C#:匿名类型和属性名称 [英] C#: Anonymous types and property names

问题描述

这之间有什么区别吗?

dataContext.People.Select(ø => new
{
     Name = ø.Name,
});

和这个:

dataContext.People.Select(ø => new
{
     ø.Name,
});

?

推荐答案

它们是相同的；如果未指定名称(并且右侧是简单的成员访问权限)，则假定现有成员的名称.该名称仅在以下情况下必需:

They are identical; if no name is specified (and the right-hand-side is a simple member-access) then the name of the existing member is assumed. The name is only necessary to:

• 将名称更改为 else (例如Name = grp.Key)
• 为非成员访问表达式命名(例如Count = grp.Count())

• change the name to something else (for example Name = grp.Key)
• to give a name to a non-member-access expression (for example Count = grp.Count())
