The var keyword in C# 3.0 has been the subject of much scorn recently, which I feel is uncalled for. It is really a matter of personal preference - I use the var keyword in LINQ queries, and I think there's no other good way of storing the output of a LINQ query. Implicit typing is just an equally strong typing convention as explicit typing as the compiler determines the actual type, never so wrongly.Anonymous types are, to me, a blessing of LINQ, and there's no better way to save variables of anonymous types than in a var. Using the var keyword in any context other than LINQ, however, would be undesirable, as readability can be compromised and the code would unnecessarily be cluttered.
The concept of "var" is really interesting at first thought but only useful commercially in my perspective in LINQ.
ReplyDeleteThough people who use C# and can't seem to remember the datatypes of variables can put this feature to an extra-ordinary use :)
