It might be helpful,

C#

{
    Int32 one = 1, two = 2;
    object[] myArray = { one, two };
}

VS is deriving the type of the array from the type of the variable used in its creation (in this case userID), there are 2 ways around this, either:

C#

object[] parameters = new[] { (object)UserID };

or

C#

object[] parameters = new object[] { UserID };

Personally, i prefer the 2nd option.

Here's some ideas for you:

XML

private Int32 UserID;
private Int32 AdminID;
private List<Int32> ListOInt32s;
private List<object> ListOObjects;

private void MakeIDS(Int32 uID, Int32 aID)
{
    UserID = uID;
    AdminID = aID;

    // anonymous type
    // exists only in the scope of this method call
    var IDS = new {UserID, AdminID};

    // generic strongly typed
    ListOInt32s = new List<Int32> {UserID, AdminID};

    // generic typed as Object
    ListOObjects = new List<object> {UserID, AdminID};
}

private void button1_Click(object sender, EventArgs e)
{
    MakeIDS(4,5);
}
