Difference between shadowing and overriding in C#?
...Foo()); // output 1
Console.WriteLine(clB.Bar()); // output 1
//now let's cast B to an A class
Console.WriteLine(((A)clB).Foo()); // output 5 <<<-- shadow
Console.WriteLine(((A)clB).Bar()); // output 1
Suppose you have a base class and you use the base class in all your code instead of t...
What is the exact problem with multiple inheritance?
...g part of the problem, if one does not need to allow identity-preserving upcasts and downcasts among all of the types from which an instance is derived or for which it is substitutable. Given X:B; Y:B; and Z:X,Y; assume someZ is an instance of Z. With virtual inheritance, (B)(X)someZ and (B)(Y)som...
Literal suffix for byte in .NET?
...
f = float
m = decimal
d = double
If you want to use var, you can always cast the byte as in var y = (byte) 5
Although not really related, in C#7, a new binary prefix was introduced 0b, which states the number is in binary format. Still there is no suffix to make it a byte though, example:
var b...
Get the generated SQL statement from a SqlCommand object?

// Alternatively, use the format string "yyyy'-'MM'-'dd'T'HH':'mm':'ss'.'fffK"

Why don't Java Generics support primitive types?
...entirely compile-time construct - the compiler turns all generic uses into casts to the right type. This is to maintain backwards compatibility with previous JVM runtimes.
This:
List<ClassA> list = new ArrayList<ClassA>();
list.add(new ClassA());
ClassA a = list.get(0);
gets turned i...

Freely convert between List and IEnumerable
...interface is immutable so it will not cause problems in that direction and casting back just feels dirty when you have a function that will take care of type safety.

java: Class.isInstance vs Class.isAssignableFrom
...n instance. It returns true when the parameter obj is non-null and can be cast to MyClass without raising a ClassCastException. In other words, obj is an instance of MyClass or its subclasses.
MyClass.class.isAssignableFrom(Other.class) will return true if MyClass is the same as, or a superclass ...
Implicit type conversion rules in C++ operators
I want to be better about knowing when I should cast. What are the implicit type conversion rules in C++ when adding, multiplying, etc. For example,
