c# - How to assign out parameter in function? -


i have method returns object , has out parameter. method calls method takes in same out paramter out paramter. gives build error on return statement:

the out parameter 'param1' must assigned before control leaves current method

the code looks like:

public typea method1(typea param1, out bool param2) {   /... logic here .../   submethod(out param2);   /... logic here .../   return param1; }

param2 manipulated in submethod(), not in method1(). there else need do?

in case, assign 'default' value. regardless of bool, int, myfoo, etc. - set default value.

public typea method1(typeb param1, out bool param2) {   param2 = false;   // default value;   // or   param2 = default(bool); // in cases not sure default    /... logic here .../   submethod(out param2);   /... logic here .../   return param1; // update: <- receiving exception }

but need identify why exception refers 'param1' when param1 not @ fault in example ( for clarification : assuming typeb : typea , constrained).

i believe passing param2 out parameter in submethod(...) removes obligation assign param2. however, have not assigned param1. there more going on here has not been explained?
