c# - Two different generic types as result and parameter -

with method can return unknown data type :

private t call<t>(uri uri) t:new()  { }

but how pass unknown data type (not same) parameter :

private t call<t>(uri uri, ??? parameters) t:new()  { }

add generic type parameter:

private t call<t, tother>(uri uri, tother parameters) t:new()  { }
