动态地去除为Expando /动态对象的成员 [英] Dynamically removing a member from Expando /dynamic object

问题描述

我正在寻找一种方式来从动态对象动态删除成员（可能是我们可以使用Expando的对象吗？）。

I'm looking for a way to remove members dynamically from an dynamic object (may be can we use Expando object here?).

OK，我想是需要一点澄清...

OK, I guess a little clarification is needed...

当你做到这一点：

dynamic foo = new ExpandoObject();
foo.Bar = 42;
foo.Jar = 25;

的

酒吧，'罐子'属性将在运行时动态添加。我显示该用户，他还可以加入自己的属性（表格可选项），这可以通过仅仅增加成员动态对象来完成。

The Bar, 'jar' property will be added dynamically at runtime. I am displaying this to user , he may further add his own properties (form available option), this can be done by just adding member to dynamic object.

但他也可以删除成员（说'罐'）形成Foo对象，我们怎么删除成员形成动态对象？可我们这里使用了Expando对象？

But he can also remove members (say 'Jar') form the Foo object, how do we remove the member form dynamic object? Can we use Expando object here?

推荐答案

可以治疗的 ExpandoObject 作为的IDictionary<string，对象> 代替，然后将其删除这种方式：

You can treat the ExpandoObject as an IDictionary<string, object> instead, and then remove it that way:

IDictionary<string, object> map = foo;
map.Remove("Jar");
