    if (source == null) ThrowExceptionWhenSourceArgumentIsNull();

    var dictionary = new Dictionary<string, T>();
    foreach (PropertyDescriptor property in TypeDescriptor.GetProperties(source))

      {
        dictionary.Add(property.Name, (T)value);

Just a typo needs to be fixed
dictionary.add(property.Name, (T)value);
should be
dictionary.Add(property.Name, (T)value);
Line 24
