Kuidas erineb String klass teistest andmetüüpidest C#-s?

In C#, the String class differs from most other data types in that it is a reference type, but it behaves like an immutable (immutable) object.

Main differences:

• Immutability: Once a string is created, its content cannot be changed. Any operation that appears to modify the string (e.g., concatenation) actually creates a new String object.

• Reference type: String is a class, not a struct, so variables of type string hold a reference to the object in memory.

• Optimizations: Thanks to immutability, strings can be used in the string pool (interning), which saves memory.

• Garbage collection: Since strings are objects, they are managed by the garbage collector, simplifying memory management.

Example:

string a = "hello";
string b = a;
a = a + " world"; // A new string object is created

// b remains "hello", a becomes "hello world"

Thus, despite being a reference type, strings behave like values in terms of immutability, which ensures safety and predictability when working with text.
