Failed to write large amount of data to stream

Question

When I\'m trying to write very large amount of data (list with 300 000 rows and more) to memory stream using CsvHelper, it throws the exception \"System.IO.IOExcepti

Answer 1

Many thanks Spender, like he mentioned in the comment below the question, it has been fixed by replacing MemoryStream with FileStream and writing data direct into the file.

It was absolutely useless in my case to write data to MemoryStream and then copy it again into the file without any reason. Thanks him again for opening my eyes on that fact.

My fixed code below.

using (var fileStream = File.Create(path))
{
    using (var streamWriter = new StreamWriter(fileStream, encoding ?? Encoding.ASCII))
    {
        var csvWriter = new CsvWriter(streamWriter, GetConfiguration(delimiter, mappingClassType, mappingActions));
        csvWriter.WriteRecords(data);
    }
}

Now it works with any amount of input data.
