Can I define a type that is an alias of another type (like typedef in
C++)?
Not exactly. You can create an alias within a single file with the
"using" directive: using System; using Integer = System.Int32; // alias
But you can't create a true alias, one that extends beyond the file in
which it is declared. Refer to the C# spec for more info on the 'using'
statement's scope.
Is it possible to have different access
modifiers on the get/set methods of a property?
No. The access modifier on a property applies to both its get and set
accessors. What you need to do if you want them to be different is make
the property read-only (by only providing a get accessor) and create a
private/internal set method that is separate from the property.
Is it possible to have a static indexer in C#?
No. Static indexers are not allowed in C#.
Does C# support #define for defining global constants?
No. If you want to get something that works like the following C code:
#define A 1
use the following C# code: class MyConstants
{
public const int A = 1;
}
Then you use MyConstants.A where you would otherwise use the A macro.
Using MyConstants.A has the same generated code as using the literal 1.
Does C# support templates?
No. However, there are plans for C# to support a type of template known
as a generic. These generic types have similar syntax but are
instantiated at run time as opposed to compile time. You can read more
about them here.
Does C# support parameterized properties?
No. C# does, however, support the concept of an indexer from language
spec. An indexer is a member that enables an object to be indexed in the
same way as an array. Whereas properties enable field-like access,
indexers enable array-like access. As an example, consider the Stack
class presented earlier. The designer of this class may want to expose
array-like access so that it is possible to inspect or alter the items
on the stack without performing unnecessary Push and Pop operations.
That is, Stack is implemented as a linked list, but it also provides the
convenience of array access.
Indexer declarations are similar to property declarations, with the main
differences being that indexers are nameless (the name used in the
declaration is this, since this is being indexed) and that indexers
include indexing parameters. The indexing parameters are provided
between square brackets.
Does C# support C type macros?
No. C# does not have macros. Keep in mind that what some of the
predefined C macros (for example, __LINE__ and __FILE__) give you can
also be found in .NET classes like System.Diagnostics (for example,
StackTrace and StackFrame), but they'll only work on debug builds.
Can you store multiple data types in System.Array?
No.
Is it possible to inline assembly or IL in C# code?
No.
Can you declare the override method static while the original method
is non-static?
No, you cannot, the signature of the virtual method must remain the
same, only the keyword virtual is changed to keyword override
Does C# support multiple inheritance?
No, use interfaces instead.
Can multiple catch blocks be executed?
No, once the proper catch code fires off, the control is transferred to
the finally block (if there are any), and then whatever follows the
finally block.
Can you override private virtual methods?
No, moreover, you cannot access private methods in inherited classes,
have to be protected in the base class to allow any sort of access.
What is a pre-requisite for connection pooling?
Multiple processes must agree that they will share the same connection,
where every parameter is the same,
What is the data provider name to connect to Access database?
Microsoft.Access.
Why does my Windows application pop up a console window every time I
run it?
Make sure that the target type set in the project properties setting is
set to Windows Application, and not Console Application. If you're using
the command line, compile with /target:winexe & not target:exe.
