否 headers 在 C# 中使用 Filehelpers FileHelperAsyncEngine

Question

自从从 FileHelperEngine 切换到 FileHelperAsyncEngine 后，似乎无法让 FileHelpers 库写入 headers。我根据文档调用了 GetFileHeader() 。有任何想法吗？

<!-- language: c# -->

var engine = new FileHelperAsyncEngine<ClaimModel>();
using (engine.BeginWriteFile(file))
{
    engine.HeaderText = engine.GetFileHeader();
    foreach (ClaimModel claim in claims)
    {
        engine.WriteNext(Utils.CleanStrings(claim));
    }
 }

   [FileHelpers.DelimitedRecord("|")]
    public class ClaimModel : Model
    {
        [FieldQuoted()]
        public string PolicyRef ;

您需要在BeginWriteFile()之前设置HeaderText。

var engine = new FileHelperAsyncEngine<ClaimModel>();
engine.HeaderText = engine.GetFileHeader();
using (engine.BeginWriteFile(file))
{
    foreach (ClaimModel claim in claims)
    {
        engine.WriteNext(Utils.CleanStrings(claim));
    }
}
