c# - Can an interface have a templated method name? -

i know answer no, still confirm.
can interface have variable method name?

interface ivariablemethodname //something similar <t> {    void t(int param);    void t(string param); } 

i have classes require function overload couple functions same parameter different name , have different functionality. there better way instead of making bunch interfaces same content except method name?

edited: example

class adder {     public int add(int a, int b){}     public float add(float a, float b){}     public decimal add(decimal a, decimal b){} }   class subber {     public int sub(int a, int b){}     public float sub(float a, float b){}     public decimal sub(decimal a, decimal b){} } 

what trying similar examples difference return type class itself. , methods have different functionality.

i still not sure understand question completely. however, sure not possible define single interface interface members can take on different names depending on implementing class.

given underlying goal 1 of maintainance — is, ensure compile-time error if class fails implement of necessary methods — seems me closest 1 can come declare interface general-purpose method names, , have each specific type implement interface through delegation type-specific methods.

for example:

interface ioperator {     int operation(int a, int b);     float operation(float a, float b);     decimal operation(decimal a, decimal b); }  class adder : ioperator {     public int add(int a, int b){}     public float add(float a, float b){}     public decimal add(decimal a, decimal b){}      public int operation(int a, int b) { return add(a, b); }     public float operation(float a, float b) { return add(a, b); }     public decimal operation(decimal a, decimal b) { return add(a, b); } }   class subber : ioperator {     public int sub(int a, int b){}     public float sub(float a, float b){}     public decimal sub(decimal a, decimal b){}      public int operation(int a, int b) { return sub(a, b); }     public float operation(float a, float b) { return sub(a, b); }     public decimal operation(decimal a, decimal b) { return sub(a, b); } } 

unfortunately, not guarantee each type has implemented type-specific methods in question. require each type implements interface, , if have developers on team implement new method in interface means other adding corresponding type-specific method class , calling it, have bigger problems @ hand. :)

it seems unfortunate me interface might not used in way interfaces are: i.e. support polymorphic implementation of specific contract. maybe you'd find once have in place, makes sense go ahead , generalize other code.

for matter, if point, maybe you'll find makes more sense stop writing these types different method names in each type, given across different types methods same. :)
