public class Test : MonoBehaviour
{[HideInInspector][Header("数量")][SerializeField]public int num;[Header("分布类型")][SerializeField]public DistributionType distType;[HideInInspector][Header("位置")][SerializeField]public List<Vector3> positions;
}public enum DistributionType
{None,test1,test2,test3,
}

[CustomEditor(typeof(Test))]
public class TestEditor : Editor {public SerializedObject obj;public SerializedProperty distType;public SerializedProperty positions;public SerializedProperty num;void OnEnable(){obj = new SerializedObject(target);distType = obj.FindProperty("distType");num = obj.FindProperty("num");positions = obj.FindProperty("positions");}public override void OnInspectorGUI(){//base.OnInspectorGUI();obj.Update();if (distType.enumValueIndex == 0){EditorGUILayout.PropertyField(positions, true);}else{EditorGUILayout.PropertyField(num);}obj.ApplyModifiedProperties();}
}

在数据类中（文中是Test类）数组类的字段在开启基类的base.OnInspectorGUI();不能用[HideInInspector]，否则会无法显示数组内容。
