0.场景如下：

1.获取场景中所有的Go，包括嵌套的，隐藏的。需要注意的是要进行go.scene.name != null，这句判断，否则会包含很多来自其他地方的go(不只是来自Project视图)

using UnityEngine;
using UnityEditor;

/// <summary>
/// 查找GameObject在场景中所有被引用的地方
/// </summary>
public class FindGoInScene {

    [MenuItem("GameObject/FindGoInScene", priority = 0)]
    static void Init()
    {
        GameObject[] goes = Resources.FindObjectsOfTypeAll<GameObject>();
        for (int i = 0; i < goes.Length; i++)
        {
            GameObject go = goes[i];
            if (go.scene.name != null)
            {
                Debug.Log(go.name);
            }
        }
    }
}

输出如下：

2.查找引用

TestFindGoInScene.cs

using UnityEngine;

public class TestFindGoInScene : MonoBehaviour {

    public GameObject temp;
}

FindGoInScene.cs

using UnityEngine;
using UnityEditor;
using System.Reflection;

/// <summary>
/// 查找GameObject在场景中所有被引用的地方
/// </summary>
public class FindGoInScene {

    [MenuItem("GameObject/FindGoInScene", priority = 0)]
    static void Init()
    {
        GameObject[] goes = Resources.FindObjectsOfTypeAll<GameObject>();
        for (int i = 0; i < goes.Length; i++)
        {
            GameObject go = goes[i];
            if (go.scene.name != null)
            {
                if (go != Selection.activeGameObject)
                {
                    //Debug.Log(go.name);
                    Find(go);
                }
            }
        }
    }

    static void Find(GameObject go)
    {
        Component[] components = go.GetComponents<Component>();
        for (int i = 0; i < components.Length; i++)
        {
            Component component = components[i];
            FieldInfo[] fields = component.GetType().GetFields(BindingFlags.Public | BindingFlags.Instance);
            for (int j = 0; j < fields.Length; j++)
            {
                var value = fields[j].GetValue(component);
                if (value == (object)Selection.activeGameObject)
                {
                    Debug.LogWarning(go.name);
                }
            }
        }
    }
}

输出如下：
