如何在枚举值未解析时将枚举处理为字符串绑定失败

public enum Color { Red, Green, Blue }

public string GetColorString(Color color)
{
    switch (color)
    {
        case Color.Red:
            return "Red";
        case Color.Green:
            return "Green";
        case Color.Blue:
            return "Blue";
        default:
            return "Unknown";
    }
}

public enum Color
{
    [Description("红色")]
    Red,
    [Description("绿色")]
    Green,
    [Description("蓝色")]
    Blue
}

public string GetColorString(Color color)
{
    var fieldInfo = color.GetType().GetField(color.ToString());
    var attributes = (DescriptionAttribute[])fieldInfo.GetCustomAttributes(typeof(DescriptionAttribute), false);
    return attributes.Length > 0 ? attributes[0].Description : color.ToString();
}

public class ColorSerializer
{
    public static string Serialize(Color color)
    {
        switch (color)
        {
            case Color.Red:
                return "Red";
            case Color.Green:
                return "Green";
            case Color.Blue:
                return "Blue";
            default:
                throw new ArgumentException("Unknown color");
        }
    }

    public static Color Deserialize(string value)
    {
        switch (value)
        {
            case "Red":
                return Color.Red;
            case "Green":
                return Color.Green;
            case "Blue":
                return Color.Blue;
            default:
                throw new ArgumentException("Unknown color value");
        }
    }
}
