I am currently parsing boolean into string using this line, but it ain't working all of times, is there any alternative ?
bool.Parse(listItem.Properties["Boolean Property"].ToString()) == false

bool? temp = listItem.Properties["Boolean Property"] as bool;
bool result = temp ?? true;
This code will read the property as a boolean, though return null if the property is null or not a bool (hence it is put into the nullable bool 'temp'). We then make it a normal bool use the ?? operator - if temp is null, result will be set to 'true'. Otherwise, result is set to whatever value temp has.
Using the '.Tostring()' risks a NullReferenceException if the property isn't set...

I was checking if property exists in code above using "ContainsField" but it was throwing exception for converting string into boolean but thanks anyway I give it a try, cheersMuhammad Raja– Muhammad Raja2012-10-09 11:34:11 +00:00Commented Oct 9, 2012 at 11:34

No problem, that's the pattern I use now, 'cos it avoids the .ToString (I did get caught but NullRef exceptions), and the same pattern works nicely with other types, such as ints.Andy Burns– Andy Burns2012-10-09 11:35:44 +00:00Commented Oct 9, 2012 at 11:35
string valueS = "true";
Convert.ToBoolean(valueS);
