通过 LINQ 语句 C# 从 Group 返回多个值

Question

Hi I am having trouble getting the correct values from my group by statement. I am trying to get a value grouped by another value here:

var allGuilds = Player.dictGuilds;


var guildTypeRoster =
    from g in allGuilds
    where g.Value.GuildType.ToString() == CBGuildType.SelectedItem.ToString()
    orderby g.Value.GuildName
    group g.Value.GuildServer.ToString() by g.Value.GuildName;

So basically I'm trying to group the names in guild by the server they are on. I run into problems when trying to output both the server I am grouping by and the name here:

foreach (var pair in guildTypeRoster)
{
    OutputBox.AppendText(pair.Key + "\n");
}

I can only get the key of the value which is the names I grouped by. I'm trying to also display the server and have both display but I cannot seem to find a way to do that. If anyone could help that would be great.

You will want to iterate over each group's records so you need an additional loop.

foreach (var pair in guildTypeRoster)
{
    foreach(var value in pair) 
    {
        OutputBox.AppendText(pair.Key + ": " + value.GuildName + "\n");
    }
}
