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?

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);
