Question

I have the following class:

class Item
{
    public string[] field1;
    public int field2;
}

Well i have collection of items. How can i convert these collection to

class Item
{
    public string field1;
    public int field2;
}

I mean something like Items.SelectMany(x => x.field1) but i need to save filed2 value for each element of my collection.

example

field1:{"asd","asdf","fscsd"}
field2:123

->

field1:{"asd"}
field2:123

field1:{"asdf"}
field2:123

field1:{"fscsd"}
field2:123

Answer 1

Try this:

var res = Items.SelectMany(x => x.field1.Select(s => new {field1=s, x.field2}));

You will get back an enumerable of anonymous objects, each with two fields – field1 and field2.
