Question

As in the tile: overriding ToString() on the a KeyValuePair<> struct (System.Collections.Generic).I’m wondering if this can be done at all in C# (sealed structs).

Could anyone provide some insight or alternative approaches?

Or should I simply forget overriding and go for the following:

class MyKeyValuePair
{
    public KeyValuePair<T> Pair { get; set; }
    public MyKeyValuePair(KeyValuePair<T> pair)
    {
        this.Pair = pair;
    }
    public override ToString()
    {
        ...
    }
}

No.

You cannot modify existing types, and structs cannot be inherited.
