TryParse

We want result to be set to the value of someObject.SomeProperty, and in any other case to default to 99.

int result =  0;
int max = int.TryParse(someObject.SomeProperty, out result) ? result : 99;

equivalent to

int result =  0;
int max = 99;

if(int.TryParse(someObject.SomeProperty, out result) == true) 
{
    max =  result; 
}
else // ok, maybe this 'else' is redundant
{ 
    max = 99;
}
