Double Array to Object Array?

Question

I have following array:

double[] Series = new double[] { 7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6 }

Series debugging view :

> Series
--> [0]
--> [1]
--> ...
--> [10]
--> [11]

When I write following:

object[] object_array = new object[] { Series }

object_array debugging view : (more than one level)

> object_array
--> [0]
----> [0]
----> [1]
----> ...
----> [10]
----> [11]

I write following to prevent new level:

object[] object_array = new object[Series.Length];
for (int i = 0; i < Series.Length; i++)
{
    object_array[i] = Series[i];
}

This is the one of the other solutions. But I think, there may be a better way to do this. Is there a problem for me to use above loop? Or different way?

(I use highcharts. If I give array that contains more than one level, it does not work.)

Thanks.

Seems like it will still pass a double array if you pass object_array[0]. — MrFox

var object_array = Series.Cast<object>().ToArray();

By doing this

object[] object_array = new object[] { Series }

you are assigning a double array as the first object item of the array object_array. You are actually creating 2D array with one row. You can use something like this:

double[] Series = new double[] { 7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6 };
object[] object_array = new object[Series.Length];
Series.CopyTo(object_array, 0);

@ErenErsönmez, I m sorry, I did syntax error. Your code is true, too.

Use LINQ:

double[] series = new double[] { 7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6 };
object[] seriesAsAbjectArray = series.Cast<object>().ToArray();

The reason why you cannot just cast it to an object[], is that double is a value type, and therefore you have to create a new array containing the boxed double-items.

You just assign it, because double is an object.

object[] object_array = Series;

I get an error when I try that: 'Cannot implicitly convert type 'double[]' to 'object[]''

This just hides the fact that it's a double array, instead of changing it to an object array.
