For example, consider creating an array of integers. Since int is a value type, this allocates 1,000 integers in one contiguous block of memory. Write (a[123]); 32 | Chapter 2: C# Language Basics // 0 Value types versus reference types Whether an array element type is a value type or a reference type has important performance implications. When the element type is a value type, each element value is allocated as part of the array. For example: public struct Point { public int X, Y; } ... X; // 0 Had Point been a class, creating the array would have merely allocated 1,000 null references: public class Point { public int X, Y; } ...

By default, this happens silently—no exception is thrown. Although the C# specification is agnostic as to the result of an overflow, the CLR always causes wraparound behavior. MaxValue); // True Integral arithmetic overflow check operators The checked operator tells the runtime to generate an OverflowException rather than failing silently when an integral expression or statement exceeds the arithmetic limits of that type. The checked operator affects expressions with the ++, −−, +, − (binary and unary), *, /, and explicit conversion operators between integral types.
