Question

我有一个歌曲的CSV文件，信息用逗号分隔，我想将它们转换为班级列表（见下面的课程）。

抱歉，如果我不能很好地解释

例如：

Waiting For Love,Avicii,Tanecni Liga 171,Dance & House,Avicii,,1,2015,,,,

问题是我有一些带引号的歌曲，引号内有逗号例如：

Hey Brother,Avicii,TRUE,House,Avicii,,3 of 12,2013,,,"Tim Bergling, Ash Pournouri, Vincent Pontare & Salem Al Fakir",

问题是我想要的 - “Tim Bergling，Ash Pournouri，Vincent Pontare和Salem Al Fakir”将是一个字符串，但如果我用逗号分裂，我在这里发现它会切入中间我不想要的字符串

如果我在这一行使用Split(',');，它会执行此操作：

Hey Brother
Avicii
TRUE
House
Avicii
//empty string because there is ',,'
3 of 12
2013
//empty string because there is ',,'
//empty string because there is ',,'
"Tim Bergling
 Ash Pournouri
 Vincent Pontare & Salem Al Fakir"
//empty string because there is ',,'

相反，我想要这个：

Hey Brother
Avicii
TRUE
House
Avicii
//empty string because there is ',,'
3 of 12
2013
//empty string because there is ',,'
//empty string because there is ',,'
Tim Bergling, Ash Pournouri, Vincent Pontare & Salem Al Fakir
//empty string because there is ',,'

这是我的歌曲课程：

    `public class song
    {
        private string name; // Name of the song
        private string artist; // Name of the artist
        private string album; // The name of the album
        private string genre; // The Genre of the song
        private string album_Artist; // Artist name of the album
        private string release_Date; // The release date of the song
        private string track; // The number of the track of the number of the count of the tracks - a.k 4 of 12
        private string year; // The year that the song came
        private string comments; // The comments for the song
        private string description; // The description for the song
        private string composer; // The composer of the song;
        private string grouping; // The grouping of the song
    }

我为每个字符串设置了Get和Set（我剪切它们因为它太长了）

不使用任何特殊库，您只需在C＃代码中引用Microsoft.VisualBasic，并按照以下使用TextFieldParser

（从https://stackoverflow.com/a/3508572/1658434复制）

using (TextFieldParser parser = new TextFieldParser(@"c:\temp\test.csv"))
{
    parser.TextFieldType = FieldType.Delimited;
    parser.SetDelimiters(",");
    while (!parser.EndOfData) 
    {
        //Processing row
        string[] fields = parser.ReadFields();
        foreach (string field in fields) 
        {
            //TODO: Process field
        }
    }
}

我已经使用您的示例测试了它，它可以根据您的需要运行。
