Nullable vs Int32

 Nullable<Int32> vs Int32




Nullable<Int32> and Int32? are two ways of expressing the same concept in C#.

Nullable<Int32> is the long-form way of declaring a nullable integer, where you explicitly use the Nullable<T> struct with the type parameter Int32.

Int32? is the shorthand or syntactic sugar provided by C# for declaring nullable types. It's essentially the same as Nullable<Int32>, but in a more concise form.

So, whether you write Nullable<Int32> or Int32?, you're declaring a nullable integer type. It's just a matter of preference and readability. Most developers prefer the shorthand form (Int32?) for its brevity and clarity.
