group:Convert a string to bool
c#:
not? If so... Give the method a return typ of bool and return it based on the result. public bool GetTheData() { if(the table has records...) { return true; } else { return false; } } public void CallingMethod() { if(GetTheData) { do something... } else { do something else... } } Hope this helps. bobc [quoted text, click to view] "ReidarT" <reidar@eivon.no> wrote in message news:O4u$TaqFFHA.3648@TK2MSFTNGP10.phx.gbl... >I have a value from a field (int) in a table like > string strPlayerLoginStatus = dsPlayer2.Tables[0].Rows[0][1].ToString(); > > I like to convert the strPlayerLoginStatus from string to int to use it in > an if statement > > How do I convert the variable? > > regards > > reidarT > >

I have a value from a field (int) in a table like
string strPlayerLoginStatus = dsPlayer2.Tables[0].Rows[0][1].ToString(); I like to convert the strPlayerLoginStatus from string to int to use it in an if statement How do I convert the variable? regards reidarT

You shouldn't use this ng to learn the basics of C#, but to help you solve problems after the learning stage. If you have a good library in the neighbourhood photocopy the first 100 pages of C# Design Patterns by James W. Cooper ISBN 0-201-84453-2 Don't read the rest of the book. Don't buy the book. It gives you a super brief and well written introduction into the basics of C#. Else buy / read Learning C# O'Reilly ISBN 0-596-00376-5
try
{ int value = int.Parse( strPlayerLoginStatus ); } catch (System.FormatException ex) { // handle exception } "ReidarT" <reidar@eivon.no> schreef in bericht news:O4u$TaqFFHA.3648@TK2MSFTNGP10.phx.gbl...

Also, one person's trivial task is another person's challenge.

Re Cooper: [quoted text, click to view] > If he or she doesn't know design patterns, the OP > may benefit from reading this book in its entirety > I've heard a lot of weird things before Yes, I get the impression that you have! (1) There are better books around on the subject of design patterns (2) The subject matter and the examples used are totally unsuited for an *absolute* starter. Re using the ng by an *absolute* starter: First reading an introductory text will get the OP up to speed faster. To that end I suggested two excellent texts, one very concise but sufficient for starters, the other more comprehensive.
