将字符串列表转换为ICollection的MailAddresses

Question

ICollection<MailAddress> toCollection = to.Split(',');

此操作失败，因为字符串不会自动MailAddress ...

如何迭代字符串，将每个实例设为MailAddress，然后将其添加到新的ICollection？

Answer 1

你可以做到

using System.Linq;
....
IEnumerable<MailAddress> addresses = to.Split(',').Select(i => new MailAddress(i));

编辑：将其设为ICollection<MailAddress>

ICollection<MailAddress> collection = to.Split(',').Select(i => new MailAddress(i)).[ToList | ToArray]();
