How to convert an object to a byte array in C#
...
@Smith: You can cast the enum to int (or if you have specified any other type as storage for the enum) and write it. When you read it you can cast it to the enum type.

How to convert a Collection to List?
... Just to note that there are different side effects to the two approaches: casting the collection to a list and then sorting will also sort the original collection; creating a copy will not.

+1: Even though the currently selected answer is absolutely correct, this one by JaredPar is the better one. It simply is the best solution for most practical cases.

When is assembly faster than C?
...2 bits: MSVC doesn't always do a good job when multiplying 32-bit integers cast to 64, so intrinsics helped a lot.
C doesn't have a full-multiplication operator (2N-bit result from N-bit inputs). The usual way to express it in C is to cast the inputs to the wider type and hope the compiler rec...

...2d") will return with the type CanvasRenderingContext2D. You don't need to cast it explicitly.

Objective-C: difference between id and void *
...afe, you would pass the is-case-sensitive indicator in the context, likely casting on the way in and way out.
Fragile and error prone, but the only way.
Blocks solve this -- Blocks are closures for C. They are available in Clang -- http://llvm.org/ and are pervasive in Snow Leopard (http://develo...
How does Java handle integer underflows and overflows and how would you check for it?
...e source type:
public int addWithOverflowCheck(int a, int b) {
// the cast of a is required, to make the + work with long precision,
// if we just added (a + b) the addition would use int precision and
// the result would be cast to long afterwards!
long result = ((long) a) + b;

Seeking clarification on apparent contradictions regarding weakly typed languages
...C# allows all three of those forms of "strong" typing to be violated. The cast operator violates static typing; it says to the compiler "I know more about the runtime type of this expression than you do". If the developer is wrong, then the runtime will throw an exception in order to protect type s...
