Question by graviton · Jan 04, 2016 at 08:55 PM · arrayobjectsystemdatetimetimespan

Help, getting ambiguous reference error

using "using System;" causes error

"Object is an ambiguous reference between Unity.Object and object"

for spriteArray

I need to use "using System;" for "TimeSpan" and "DateTime" calculations

e.g.

 using UnityEngine;
 using System.Collections;
 using UnityEngine.UI;
 using System;
 
 public class arrayAndDateTimeTest : MonoBehaviour 
 {
     
     public Object [] spriteArray;
     private DateTime myDateTime;
     private TimeSpan myTimeSpan;
 
     // Use this for initialization
     void Start () 
     {
         spriteArray = Resources.LoadAll ("EnergyBarSprites/Energy Bars"); //EnergyBarSprites
         myDateTime = System.DateTime.Now;
         myTimeSpan = TimeSpan.FromMinutes(10);
     }
 }

There are a couple of things you can do for this situation.

Fully qualify the class name. You can do that on Object..

 UnityEngine.Object[] spriteArray...

or the System classes (while removing using System - it's not needed if you fully qualify the types)...

 private System.TimeSpan myTimeSpan...


Another option is to use the using keyword to declare an alias.

 using UnityObject = UnityEngine.Object;

 UnityObject[] spriteArray...

or do it on the System classes (again, remove using System)...

 using TimeSpan = System.TimeSpan;
 using DateTime = System.DateTime;

Or various combinations of those sorts of things.
