To implement functions with the same signature from multiple interfaces in a class, you can use explicit interface implementation. By prefixing the interface name before the method, you can disambiguate between the two methods.

using System;
interface IInterface1
{
 void Todo();
}
interface IInterface2
{
 void Todo();
}
class MyClass : IInterface1, IInterface2
{
 void IInterface1.Todo()
 {
 Console.WriteLine("Implementation of Todo from IInterface1");
 }
 void IInterface2.Todo()
 {
 Console.WriteLine("Implementation of Todo from IInterface2");
 }
}
class Program
{
 static void Main()
 {
 MyClass obj = new MyClass();
 ((IInterface1)obj).Todo();
 ((IInterface2)obj).Todo();
 }
}

MyClass implements both IInterface1 and IInterface2 with separate implementations of the Todo method for each interface. By casting the object to the respective interfaces, you can call the specific implementations.
