Delegates vs Interfaces in C#

Question

I would like to pose this question as long as I am trying currently to dig into the use and the purpose of delegates, although it is likely to have been asked in similar formula

Answer 1

The biggest practical difference is that you can provide different delegate instances for the same delegate from the same class, while you cannot do it with interfaces.

delegate void XYZ(int p);

interface IXyz {
    void doit(int p);
}

class One {
    // All four methods below can be used to implement the XYZ delegate
    void XYZ1(int p) {...}
    void XYZ2(int p) {...}
    void XYZ3(int p) {...}
    void XYZ4(int p) {...}
}

class Two : IXyz {
    public void doit(int p) {
        // Only this method could be used to call an implementation through an interface
    }
}
