After reading What's the rationale for null terminated strings? and some similar questions I have found that in C#/.Net strings are, internally, both length-prefixed and null terminated like in BSTR Data Type.
What is the reason strings are both length-prefixed and null terminated instead of eg. only length-prefixed?

C is a general-purpose programming language and can efficiently work on enterprise applications, games, graphics, and applications requiring calculations, etc. C language has a rich library which provides a number of built-in functions. It also offers dynamic memory allocation.
Because C comes after B The reason why the language was named “C” by its creator was that it came after B language. Back then, Bell Labs already had a programming language called “B” at their disposal.
The C programming language is so popular because it is known as the mother of all programming languages. This language is widely flexible to use memory management. C is the best option for system level programming language.
C++ was originally called 'C with classes,' and was built as an extension of the C language. Its name reflects its origins; C++ literally means 'increment C by 1. ' It was renamed C++ in 1983, but retains a strong link to C, and will compile most C programs.
Length prefixed so that computing length is O(1).
Null terminated to make marshaling to unmanaged blazing fast (unmanaged likely expects null-terminated strings).

Here is an excerpt from Jon Skeet's Blog Post about strings:
Although strings aren't null-terminated as far as the API is concerned, the character array is null-terminated, as this means it can be passed directly to unmanaged functions without any copying being involved, assuming the inter-op specifies that the string should be marshalled as Unicode.
