Code with undefined behavior in C#

Question

In C++ there are a lot of ways that you can write code that compiles, but yields undefined behavior (Wikipedia). Is there something similar in C#? Can we write code in C# th

Answer 1

Many and subprograms have requirements that can be summarized as:

1. When given valid data, produce valid output.

2. Refrain from launching nuclear missiles or negating the laws of time and causality, even when given invalid input.

One of the major design goals of Java and .NET languages is that unless code makes use of certain which are marked as "unsafe", no particular effort is generally required to meet the second constraint above [though some behaviors related to garbage collection and Finalize can be a little weird from the time/causality standpoint, those can be described as exceptions to normal rules of causality, rather than a total revocation of them]. That situation is very different from the situation in C, where many kinds of data-dependent errors (e.g. integer overflow) may result in compilers behaving in arbitrary fashion including making whatever assumptions would be necessary to avoid overflow. The truly horrible kinds of Undefined Behavior which are encouraged in hypermodern C philosophy do not exist in C# or other .NET languages outside of "unsafe" blocks.
