Here is a sample helper class which converts an Object and returns an Expando with all public properties of the given object.
public static class dynamicHelper
{
public static ExpandoObject convertToExpando(object obj)
{
//Get Properties Using Reflections
BindingFlags flags = BindingFlags.Public | BindingFlags.Instance;
PropertyInfo[] properties = obj.GetType().GetProperties(flags);
//Add Them to a new Expando
ExpandoObject expando = new ExpandoObject();
foreach (PropertyInfo property in properties)
{
AddProperty(expando, property.Name, property.GetValue(obj));
}
return expando;
}
public static void AddProperty(ExpandoObject expando, string propertyName, object propertyValue)
{
//Take use of the IDictionary implementation
var expandoDict = expando as IDictionary;
if (expandoDict.ContainsKey(propertyName))
expandoDict[propertyName] = propertyValue;
else
expandoDict.Add(propertyName, propertyValue);
}
}
Usage:
//Create Dynamic Object
dynamic expandoObj= dynamicHelper.convertToExpando(myObject);
//Add Custom Properties
dynamicHelper.AddProperty(expandoObj, "dynamicKey", "Some Value");
