隐式运算符和TypeConverters是等价的吗？

public static implicit operator int(MyClass myClass)
{
    return myClass.Value;
}

public class MyTypeConverter : TypeConverter
{
    public override bool CanConvertFrom(ITypeDescriptorContext context, Type sourceType)
    {
        return sourceType == typeof(string);
    }

    public override object ConvertFrom(ITypeDescriptorContext context, CultureInfo culture, object value)
    {
        return new MyClass((string)value);
    }
}
