Answer 1

private int? currentRegionId呵呵 是不是红色的地方错了

Answer 2

                [CompilerGenerated] 
        private string <NullToDisplay>k__BackingField;    
        [CompilerGenerated] 
        private string <Separator>k__BackingField; 
        [CompilerGenerated] 
        private string <Titles>k__BackingField; string <Titles>，，怎么又是泛型，又是特定类型。。改下。。

Answer 3

晕，int?是可空类型，怎么错了！
问题是  private string <NullToDisplay>k__BackingField;  改为
private list<NullToDisplay>k__BackingField;

Answer 4

string 什么时候成泛型类了……

Answer 5

对啊，string  就是一个简单的类啊。不能用泛型类表示的。如3楼 改为list就可以了
