Add property to ExpandoObject with the same name as a string

Question

Is there a way to add a property to an ExpandoObject with the same name as a string value?

For example, if I have:

string propName = \"ProductNumber\";
d         


        

Answer 1

Cast the ExpandoObject to an IDictionary to do this:

string propName = "ProductNumber";
dynamic obj = new System.Dynamic.ExpandoObject();
var dict = (IDictionary)obj;
dict[propName] = 123;
