Labels and GOTOs are considered bad practice and as far as I know there is no reason to use it in C#.

What is the use of labels in C#?

Answer 1

Code generators sometimes use labels and gotos. It can simplify the code generation logic in some cases. Goto statements are generally shunned for readability reasons, but if the code is not intended to be read then that is a moot point.

I have also seen cases where a decompiler gets confused enough by the IL and outputs goto statements instead of the well crafted sequence of instructions that a human would have conjured. If goto statements were not legal then the decompiler might have to completely punt on that section of code. This way, at least, it can generate something that can be round-tripped.
