I have a simple model 

public class OneModel
   {
      public string Email { get; set; }

      public string Name { get; set; }
   }

And I created a simple list (OneModel datatype):

List<OneModel> someLists = new List<OneModel>{
            new OneModel{Name="A 1", Email="a1@some.com"},
            new OneModel{Name="A 2", Email="a2@some.com"},
            new OneModel{Name="A 3", Email="a3@some.com"},
            new OneModel{Name="B 1", Email="b1@some.com"},
            new OneModel{Name="C 1", Email="c1@some.com"},
  }

I want to create another list with random concatenated Name from first list, like as:
List<string> ... {"A 1-A 3", "A 2-C 1",...} or something like that.

How to do that ?

    Assuming .NET Framework 4.0:

    var random = new Random();
var result = new List<string>();
var count = random.Next(10, 20); // How many results do you want, really!?
for (int i = 0; i < count; ++i) {
    var query = from item in someLists
                order by random.Next()
                select item.Name;
    var items = query.Take(2);   // I assume you want two "names" in each item
    result.Add(string.Join("-", items));
}

    Examine result for your random-length list of random randomness…

    But what do you need it for…?
