I am using C# and I have a List like this List<double[]>, I want convert into integer and store all elements in another list like this List<int[]>.
How can I do this?

There is a heap of ways to do this, for example you can use linq like this:
List<int> integers = new List<int>();
List<double> doubles = new List<double>();
for (int i = 0; i < 10; i++)
doubles.Add(i + new Random().NextDouble());
foreach (var d in doubles)
{
Console.WriteLine(d);
}
Console.WriteLine("------------------------");
integers = doubles.Select(d => (int) d).ToList(); // EVERYTHING IS DONE HERE
foreach (var i in integers)
{
Console.WriteLine(i);
}
Or you can simply loop through the list or use an iterator and cast them explicitly.

Thank you @Mok. But, how can I convert string to
List<double[]> or List<int[]>?

suppose you have a
List of String called strings, you can do this: doubles = strings.Select(s => Double.Parse(s)).ToList();
