error CS0104: ‘MinAttribute‘ is an ambiguous reference between 报错

error CS0104: ‘MinAttribute’ is an ambiguous reference between ‘UnityEngine.Rendering.PostProcessing.MinAttribute’ and ‘UnityEngine.MinAttribute’
‘MinAttribute’是’UnityEngine.Rendering.PostProcessing.MinAttribute’ 和’UnityEngine.MinAttribute’之间一个模糊引用，该错误需要把引用校正。
解决方法：
1.在每次使用中显式提供完整的命名空间前缀
将MinDrawer.cs中所有的MinAttribute替换为UnityEngine.PostProcessing.MinAttribute。
其他方法：

2.或者使用对别名使用指令名称空间/类型，例如
using UnityEngine = MinAttribute;
using PostProcessing = UnityEngine.Rendering.PostProcessing。
然后用名称空间别名标识类型，例如.
var dt = new PostProcessing.DataType();
3.您还可以在类级别上别名：
using UnityEngineMinAttribute = SUnityEngine.MinAttribute;
using PostProcessingMinAttribute = 'UnityEngine.Rendering.PostProcessing.MinAttribute;
…
var myObj = new PostProcessingMinAttribute();
