I keep getting Error CS0029

I am getting the following error:

CS0029 Cannot implicitly convert type UnityEngine.Renderer[] to System.Collections.Generic.List<UnityEngine.Renderer>

The code is: 

using UnityEngine;
using System;
using System.Collections;
using System.Collections.Generic;

public class AssignShadersToChildren : MonoBehaviour
{
    private new GameObject renderer;

    public Shader shader; // This should hold the Shader you want to use

    void Start()
    {
        // We create a list that will hold all the renderers(objects) 
        // so we can then assign the shader
        List<Renderer> renderers = new List<Renderer>();
        renderers = GetComponentsInChildren<Renderer>();

        // For every Renderer in the list assign the materials shader to the shader
        foreach (Renderer r in renderers)
        {
            r.material.shader = shader;
        }
    }
}

Why not just enumerate the items?

void Start()
{
    foreach (Renderer r in GetComponentsInChildren<Renderer>())
        r.material.shader = shader;
}

the only thing that's matter is that GetComponentsInChildren<Renderer>() should return IEnumerable<Renderer> whatever it is (array, list...)

You can simply omit the type and let the compiler do the work! There is no need to create a new list if you are then assigning the result of a method call to the `renderers' variable.

void Start()
{
    var renderers = GetComponentsInChildren<Renderer>();
    foreach (Renderer r in renderers)
    {
        r.material.shader = shader;
    }
}

The error is descriptive. You need to convert the results to a List:

renderers = GetComponentsInChildren<Renderer>().ToList();

Or change the local variable to be an array:

Renderer[] renderers = GetComponentsInChildren<Renderer>();
