Creating an anonymous type dynamically?

Question

I wanna create an anonymous type that I can set the property name dynamically. it doesn't have to be an anonymous type. All I want to achieve is set any objects property names dynamically. It can be ExpandoObject, but dictionary will not work for me. What are your suggestions?

Accepted Answer

Only `ExpandoObject` can have dynamic properties.

Edit: Here is an example of Expand Object usage (from its MSDN description):

```
dynamic sampleObject = new ExpandoObject();
sampleObject.TestProperty = "Dynamic Property"; // Setting dynamic property.
Console.WriteLine(sampleObject.TestProperty );
Console.WriteLine(sampleObject.TestProperty .GetType());
// This code example produces the following output:
// Dynamic Property
// System.String

dynamic test = new ExpandoObject();
((IDictionary<string, object>)test).Add("DynamicProperty", 5);
Console.WriteLine(test.DynamicProperty);
```
