关于c＃：使用Lambda表达式查询字典

Querying a Dictionary with a Lambda Expression

我在下面创建了一些示例代码，并尝试使用lambda表达式来查询SoftwareComponents字典。问题是，当我需要进一步细化查询时，查询返回一个igrouping类型的var，以便返回一种igrouping类型，其中第一个字符串是softwarecomponent.componentname，第二个字符串是softwarecomponent.componentdescription。有人知道怎么做吗？

我希望返回的数据看起来像："新类型说明""组件1""组件2""旧类型说明""组件3""组件4"
