Object array dynamic

Question

I have the following line in my code:

object[] inputs = new object[] {"input1", "input2", "input3", "input4"};

I would like to know how (without knowing how many elements will be in the array) add dynamically using a loop like this:

object[] inputs;
foreach (string key in Request.Form.Keys)
{
     inputs[0] = key;
}

How could I do this?

Thanks in advance.

Best Regards.

Answer 1

Could you just not use:

List<object> list = new List<object>();
list.Add(key);

Answer 2

我想你想要像IEnumerable.ToArray这样的功能。

object[] inputs = Request.Form.Keys.ToArray()

Answer 3

use List<T> it has same access efficiency as array ( O(1) ) and have method Add to add elements. Read more here: http://msdn.microsoft.com/en-us/library/6sh2ey19.aspx
