Hi all,

Based on my functionality I want convert int[] to object[]. I tried to do this but I can't to convert this.

example:

C#

int[] intrs = new int[] { 400, 435, 446, 900 };

            object[] obj = intrs;

Can you any one tell me how to convert int[] to object[]?

Be explicit:

int[] intrs = new [] { 400, 435, 446, 900 };

object[] obj = intrs.Select(x => x as object).ToArray();

Exactly the same as the code posted in solution 3 eight years ago.

There is a very nice explanation for the issue here that you should read - Can't convert value type array to params object[][^]

Solution 3

C#

int[] intrs = new int[] { 400, 435, 446, 900 };

            object[] obj = (from i in intrs select i).Cast<object>().ToArray();

it will help you use this casting method

Solution 1

You can't convert an array that simply - you can't explicitly cast it either. What you have to do is create a new object[] from the existing data.
It's pretty easy though:

C#

int[] intrs = new int[] { 400, 435, 446, 900 };
object[] obj = Array.ConvertAll(intrs, x => (object)x);
