LINQ - Map 字符串 arrays 到对象列表

Question

How do I map string arrays to a list of objects? A for loop would do it but wondering if there's a more elegant way to do this? Perhaps with Linq?

String arrays:

string[] names = { "john","jane"};                                 
string[] companies = { "company ABC", "" };
string[] affiliations = { "affiliation 1", "affiliation 2" };

Contact:

public class Contact
{
    public string Name { get; set; }
    public string Company { get; set; }
    public string Affiliation { get; set; }
    public string Address { get; set; }
    public string City { get; set; }
    public string State { get; set; }
}

Answer 1

Assuming you've ensured all of the arrays ( all of them , not just the first three in your question) are exactly the same size and in the right order (so all the values will correspond to the right Contact objects), a for loop will suffice...

var contactList = new List<Contact>();

for (int i = 0; i < names.Length; i++)
{
    contactList.Add(new Contact
    {
        Name = names[i], 
        Company = companies[i], 
        Affiliation = affiliations[i],
        // etc
    });
}

Answer 2

If you truly have both those definitions in your code, then you should just skip the string array step entirely. Instead, initialize a list of Contact directly:

var contacts = new List<Contact>()
{
    new Contact()
    {
        Name = "john",
        Company = "company ABC",
        Affiliation = "affiliation 1",
    },
    new Contact()
    {
        // ...
    },
    // ...
};

This is more readable, and is less error prone, in case you have mis-matched list sizes, or don't have some data for one of the entries.
