Hello,
Win 7 - 64-bit Windows Form App
Did a clean and rebuild on the sln but the program crashes on the StreamReader line. The file is definitely there and in the correct place. Anything wrong with this call?
public static class BOBroker
{
public static string GetClassDefsXml()
{
StreamReader classDefStream = new StreamReader(
typeof(BOBroker).Assembly.GetManifestResourceStream("WCM.BO.ClassDefs.xml"));
string _classDefsXML = classDefStream.ReadToEnd();
classDefStream.Close();
return _classDefsXML;
}
Thanks, DKH

what is the error?

Furthermore, I don't understand why people tend to code several lines to read all of a text file, when there is a single-line solution in
string allTheFilesText=File.ReadAllText(path);

With respect, Luc, you once admonished a poster that he was supposed use a loop to read all of a file because "that's what streams are for."

I'm all in favor of streaming data, especially when the amount of data can be large and there really is no need to have it all in memory at once; streaming then means having an explicit loop of input-process-output, dealing with a fraction of the data at a time.
When the amount of data is known to be really small, or there is a need to have it all at once, then one can rightfully decide not to stream, and to read or write all in one go; but then I insist on taking the easiest way to do that, which is by using a single File method.
Using a stream class to not stream the data just does not make any sense. StreamReader.ReadToEnd() gets abused over and over, almost as much as String.ToString().

It's a resource, not a file, in this case.
|
|
|
|
|
My mistake, sorry.
|
|
|
|
|
Have you added the file to the project as an embedded resource?
Best regards

Is there a question mixed in there somewhere?
Why is common sense not common?

what is that soposto mean??
That C# code is for those who want to create split file app jst copy n paste n modify put in buttons etc.
At one point i needed one so i put this out for those who where in my position!!!!!

Then write an article instead of posting code in forums where questions are asked...

It's "supposed". TXTSPEAK is heavily frowed upon here as it makes you look childish.

OK, great. The problem you didn't consider is that the forums fill up so fast nobody will see your code by the end of next week because it'll be buried by a dozen pages of forum posts.
Yeah and don't think "Oh it'll still be visible because of Google." Think again. If everyone used Google people would be finding their own answers instead of relying on the regulars here to spoon-feed them answers.

It's just a shame that you ignored the tips and tricks, and articles sections where this would have ben much better received.

If you look at the very first item in this forum, it says "How to ask a question". This forum is for asking questions. So when you post something like that, we are left wondering what the questions is. In any case, you could have been more clear by stating that you're not asking a question(which the purpose of the forum) but posting a solution to a problem you encountered. Nonetheless, thanks for sharing.

Right now due to increasing our recruitment possibilities of new staff we are moving over to C#
What is the best way that I can go about making a data collection object available to all forms in C#
In Visual Basic we can use a module and put in a friend based variable i.e. friend GlobalData as string. (the string variable is the easiest way I could explain this as an example!) This then makes the variable available to any form / class in the assembly.
Is there a way of doing this in C# or do I have to look at passing the information back and forth between each form?
Many Thanks
Simon
