转换IEnumerable<；对象>；到匿名类型

我想转换IEnumerable，定义如下：

public class NameVal 
{
    public string Name { get; set; }
    public string Content { get; set; }
}
IEnumerable<NameVal> contents =  new List<NameVal>()
{
    new NameVal { Name = "title", Content = "My new post" },
    new NameVal { Name = "body", Content = "This is my first post!" }
};

到匿名类型data:

var data = new
{
    title = "My new post",
    body = "This is my first post!"
};

有人知道怎么做吗？谢谢

var x = new ExpandoObject() as IDictionary<string, object>;
foreach (NameVal nameVal in contents) {
    x.Add(nameVal.Name, nameVal.Content);
}
dynamic d = x;
Console.WriteLine(d.title);
Console.WriteLine(d.body);

var data = contents.Select(x => new
{
    title = x.Name,
    body = x.Content
});
