Methods and codeblock marked unsafe. A string is often implemented as an array data structure of bytes (or words) that stores a sequence of elements, typically characters, using some character encoding More general, string may also denote a sequence (or list) of data other than just characters. However, if array types were treated as invariant, it would only be possible to call these functions on an array of exactly the type object[] One could not, for example, shuffle an array of strings Therefore, both java and c# treat array types covariantly
For instance, in java string[] is a subtype of object[], and in c# string[] is a subtype of object[] This comparison of programming languages (array) compares the features of array data structures or matrix processing for various computer programming languages. Rope (data structure) a simple rope built on the string of hello_my_name_is_simon In computer programming, a rope, or cord, is a data structure composed of smaller strings that is used to efficiently store and manipulate longer strings or entire texts. The ecma standard lists these design goals for c# The language, and implementations thereof, should provide support for software engineering principles such as strong type checking, array bounds checking, [21]
