How can a variable of one type in C# be assigned to another if they are not in the same inheritance branch?

Question

C++ / C#

Please, prompt:
Here is in C# here such type XNamespace.
Inherits directly from System.Object.
At the same time, this form of writing is quite legitimate:

XNamespace ds = "http://www.w3.org/2000/09/xmldsig#";

How is this possible? After all, the string type is neither parent nor child of XNamespace, but one is cast to the other.

Answer 1

Because there is such an operator that constructs an XNamespace from a string.

Answer 2

this means that there is either an overloaded assignment operator , but most likely just a type extension , for the necessary conversion
