我用下面的code检索匿名类型命名的成员。有没有一些方法，我可以转换follwing code使用lambda EX pression实现这一目标，或者至少允许调用code使用LAMDA，即使内心深处我有使用一个字符串？

 私人牛逼GetAnonymousTypeMember＆LT; T＆GT;（对象anonymousType，串成员名），其中T：类
{
  变种anonTypesType = anonymousType.GetType（）;
  VAR propInfo = anonTypesType.GetProperty（成员名）;
  返回propInfo.GetValue（anonymousType，NULL）为T;
}
 

增加： 这就是 anonymousType 到达。该 GetAnonymousTypeMember 方法是私有的一类，其唯一的公共方法声明如下：

公共无效PublishNotification（NotificationTriggers触发，对象templateParameters）

我把这种方式：

  PublishNotification（NotificationTriggers.RequestCreated，新{NewJobCard =模型}）;
 

这是新{NewJobCard =模型} 是什么，是传递给 GetAnonymousTypeMember 为 anonymousType 。

 公共üGetMemberValue＆LT; T，U＆GT;（T例如，前pression＆LT; Func键＆LT; T，U＆GT; ＆GT;选择器）
{
    类型类型= ty​​peof运算（T）;
    VAR EXPR = selector.Body为MemberEx pression;
    字符串名称= expr.Member.Name;

    VAR道具= type.GetProperty（名称）;
    返程（U）prop.GetValue（例如，NULL）;
}
 

将使要做到：

 字符串名称= GetMemberValue（新{名称=你好}，O =＆GT; o.Name）;
 

I'm using the following code to retrieve named members from an anonymous type. Is there some way I could convert the follwing code to use a lambda expression to achieve this, or at least to allow the calling code to use a lamda, even if 'deep down' I have to use a string?

private T GetAnonymousTypeMember<T>(object anonymousType, string memberName) where T: class 
{
  var anonTypesType = anonymousType.GetType();
  var propInfo = anonTypesType.GetProperty(memberName);
  return propInfo.GetValue(anonymousType, null) as T;
}

ADDED: This is how anonymousType arrives. The GetAnonymousTypeMember method is private to a class whose only public method is declared as follows:

public void PublishNotification(NotificationTriggers trigger, object templateParameters)

I call this method:

PublishNotification(NotificationTriggers.RequestCreated, new {NewJobCard = model});

That new {NewJobCard = model} is what is passed to GetAnonymousTypeMember as anonymousType.

public U GetMemberValue<T, U>(T instance, Expression<Func<T, U>> selector)
{
    Type type = typeof(T);
    var expr = selector.Body as MemberExpression;
    string name = expr.Member.Name;

    var prop = type.GetProperty(name);
    return (U)prop.GetValue(instance, null);
}

Will enable to to do:

string name = GetMemberValue(new { Name = "Hello" }, o => o.Name);
