我有一个csv文件，我需要在json中将该数据转换为json格式。我试图读取文件并获取数据，并用逗号（，）分隔符分割。然后将该数据转换为json格式。但结果并不是预期的结果。因为列值具有多个（，）分隔符。
任何人都可以帮我解决这个问题吗？
我的代码如下：
string targetFile = @"C:\Users\grajaji\Desktop\target.csv";
var csv = new List<string[]>();
var lines = System.IO.File.ReadAllLines(targetFile);
foreach (string line in lines)
csv.Add(line.Split(','));
var json = JsonConvert.SerializeObject(csv);
return Request.CreateResponse(HttpStatusCode.OK, json);
结果是：

答案 0 :(得分：0)
简单的CSV解析器我真的不知道它会有多快。
//You should allways reuse the regex objects since createing them can be slow
private static readonly Regex regex = new Regex(",(?=(?:[^\"]*\"[^\"]*\")*(?![^\"]*\"))");
static void Main(string[] args)
{
//Some csv data
var csv =
@"H1,H2,H3
1,""ASd, asdasd, asda"", asd
1,""ASd, asdasd, asda"", asd
1,""ASd, asdasd, asda"", asd";
//Gets the lines from csv you can use the ReadAllLines
var lines = csv.Split(new[] { "\r\n", "\r", "\n" }, StringSplitOptions.RemoveEmptyEntries);
//In csv the first row can indicate the headers like in you case
var headers = regex.Split(lines.First()).Select((name,index) => new { name, index });
//Skip Header data and split the rest of the string
var items = from line in lines.Skip(1)
let data = regex.Split(line)
select headers.ToDictionary(i => i.name, i=> data[i.index]);
//Simple way to create JSON string can be optimised if you need high performance
Console.WriteLine(JsonConvert.SerializeObject(items, Formatting.Indented));
Console.ReadLine();
}
但你真的应该发布原始的CSV，因为csv是非标准的。
