Get all children components

I want to get all my childrens components to change the button text to whatever I want, but what it does is it only changes the text of my first children.

Here is the line of code I'm having trouble with:

Code (CSharp):

1. GetComponentInChildren<Text>().text = "Hello World";

 

Code (csharp):

1. var allTexts = GetComponentsInChildren<Text>();
2. foreach (var thisText in allTexts) {
3. thisText.text = "Hello world";
4. }
