Parsing boolean ListItem property into string

Question

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

Answer 1

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...

Answer 2

string valueS = "true";

Convert.ToBoolean(valueS);
