C#10

 

Assignment and declaration in the same deconstruction

In the previous versions of C#, developers can either assign values to existing variables or declare new variables in deconstruction. The combination of assigning a value to an existing variable and declaring a new variable was restricted. This restriction is now removed, and you can assign a value and declare a new variable in a single deconstruction.

Before C# 10

(string name, string email) = var employee;

Or
string name;
string email;
(name, email) = employee;

In C# 10

string name;
(name, string email) = employee;
