问ReadStreamAsDT - filehelpers和C# -如何使用Filehelpers动态读取CSV？

EN

private static DataTable CreateDataTableFromFile(byte[] importFile) {
    var cb = new DelimitedClassBuilder("temp", ",") { IgnoreFirstLines = 0, IgnoreEmptyLines = true, Delimiter = "," };
    var ms = new MemoryStream(importFile); 
    var sr = new StreamReader(ms); 
    var headerArray = sr.ReadLine().Split(',');
    foreach (var header in headerArray) { 
        cb.AddField(header, typeof(string)); 
        cb.LastField.FieldQuoted = true; 
        cb.LastField.QuoteChar = '"'; 
    }
    var engine = new FileHelperEngine(cb.CreateRecordClass());
    return engine.ReadStreamAsDT(sr);
}
