D vs. C#

== Related =
* Languages vs. D
*

What D and C# have in common:

Have a syntax heavily influenced by C/C++.
Use garbage collection.
The "." operator is always used (instead of -> or :: operators)
Include null as a keyword.
Values are initialized before they're used.
Feature error handling using try-catch-finally.
Pointers are allowed (not that their use is encouraged).
goto is a valid command (if you need it it's there).
A 'foreach' operator, though they are slightly different. (See the differences section)
Inner classes

How D is different:

There is no VM in D. Everything is compiled to machine code.
In D, one can use integers to govern if statements.
D's modules are similar to packages, but symbols can be imported into the global scope.
You can use inline assembly in D.
D doesn't have an as operator. However, casting works like as: The c# code Cat cat = dog as Cat would be written as Cat cat = cast(Cat) dog; in D. (cat would be null if dog can't be cast to a Cat).
Instead of foreach (Foo foo in bars) (C#) you would write foreach (Foo foo; bars) - And if you wanted a variable set to the index number of the element being acted on, you can do foreach (int i, Foo foo; bars) in D.
