大致原理

AlwaysIncludedShaders在unity的Project Setting->Graphics中有展示。但是无论是去查看RenderSettings、GraphicsSettings、EditorGraphicsSettings下都没有这个的一个字段或者方法！

所以最终的解决就是使用放射的方式去访问！

具体

GraphicsSettings.GetGraphicsSettings()返回的是一个UnityEngine.Object的对象，但时这个对象里就有我们需要的AlwaysIncludedShaders

通过查看unity反射的代码，可以看到以下的内容:

var graphicsSettings = GraphicsSettings.GetGraphicsSettings();
var serializedObject = new SerializedObject(graphicsSettings);
SerializedProperty serializedProperty = serializedObject.FindProperty("m_AlwaysIncludedShaders");

这样就能获取到m_AlwaysIncludedShaders的数组了！

然后我们能通过SerializedProperty对m_AlwaysIncludedShaders进行读写了！

完整代码！

var graphicsSettings = GraphicsSettings.GetGraphicsSettings();
var serializedObject = new SerializedObject(graphicsSettings);
SerializedProperty serializedProperty = serializedObjeFindProperty("m_AlwaysIncludedShaders");
if (serializedProperty.isArray)
{
    for (int x = 0; x < serializedProperty.arraySize; x++)
    {
        SerializedProperty property = serializedProperGetArrayElementAtIndex(x);
        var sh = property.objectReferenceValue;
        Debug.LogError(sh);
    }
}
