不，你不能命名元组成员。

中间的方法是使用ExpandoObject而不是Tuple。

c# 7元组的例子

var tuple = TupleExample(key, value);

     private (string key1, long value1) ValidateAPIKeyOwnerId(string key, string value)
            {
                return (key, value);
            }
      if (!string.IsNullOrEmpty(tuple.key1) && tuple.value1 > 0)
          {
                    //your code

                }     

如果你的项目类型都不同，这里是一个类，我做了更直观地获得他们。

这个类的用法:

var t = TypedTuple.Create("hello", 1, new MyClass());
var s = t.Get<string>();
var i = t.Get<int>();
var c = t.Get<MyClass>();

源代码:

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)
    {
        return new TypedTuple<T1, T2, T3>(t1, t2, t3);
    }

    public static TypedTuple<T1, T2, T3, T4> Create<T1, T2, T3, T4>(T1 t1, T2 t2, T3 t3, T4 t4)
    {
        return new TypedTuple<T1, T2, T3, T4>(t1, t2, t3, t4);
    }

    public static TypedTuple<T1, T2, T3, T4, T5> Create<T1, T2, T3, T4, T5>(T1 t1, T2 t2, T3 t3, T4 t4, T5 t5)
    {
        return new TypedTuple<T1, T2, T3, T4, T5>(t1, t2, t3, t4, t5);
    }

    public static TypedTuple<T1, T2, T3, T4, T5, T6> Create<T1, T2, T3, T4, T5, T6>(T1 t1, T2 t2, T3 t3, T4 t4, T5 t5, T6 t6)
    {
        return new TypedTuple<T1, T2, T3, T4, T5, T6>(t1, t2, t3, t4, t5, t6);
    }

    public static TypedTuple<T1, T2, T3, T4, T5, T6, T7> Create<T1, T2, T3, T4, T5, T6, T7>(T1 t1, T2 t2, T3 t3, T4 t4, T5 t5, T6 t6, T7 t7)
    {
        return new TypedTuple<T1, T2, T3, T4, T5, T6, T7>(t1, t2, t3, t4, t5, t6, t7);
    }

    public static TypedTuple<T1, T2, T3, T4, T5, T6, T7, T8> Create<T1, T2, T3, T4, T5, T6, T7, T8>(T1 t1, T2 t2, T3 t3, T4 t4, T5 t5, T6 t6, T7 t7, T8 t8)
    {
        return new TypedTuple<T1, T2, T3, T4, T5, T6, T7, T8>(t1, t2, t3, t4, t5, t6, t7, t8);
    }

}

public class TypedTuple<T>

    public TypedTuple(T item1)

    public TSource Get<TSource>()
    {
        object value;
        if (this.items.TryGetValue(typeof(TSource), out value))

    {
        Item8 = item8;
    }

    private T8 item8;
    public T8 Item8 { get { return this.item8; } set { this.item8 = value; this.items[typeof(T8)] = value; } }
}

为什么不使用多个返回而不是使用元组

var handler = GenerateFromMethod1(hits);
Process(handler.string1, handler.string1);

private static (string string1, string string2) GenerateFromMethod1()
{

}

我会把商品名称写在汇总单上。 因此，通过将鼠标悬停在helloworld()函数上，文本将显示hello = Item1和world = Item2

 helloworld("Hi1,Hi2");

/// <summary>
/// Return hello = Item1 and world Item2
/// </summary>
/// <param name="input">string to split</param>
/// <returns></returns>
private static Tuple<bool, bool> helloworld(string input)
{
    bool hello = false;
    bool world = false;
    foreach (var hw in input.Split(','))
    {
        switch (hw)
        {
            case "Hi1":
                hello= true;
                break;
            case "Hi2":
                world= true;
                break;
        }

    }
    return new Tuple<bool, bool>(hello, world);
}

我想我会创建一个类，但另一种选择是输出参数。

public void GetOrderRelatedIds(out int OrderGroupId, out int OrderTypeId, out int OrderSubTypeId, out int OrderRequirementId)

因为你的元组只包含整数，你可以用Dictionary<string,int>来表示它

var orderIds = new Dictionary<string, int> {
    {"OrderGroupId", 1},
    {"OrderTypeId", 2},
    {"OrderSubTypeId", 3},
    {"OrderRequirementId", 4}.
};

但我也不建议这样做。
