C# 从分组Linq查询生成字符串

给定以下代码：

var people = new List<person>(){ new person { Name = "John", FamilyName = "Pendray" },
             new person { FamilyName = "Emery", Name = "Jake"},
             new person { FamilyName = "Pendray", Name = "Richard" } };

var q = from p in people
                 orderby p.Name
                 group p by p.FamilyName into fam
                 orderby fam.Key
                 select new { fam.Key, members = from p in fam select p };

var people=new List（）{new person{Name=“John”，FamilyName=“Pendray”}，
新人{FamilyName=“Emery”，Name=“Jake”}，
新人{FamilyName=“Pendray”，Name=“Richard”}；
var q=人的p值
orderby p.Name
p组由p.FamilyName改为fam

在fam select p}中选择new{fam.Key，members=from p；

是否可以将最后一行替换为将输出包含以下两个字符串的IEnumerable

的select：
“彭德雷·约翰·理查德”
“金刚砂杰克”？可以这样将linq查询投影到字符串中吗

编辑：我知道这可以通过进一步的代码实现，但我感兴趣的是，这是否可以从linq查询本身中实现，就像VB能够从查询中投影xml一样（特别是本页上的最后一个代码块）
一样

您必须更改“选择零件”。最简单的方法是定义一个函数，该函数接受IEnumerable并生成该字符串，然后调用该函数

people = new List<person>(){ new person { Name = "John", FamilyName = "Pendray" },
         new person { FamilyName = "Emery", Name = "Jake"},
         new person { FamilyName = "Pendray", Name = "Richard" } };

var q = from p in people
        orderby p.Name
        group p by p.FamilyName into fam
        orderby fam.Key
        select new { Key = fam.Key, Text = GetText(fam) };



// and elsewhere...
private string GetText(IEnumerable<person> family) {
    string result = "Whatever"; // build the result string here
    return result;
}

Pendray John Richard

        select GetText(fam);

var q = from p in people
        orderby p.Name
        group p by p.FamilyName into fam
        orderby fam.Key
        select fam.Key + " " + string.Join(" ", (from fm in fam select fm.Name).ToArray());
