FileHelpers:读取文件时如何处理带引号的字段 [英] FileHelpers: How to handle quoted fields when reading file

问题描述

这是我要读取的数据:

"Adam C. Emality","1Z620Y1V034826","14.40"
"Ethel Baeron","1Z620Y1V034604","15.19"
"Donna Lidt","1Z620Y1V034650","12.37"

然后在读入数据之后，我要对两个集合执行一个Join，一个集合为数组，一个为列表-我的代码在下面.但是，在执行读取的文件行之后，我的字符串就这样存储了"\"Adam C. Emality\"" "\"1Z620Y1V034826\"" "\"14.40\"" ...等.为什么会发生这种情况?我不想包含"，也不知道为什么要在\中添加.

Then after reading the data in, I want to perform a Join on the two collections, one an array and one a list - my code below. However after executing the read file line my strings are stored like this "\"Adam C. Emality\"" "\"1Z620Y1V034826\"" "\"14.40\""...etc.. Why is this happening? I do not want to include the " and I don't know why it is adding in a \.

namespace Amazon_File
{
    class SpreadSheet
    {
        public void create(IEnumerable<SpreadList> list)
        {


            var steamengine = new FileHelperEngine<Records>();
            var records = steamengine.ReadFile(@"C:\Users\Danny\Documents\Visual Studio 2013\Projects\Amazon File\Amazon File\Daniel.csv");

            var spreadlist = from x in list
                             join y in records on x.Name equals y.Name
                             select new { y.Name, y.Track, y.worldPrice, x.ItemPrice, x.Quantity };



[DelimitedRecord(",")]
    public class Records
    {

        public string Name;

        public string Track;

        public string worldPrice;
    }   

public class SpreadList
    {
        public string Name { get; set; }
        public string Title { get; set; }
        public string ItemPrice { get; set; }
        public string Quantity { get; set; }
    }
}

推荐答案

您必须添加[FieldQuoted]才能使库自动删除它们 http://www.filehelpers.net/docs/html/T_FileHelpers_FieldQuotedAttribute.htm

You must add [FieldQuoted] to make the library auto remove them http://www.filehelpers.net/docs/html/T_FileHelpers_FieldQuotedAttribute.htm

[DelimitedRecord(",")]
public class Records
{
    [FieldQuoted]
    public string Name;

    [FieldQuoted]
    public string Track;

    [FieldQuoted]
    public string worldPrice;
}
