自定义公式列表数据验证

Question

因此，在excel中，您可以使用由公式确定的列表来创建数据验证规则。有谁知道如何使用C＃和ClosedXML做到这一点？

Answer 1

您可以使用ICollection或IList实现自己的集合，并实现添加和删除操作的规则。

public class myList : IList
{
    private List<string> _list;
    public myList()
    {
        _list = new List<string>();
    }

    public object this[int index] { get => _list[index]; set => throw new NotImplementedException(); }

    public bool IsFixedSize => throw new NotImplementedException();

    public bool IsReadOnly => throw new NotImplementedException();

    public int Count => throw new NotImplementedException();

    public bool IsSynchronized => throw new NotImplementedException();

    public object SyncRoot => throw new NotImplementedException();

    public int Add(object value)
    {
        throw new NotImplementedException();
    }

    public void Clear()
    {
        throw new NotImplementedException();
    }

    public bool Contains(object value)
    {
        throw new NotImplementedException();
    }

    public void CopyTo(Array array, int index)
    {
        throw new NotImplementedException();
    }

    public IEnumerator GetEnumerator()
    {
        throw new NotImplementedException();
    }

    public int IndexOf(object value)
    {
        throw new NotImplementedException();
    }

    public void Insert(int index, object value)
    {
        throw new NotImplementedException();
    }

    public void Remove(object value)
    {
        throw new NotImplementedException();
    }

    public void RemoveAt(int index)
    {
        throw new NotImplementedException();
    }
}

对于某些不需要任何更改的操作，请在_list中使用相同的操作来实现它们，例如索引设置器。
