Forced Int32

Hello Mark,

I noticed an exception on below : {"Value must be non-negative and less than or equal to Int32.MaxValue. (Parameter 'count')"}

This is caused duet o the fact that one value is well above int32 range, although i though that it would be mapped as string?, those values are decimal in .xslb. spreadsheet. Value : “-11001000000”

I tried both mapping fields as decimal?, decimal. In my JoinHeaders() method, non of this worked. Once line was manually removed all worked fine.

        private List<T>? SylvanReader<T>()
        {
            try
            {
                var options = new SylExcel.ExcelDataReaderOptions { Schema = SylExcel.ExcelSchema.Default, GetErrorAsNull = true };
                //collect data
                using (SylExcel.ExcelDataReader excelDataReader = SylExcel.ExcelDataReader.Create(Setup.FilePath, options))
                {
                    //loop to locate needed sheet from passed setup
                    while (excelDataReader.WorksheetName != Setup.SheetName)
                    {
                        excelDataReader.NextResult();

                        if (excelDataReader.WorksheetName == null)
                        {
                            //throw exception, that sheet was not located
                            throw new Exception(string.Format("Didn't find the sheet: {0}", Setup.SheetName));
                        }
                    }
                    //loop to find headers, this will allow to skip unwanted rows, such as comments, empty lines etc.
                    for (int i = 0; i < Setup.StartRow; i++)
                    {
                        excelDataReader.Read();
                    }
                    //get all coulmns in file to column specified as max
                    //JoinHeaders is a method that returns array of needed sheets, and not needed as int. 
                    //excample: Data1, Data2, 2, 3, Data3, 5 as string 
                    var schema = Schema.Parse(Setup.JoinHeaders());

                    excelDataReader.InitializeSchema(schema.GetColumnSchema(), useHeaders: true);

                    //JoinHeaders is a method that returns only array of needed sheets. 
                    //excample: Data1, Data2, Data3 as string[]
                    var dataReader = excelDataReader.Select(Setup.NeededHeaders());
                    var binderOptions = new DataBinderOptions
                    {
                        InferColumnTypeFromMember = true,
                        BindingMode = DataBindingMode.Any
                    };
                    DataBinder.Create<T>(dataReader, binderOptions);
                    return dataReader.GetList<T>().ToList();
                }
            }
            catch(Exception ex)
            {
                throw new Exception(ex.Message);
            }
        }

Okay, this ended up being a bug with reading records that span an internal buffer boundary. Just pushed 0.1.8 to nuget which contains the fix.

Okay, I can repro the exception with the file you sent. Will take a look and figure out what’s going on. Definitely a bug, but it isn’t obvious right away. Might not be able to investigate it right away, but I will try to look at it in the next few days.
