As per my understanding, there is no null-termination at the end of a C# string. So how does Length get to know how many characters a string have?
Thanks, Gyan

Introduction. The string length in C is equal to the count of all the characters in it (except the null character "\0"). For Example, the string "gfddf" has a length of 5 and the string "4343" has a length of 4.
strlen() function in c The strlen() function calculates the length of a given string. The strlen() function is defined in string. h header file. It doesn't count null character '\0'.
strlen function in C/C++ and implement own strlen() The strlen function computes the length of the given string. It takes a string as an argument and returns its length. It doesn't count the null character ( '\0' ).
It's stored in a field within the object.
As it happens, strings are null-terminated internally in the current implementation of .NET, but that's only for the sake of interop, so that code which does expect null-terminated strings can be given the same chunk of memory to work with.
Note that having it in a field is a good idea in terms of performance anyway - it makes finding the length an O(1) operation instead of O(N).
