String interpolation on an existing String

I receive a string out of a Database. Say like "Hello {Name}" which is safed in the variable x I know want to use string interpolation on that string I know this works

string Name = "Peter"
string hello = $"Hello {Name}";

string Name = "Peter"
string hello = $"Hello {Name}";

Result would be hello Peter What I want to do is this

string Name = "Peter"
string hello = $"x";

string Name = "Peter"
string hello = $"x";

With the same result Is this even possible?

REPL Result: Success

string s = "{0} was first, {1} was second";
string.Format(s, "hello", "world")

string s = "{0} was first, {1} was second";
string.Format(s, "hello", "world")

Result: string

hello was first, world was second

hello was first, world was second

forgot you need explicit numbers for format but you can't grab the values of random variables
