c# - Is it possible to detect the variable of a using from another function and access that variable? -

i have function calls function. want know if within second function can detect if being invoked first function within using-scope. if can detect it, want access variable inside using-scope. cannot send variable through parameter.

for example:

// normal call otherfunction void function1() {     someclass.otherfunction(); }   // calling using somevar void function2() {     using(var somevar = new somevar())     {         someclass.otherfunction();     } }  // calling using other variable, in case, similar behaviour function1() void function3() {     using(var anothervar = new anothervar())     {         someclass.otherfunction();     } }  class someclass {     static void otherfunction()     {          // how know if being called inside using(somevar)          // , access local variables somevar     } } 

you use same mechanisme system.transaction.transasctionscope. works if context's can have same base class. base class registerers himself in static property during construction , removes himself @ dispose. if context active, surpressed until newest context disposed again.

using system;  namespace contextdemo {     class program     {         static void main(string[] args)         {             detectcontext();             using (new contexta())                 detectcontext();             using (new contextb())                 detectcontext();         }          static void detectcontext()         {             context context = context.current;             if (context == null)                 console.writeline("no context");             else                  console.writeline("context of type: " + context.gettype());         }     }      public class context: idisposable     {         #region static members          [threadstatic]         static private context _current;          static public context current         {                         {                 return _current;             }         }          #endregion          private readonly context _previous;          public context()         {             _previous = _current;             _current = this;         }          public void dispose()         {             _current = _previous;         }     }      public class contexta: context     {     }      public class contextb : context     {     } }
