Creating an anonymous type dynamically? [duplicate]

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?

Answer 1

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);
