有没有办法使用 Microsoft.VisualBasic.FileIO 的 TextFieldParser 将 .csv 文件中的所有空字段映射为 NULL

Question

I am working on a C# console application. and I am reading a .csv file using Microsoft.VisualBasic.FileIO package. as follow:-

class Program
{
    static void Main(string[] args)
    {
        Entities entities = new Entities();
        TextFieldParser parser = new TextFieldParser(@"C:\My.csv");

        parser.TextFieldType = FieldType.Delimited;
        parser.SetDelimiters(",");
        while (!parser.EndOfData)
        {
            string[] fields = parser.ReadFields();

Can I define to map any empty .csv cell as NULL? For example, currently I can trim all the values doing specifying this:

parser.TrimWhiteSpace = true;

Can I set the parser to map any empty cell as Null ?

Thanks

as per @Hans answer No, turning empty strings into NULL is your job. – Hans Passant yesterday
