VB.NET

With Alpha.Beta.Gama.Eta.Zeta
    a = .ZetaPropertyA
    b = .ZetaPropertyB
    c = .ZetaPropertyC
End With

C#?

a = Alpha.Beta.Gama.Eta.Zeta.ZetaPropertyA
b = Alpha.Beta.Gama.Eta.Zeta.ZetaPropertyB  
c = Alpha.Beta.Gama.Eta.Zeta.ZetaPropertyC

Nope, doesn't exist.

Though you could shorten it a bit:

var z = Alpha.Beta.Gama.Eta.Zeta;

z.ZetaPropertyA = a;
z.ZetaPropertyB = b; 
z.ZetaPropertyC = c;

for your other case:

var z = Alpha.Beta.Gama.Eta.Zeta;

a = z.ZetaPropertyA;
b = z.ZetaPropertyB;
c = z.ZetaPropertyC;

That should've been obvious though ;)

For new instances you can use object initializer:

Alpa.Beta.Gama.Eta = new Zeta
{
    ZetaPropertyA = a, 
    ZetaPropertyB = b,
    ZetaPropertyC = c
}

No, there's nothing like the with construct in C#.

Sorry, C# doesn't have that. The object initializer @Jakub suggests might provide an alternative, or:

If you design Zeta yourself, you could use the fluent interface design pattern. That would allow you to do:

Alpha.Beta.Gama.Eta.Zeta
    .SetPropertyA(A)
    .SetPropertyB(B)
    .SetPropertyC(C);

Which comes close to what you want, at the expense of a lot of work elsewhere. And remember that a fluent interface is not always the best design choice.

Nope. The workaround is a (short) local variable name instead of with. Adds a few characters per line, but you still end up with fully qualified references.
