Convert Dictionary To Anonymous Object?

Question

First, and to make things clearer I\'ll explain my scenario from the top:

I have a method which has the following signature:

public virtual void Send

If you have a class you want to covert the dictionary too, you can use the following to convert a dictionary to an object of that class:

Example class:

public class Properties1
{
    public string Property { get; set; }
}

The solution:

JavaScriptSerializer serializer = new JavaScriptSerializer();
Dictionary dict = new Dictionary { { "Property", "foo" } };
Properties1 properties = serializer.ConvertToType(dict);
string value = properties.Property;

You could also use a method like this to build the object from the dictionary, obviously this also requires you to have a class.

private static T DictionaryToObject(IDictionary dict) where T : new()
{
    T t = new T();
    PropertyInfo[] properties = t.GetType().GetProperties();

    foreach (PropertyInfo property in properties)
    {
        if (!dict.Any(x => x.Key.Equals(property.Name, 
            StringComparison.InvariantCultureIgnoreCase)))
            continue;
        KeyValuePair item = dict.First(x => x.Key.Equals(property.Name,
            StringComparison.InvariantCultureIgnoreCase));
        Type tPropertyType = t.GetType().GetProperty(property.Name).PropertyType;
        Type newT = Nullable.GetUnderlyingType(tPropertyType) ?? tPropertyType;
        object newA = Convert.ChangeType(item.Value, newT);
        t.GetType().GetProperty(property.Name).SetValue(t, newA, null);
    }
    return t;
}

However if you do not have the class you can create a dynamic object from a dictionary like this:

private static dynamic DictionaryToObject(Dictionary dict)
{
    IDictionary eo = (IDictionary)new ExpandoObject();
    foreach (KeyValuePair kvp in dict)
    {
        eo.Add(kvp);
    }
    return eo;
}

You can use it like this:

Dictionary dict = new Dictionary {{ "Property", "foo" }};
dynamic properties = DictionaryToObject(dict);
string value = properties.Property;
