initialize and assign value to multiple variables vb.net

Question

there is the option to do this in vb.net

Dim a, b, c As Single, x, y As Double, i As Integer

also you can do

Dim myString = String.empty

Is there a way to initialize and assign multiple variables like the first example but using the assignment as the second one?

Do you really think such a coding style would be clearer than a separate statement per variable? — Jon Skeet

I am applying that style to a function already tested and well commented so I think in that case is good to do so — edgarmtze

Absolutely not - just because a function is already tested and commented doesn't mean you should feel free to make the implementation unreadable. Declaring lots of variables - of different types, no less! - in the same statement and assigning them values - sounds like a way of making it take much longer to read and understand. — Jon Skeet

I tested it in VS 2008, but I don't think that the Syntax of the Dim statement changed since. You will have to specify the type for each variable, if you initialize them

Dim a As Single = 1, b As Single = 2, x As Double = 5.5, y As Double = 7.5

Or you can let VB infer the type and use type characters (here ! for Single):

Dim a = 1!, b = 2!, c = 3!, x = 5.5, y = 7.5, i = 100

By hovering with the cursor over the variables in VS you will see that the types are inferred correctly as Single, Double and Integer. You could also use F for single. See: Constant and Literal Data Types (Visual Basic)
