Shorthand notation for class member initialization

Question

In a C# block, I can define and initialize a variable as follows:

var xyz = new Xyz();

The type of xyz will be set accordingly.

However, at the class level, I have to specify the type twice:

class Abc
{
    Xyz xyz = new Xyz();
}

Is there a shorthand syntax that avoids typing out the type name twice?

This isn't such a big deal with short types like Xyz but a shorter notation would help with LongTypeNames.

Answer 1

If you are using a few particular types and want them shortened you can create an alias with a using statement, eg:

using ShortName = Abc.Xyz.ClassWithAVeryLongNameThatYouDontLikeTypingTooOften;

then within that file you could do something like:

class Abc
{
    ShortName xyz = new ShortName();
}

But as far as I know there's no var equivalent at the class level.
