Question

class A
{
   public string[] X {get;set;}
   public string[] Y {get;set;}
}

class B
{
  public string X {get;set;}
  public string Y {get;set;}
}

transfer data of A’s object to B’s array with Linq? suppose Object of A have 10-10 size X and Y and I want to transfer into B array (B[] b = new B[10])

A a = new A();
//put 10 items in both x and y
B[] b = new B[10];
//here I want to get a's data to b

Answer 1

You can use Zip method from LINQ:

A a = new A();
B[] bs = a.X.Zip(a.Y, (x, y) => new B() { X = x, Y = y })
            .ToArray();

Or use Select with index:

B[] bs = a.X.Select((x, i) => new B {X = x, Y = a.Y[i]})
            .ToArray();

Another way using Enumerable.Range if you get stuck on .NET 3.5:

B[] bs = Enumerable.Range(0, 10)
                   .Select(i => new B {X = a.X[i], Y = a.Y[i]})
                   .ToArray();
