アイテムの種類がすべて異なる場合は、より直感的に取得できるようにクラスを作成しました。
このクラスの使用法：
var t = TypedTuple.Create("hello", 1, new MyClass());
var s = t.Get<string>();
var i = t.Get<int>();
var c = t.Get<MyClass>();
ソースコード：
public static class TypedTuple
{
public static TypedTuple<T1> Create<T1>(T1 t1)
{
return new TypedTuple<T1>(t1);
}
public static TypedTuple<T1, T2> Create<T1, T2>(T1 t1, T2 t2)
{
return new TypedTuple<T1, T2>(t1, t2);
}
public static TypedTuple<T1, T2, T3> Create<T1, T2, T3>(T1 t1, T2 t2, T3 t3)
{

Tuple非常に一般的です、それであなたが得るすべてです
