如何遍历ExpandoObject并获取特定值

dynamic expando = new ExpandoObject();
expando.Name = "John";
expando.Age = 25;
expando.City = "New York";

foreach (var property in expando.GetType().GetProperties())
{
    var propertyName = property.Name;
    var propertyValue = property.GetValue(expando);
    Console.WriteLine($"{propertyName}: {propertyValue}");
}

var specificProperty = "Age";
var specificValue = expando.GetType().GetProperty(specificProperty)?.GetValue(expando);
Console.WriteLine($"{specificProperty}: {specificValue}");
