CSVWRITER.CONFIGURATION.ReferenceHeaderPrefix在较新版本的csvhelper中的等效物是什么？尝试此

csvwriter.configuration.referenceheaderprefix =（MemberType，MemberName）=＆gt; $“ {MemberName} _”;，

但不是让我，因为Referentheaderprefix仅在版本20.0.0之后才能获得方法

通常的工作流程是构建 csvconfiguration 类，然后将其传递到读者或作者的构造函数中。 And CsvConfiguration.ReferenceHeaderPrefix 确实具有SET方法。

var config = new CsvConfiguration(CultureInfo.InvariantCulture)
{
    ReferenceHeaderPrefix = (args) => $"{args.MemberName}_",
};
using (var writer = new StreamWriter("path\\to\\file.csv"))
using (var csv = new CsvWriter(writer, config))
{
    // Write your CSV records here.
    csv.WriteRecords(records);
}

还请注意，在当前版本（27.2.0）中， ReferenceHeaderPrefix 采用单个 referenctheaderprefixargs 参数，其中包含membertype and membername fields：

 公共读取的struct struct Referenceheaderprefixargs
{
  公共ReadOnly Type MemberType;

  公共Readonly字符串成员名称;

  public ReferenceHeaderPrefixargs（键入MemberType，字符串成员名称）
  {
      MemberType = MemberType;
      MemberName = MemberName;
  }
}

The usual workflow is to construct an instance of the CsvConfiguration class and pass that into the constructor for the reader or writer. And CsvConfiguration.ReferenceHeaderPrefix does have a set method.

var config = new CsvConfiguration(CultureInfo.InvariantCulture)
{
    ReferenceHeaderPrefix = (args) => quot;{args.MemberName}_",
};
using (var writer = new StreamWriter("path\\to\\file.csv"))
using (var csv = new CsvWriter(writer, config))
{
    // Write your CSV records here.
    csv.WriteRecords(records);
}

Note also that, in the current version (27.2.0), the ReferenceHeaderPrefix takes a single ReferenceHeaderPrefixArgs argument, which contains MemberType and MemberName fields:

public readonly struct ReferenceHeaderPrefixArgs
{
  public readonly Type MemberType;

  public readonly string MemberName;

  public ReferenceHeaderPrefixArgs(Type memberType, string memberName)
  {
      MemberType = memberType;
      MemberName = memberName;
  }
}
