动态对象属性操作

需求是能够动态修改属性的值，但是这个对象不是具体的model对象

做法是借用DynamicObject对象来处理。

第一步，创建一个对象来继承DynamicObject

public class DynamicDictionary : DynamicObject
    {
        // The inner dictionary.
        Dictionary<string, object> dictionary
            = new Dictionary<string, object>();

        // This property returns the number of elements
        // in the inner dictionary.
        public int Count
        {
            get
            {
                return dictionary.Count;
            }
        }

        // If you try to get a value of a property 
        // not defined in the class, this method is called.
        public override bool TryGetMember(
            GetMemberBinder binder, out object result)
        {
            // Converting the property name to lowercase
            // so that property names become case-insensitive.
            string name = binder.Name.ToLower();

            // If the property name is found in a dictionary,
            // set the result parameter to the property value and return true.
            // Otherwise, return false.
            return dictionary.TryGetValue(name, out result);
        }

        // If you try to set a value of a property that is
        // not defined in the class, this method is called.
        public override bool TrySetMember(
            SetMemberBinder binder, object value)
        {
            // Converting the property name to lowercase
            // so that property names become case-insensitive.
            dictionary[binder.Name.ToLower()] = value;

            // You can always add a value to a dictionary,
            // so this method always returns true.
            return true;
        }
    }

第二步，定义一个dynamic类型的变量，然后用这个对象进行实例化

dynamic data = new DynamicDictionary();
data.Url = "XXX";

这里的Url就是属性，至少编译的时候，这样写会通过，并且在执行的时候，会自动获取到这个属性，接下来就可以进行编辑了。
