CSV Helper 在定界符后将字符串字段“名称”包裹到双引号中？

Question

我的文件中的 CSV 结果有一些问题，我已经用代码编写了下一个配置（我正在使用 CSVHelper 库）

public class ReportModelMap : ClassMap<ReportModel>
{
    public ReportModelMap()
    {
        Map(x => x.Name).Index(9).Name(" Name");
    }
}

客户要求在 'Name' 文本 => "名称" 之间添加 space。但是，库将字符串包装到 'Name' 中并用双引号引起来，对我来说，这是错误的行为。我怎样才能让--Surname; Name-- instead of --Surname;"Name"--?

我在 CsvWriter 中找不到任何特定的配置来修复它

我的储蓄逻辑，如果需要的话

using (var writer = new StreamWriter(path))
using (var csvWriter = new CsvWriter(writer, CultureInfo.InvariantCulture))
{
   csvWriter.Configuration.RegisterClassMap<ReportModelMap>();
   csvWriter.Configuration.Delimiter = ";";

   csvWriter.WriteRecords(ratingModels);
}

@Panagiotis Kanavos 是正确的。您可以使用 ShouldQuote 仅覆盖该标题的引用行为。

void Main()
{
    var ratingModels = new List<ReportModel>
    {
        new ReportModel { Id = 1, Surname = "Surname", Name = " Name" } 
    };
    
    //using (var writer = new StreamWriter(path))
    using (var csvWriter = new CsvWriter(Console.Out, CultureInfo.InvariantCulture))
    {
        csvWriter.Configuration.RegisterClassMap<ReportModelMap>();
        csvWriter.Configuration.Delimiter = ";";
        csvWriter.Configuration.ShouldQuote = (field, context) => 
        {
            if (!context.HasHeaderBeenWritten && field == " Name") 
            {
                return false;
            } 
            else 
            {
                return ConfigurationFunctions.ShouldQuote(field, context); 
            }
        };

        csvWriter.WriteRecords(ratingModels);
    }
}

// You can define other methods, fields, classes and namespaces here
public class ReportModelMap : ClassMap<ReportModel>
{
    public ReportModelMap()
    {
        Map(x => x.Id).Index(0);
        Map(x => x.Surname).Index(1);
        Map(x => x.Name).Index(2).Name(" Name");
    }
}

public class ReportModel
{   
    public int Id { get; set; }
    public string Surname { get; set; }
    public string Name { get; set; }
}
