hello I'm trying to use this package to interface with Sick Lidars. I'm trying to read int data in a hexadecimal ASCII string

Normal running code:

public class OutputChannel
{
        [FieldOrder(0)]
        [SerializeAs(SerializedType.TerminatedString, StringTerminator = (char)0x20)]
        public string DataAmount { get; set; }

        //数据列表
        [FieldOrder(1)]
        [FieldCount(nameof(DataAmount), ConverterType = typeof(StringLengtConvert))]
        public List<DistData> DistDatas{ get; set; }
}
public class DistData
  {
      [SerializeAs(SerializedType.TerminatedString, StringTerminator = (char)0x20)]
      public string Data { get; set; }
  }
 class StringLengtConvert : IValueConverter
    {
        // Read
        public object Convert(object value, object parameter, BinarySerializationContext context)
        {
            return (System.Convert.ToInt32((string)value,16) + System.Convert.ToInt32(parameter));
        }
        //Write
        public object ConvertBack(object value, object parameter, BinarySerializationContext context)
        {
            return (System.Convert.ToInt32(value) - System.Convert.ToInt32(parameter));
        }
    }

I want to change string to int:

public class DistData
  {
      [SerializeAs(SerializedType.TerminatedString, StringTerminator = (char)0x20, ConverterType = typeof(StringLengtConvert))]
      public int Data { get; set; }
  }

I looked at BinarySerialization.Graph.ValueGraph class's method Deserialize, when the code ConvertToFieldType (value). IValueConverter or Convet Format is not supported

Can you convert the hex to binary first? I think it would be easier to process then.

I have created a small test

I want to change DataAmount,DistData.Data to int type

    [TestClass]
    public class Issue199Tests : TestBase
    {
        BinarySerializer serializer = new BinarySerializer();
        [TestMethod]
        public void Test()
        {

            var testdata = "A ED7 F13 F25 F26 EBC E82 E60 E43 DD9 DC3 DC4 ";
            var stringToByte = StringToByte(testdata);

            var outputChannel = serializer.Deserialize<OutputChannel>(stringToByte);

            // TestContext.Out.WriteLine(JsonConvert.SerializeObject(outputChannel));

            Assert.AreEqual(Convert.ToInt32(outputChannel.DataAmount, 16), outputChannel.DistDatas.Count);
            Assert.AreEqual(Convert.ToInt32("ED7", 16), Convert.ToInt32(outputChannel.DistDatas[0].Data, 16));
        }
 public static byte[] StringToByte(string str)
        {
            byte[] bytes = new byte[str.Length];
            for (int i = 0; i < str.Length; i++)
            {
                bytes[i] = (byte)str[i];
            }

            return bytes;
        }

       public class OutputChannel
{
    [FieldOrder(0)]
    [SerializeAs(SerializedType.TerminatedString, StringTerminator = (char)0x20)]
    public string DataAmount { get; set; }

    //数据列表
    [FieldOrder(1)]
    [FieldCount(nameof(DataAmount), ConverterType = typeof(StringLengtConvert))]
    public List<DistData> DistDatas { get; set; }
}

public class DistData
{
    [SerializeAs(SerializedType.TerminatedString, StringTerminator = (char)0x20)]
    public string Data { get; set; }
}

class StringLengtConvert : IValueConverter
{
    // Read
    public object Convert(object value, object parameter, BinarySerializationContext context)
    {
        return (System.Convert.ToInt32((string)value, 16) + System.Convert.ToInt32(parameter));
    }

    //Write
    public object ConvertBack(object value, object parameter, BinarySerializationContext context)
    {
        return (System.Convert.ToInt32(value) - System.Convert.ToInt32(parameter));
    }
}
    }
