c# - Call generic Method with multiple generic Types without specifying every single generic Type -

so have generic method multiple generic types.

now i'd call method way (using types of , b , specifying return type):

class example {      t1 genericmethod<t1, t2, t3>(t2 parameter1, t3 parameter2)      {         t1 returnvalue = default(t1);          // ... returntype, parameter1 , parameter2          return returnvalue;     }      void accessgenericmethod()     {         var = new foo1();         var b = new foo2();         var result = genericmethod<returntype>(a, b); // doesn't work     } } 

and avoid call genericmethod way

var result genericmethod<returntype, foo1, foo2>(a, b); 

in c#, there no partial type inference: must either specify or none of generic arguments, latter works if compiler able infer types context. return types cannot infered (except special cases such lambdas), want not possible.

two workarounds:

a: move t1 method class

class example<t1> {     t1 genericmethod<t2, t3>(t2 parameter1, t3 parameter2) 

b: replace t2 , t3 object

class example {     t1 genericmethod<t1>(object parameter1, object parameter2)
