Downcasting an entire array

Question

In Unity I am trying to detect all the components of type text on an object

this.GetComponents(typeof(Text))

but it returns an array of components. Since I know every component must be of type text I should be able to downcast it. I tried to explicit cast it

Text[] a = (Text[])this.GetComponents(typeof(Text));

but that didn't work. Text is a derived class of component, but I don't know how to downcast the array so I can use the methods that are associated with type text. Can someone show me how I can convert the array to one of the type Text?

Answer 1

You should use the generic syntax: this.GetComponents<Text>(). That returns a Text[] so no need to cast anymore.

Answer 2

From the docs, you can use the generic method GetComponents without needing to type cast each.

using UnityEngine;

public class Example : MonoBehaviour
{
    void Start()
    {
        HingeJoint[] hinges = GetComponents<HingeJoint>();
        for (int i = 0; i < hinges.Length; i++)
        {
            hinges[i].useSpring = false;
        }
    }
}
