Strings are a very important data type in C#. The string data type is used for saving text as string. In programming terms, it's a sequence of characters. String is a reference type variable unlike other basic data type variables, such as int, float, and double, which are value type variables. Also, strings are immutable in nature, that is, the values present in them cannot change. In this section, we will look at different operations related to this data type.
So, look at the following code example:
string s = "Hello";
s = "world";
When we are assigning a Test value to the already declared string objects, internally, CLR allocates a new memory block for the modified string object. Hence, for every operation that we do on a string, instead of modifying of the same string object, a new string object is declared in CLR. Due to this, we...
