c# - Accesing variable declared without a name (just new keyword) -

i have dataset named ds in want load xml.

so use function ds.readxml();

the paramter readxml function xmltextreader object.

if pass object

ds.readxml(new xmltextreader(application.startuppath + "\\mydatasource.xml")); 

the dataset loaded. later on, want close xmltextreader object. although didn't declared name like

xmltextreader reader = new xmltextreader(somepath); 

how can close reader???

you'll need use variable, otherwise can't access it.

and while @ it, use using statement:

string path = path.combine(application.startuppath, "mydatasource.xml")); using (var reader = new xmltexttreader(path)) {   ds.readxml(reader); } 

the using statement automatically calls dispose on reader when exiting scope of using statement.

note: should use path.combine instead of concatting path yourself. saves lot of trouble.
