Why does: string st = "" + 12; work in c# without conversion? -

-

this super dumb, i've googled , checked references , cannot find answer... why can int or float etc added part of string without converstion not on it's own? is:

while work fine:

 string st = "" + 12;

this doesn't (of course):

 string st = 12;

where magic here? know works want know why works , how control how conversion done?

in first statement, left operand + string, , such + becomes concatenation operator. compiler finds overload operator takes string , arbitrary value operands. converts both operands strings (using tostring()) joins them.

the second statement not work because there's no implicit cast int string.

you can control how conversion done using parentheses change order of operations (semi-effective) or writing code handle conversions pre-emptively.
