the strings that come out of the split really are numbers through so you should probably wrap the line in the for loop with a try/catch statement to be safe.

Problem with GZipStream [modified]

Hello!

I am trying to use GZipStream to compress an XML file before writing it to disk. But unfortunately it doesn't work 100% correctly... The file written to disk is a valid GZ file up to the very last few bytes. The whole file can be decompressed without any problems, except that the very last few bytes are broken and get decompressed incorrectly...

My code basically looks like this:

FileStream fs = new FileStream(strFilePath, FileMode.Create, FileAccess.Write, FileShare.None);
Stream writerStream = new GZipStream(fs, CompressionMode.Compress);

XmlTextWriter xtw = new XmlTextWriter(writerStream, Encoding.UTF8);
WriteDocument(xtw); // Creates the XML document

xtw.Flush();
writerStream.Flush();
fs.Flush(); fs.Close();

Files mostly get decompressed incorrectly like this (_ are spaces):

________</Group>
____</Group>
</Root>
</SplConfFile5ile5ile5ile5ile5ile5ile5ile5ile5ile5ile5ile5ile5ile5ile5il

Do you have any idea what could be the problem? Why are the very last few bytes corrupted?

Best regards
Dominik

I've found the problem now. There is a bug in the GZipStream class of .NET 2.0 (yes, in the class, not in my code). You need to close the GZipStream manually...

For more details see this bug report at MSDN Product Feedback Center:
http://lab.msdn.microsoft.com/productfeedback/viewfeedback.aspx?feedbackid=efaebf8f-8b1c-45e1-b355-6c6953aa221a[^]

I wonder why they released .NET 2.0 with such a long-known, serious bug...

Best regards

hi when we press alt+shift inside textboxes, we convert to the second
keyboard language . what i want is to do this programmatically
i.e directly start writing in the second language

You might be able to accomplish this by calling the SendKeys.Send method, passing a string which represents Alt + Shift. The docs for that method explain the symbols used to represent those non-alphanumeric keys.

Can you explain this better please, do you want to identify the file type from byte patterns or simple compare files? What do you mean by diginity?
