See my original answer https://stackoverflow.com/a/12603828/1171321

Basically combine my method in my blog post and the TryValidateProperty() suggestion to maintain model validation annotations.

Edit: I went ahead and worked up a code enhancement to my code in the blog post. I'm going to post this updated code shortly. Here is a simple example that validates each property and gives you access to an array of the results. Just a sample of one approach

public class FileUpload
{
    private readonly string _RawValue;

    public T Value { get; set; }
    public string FileName { get; set; }
    public string MediaType { get; set; }
    public byte[] Buffer { get; set; }

    public List ValidationResults = new List(); 

    public FileUpload(byte[] buffer, string mediaType, string fileName, string value)
    {
        Buffer = buffer;
        MediaType = mediaType;
        FileName = fileName.Replace("\"","");
        _RawValue = value;

        Value = JsonConvert.DeserializeObject(_RawValue);

        foreach (PropertyInfo Property in Value.GetType().GetProperties())
        {
            var Results = new List();
            Validator.TryValidateProperty(Property.GetValue(Value),
                                          new ValidationContext(Value) {MemberName = Property.Name}, Results);
            ValidationResults.AddRange(Results);
        }
    }

    public void Save(string path, int userId)
    {
        if (!Directory.Exists(path))
        {
            Directory.CreateDirectory(path);
        }
        var SafeFileName = Md5Hash.GetSaltedFileName(userId,FileName);
        var NewPath = Path.Combine(path, SafeFileName);
        if (File.Exists(NewPath))
        {
            File.Delete(NewPath);
        }

        File.WriteAllBytes(NewPath, Buffer);

        var Property = Value.GetType().GetProperty("FileName");
        Property.SetValue(Value, SafeFileName, null);
    }
}
