請教下EF問題,高手進來幫看下

報錯:The foreign key component 'rd_Id' is not a declared property on type 'SJResourceReqMAS'. Verify that it has not been explicitly excluded from the model and that it is a valid primitive property.
外国关键组件的rd id”不是一个声明的属性类型的SJResourceReqMAS’。确认它没有被明确地排除在模型,它是一个有效的原始属性。
當我把[ForeignKey("SJResourceReqMAS")]註釋掉就映射成功了，但是也改變了SJResourceReqMAS結構如圖：
