如何拆分列可能包含的csv，8个答案

I am not really good in Regex.

我在Regex中并不擅长。

The string:

字符串：

"FF","asdadasd60","Report,License","502","5A1301","I-Web Report,License","50A1","PR02","02","5A11","REL","","","","A1170600","500008","FA10","5000001","","","","","000000000.000","","000000000.000","","000000000.000","","000000000.000","","00000000","00000000","",""

I have done this but remove the double quotes before. But the result for string Report,License and I-Web Report,License are splitted. This is wrong.

我已经这样做了，但之前删除了双引号。但字符串报告，许可证和I-Web报告，许可证的结果是分开的。这是错的。

I want to split it into array by comma between double quotes not inside them.

我想用双引号之间的逗号将它拆分成数组。

Use a real csv parser instead of using string methods or regex. You could use the TextFieldParser which is the only one available in the framework directly:

使用真正的csv解析器而不是使用字符串方法或正则表达式。您可以使用TextFieldParser，它是框架中唯一可用的直接：

var allLineFields = new List<string[]>();
using (var parser = new Microsoft.VisualBasic.FileIO.TextFieldParser(new StringReader(str)))
{
    parser.Delimiters = new string[] { "," };
    parser.HasFieldsEnclosedInQuotes = true; // <--- !!!
    string[] lineFields;
    while ((lineFields = parser.ReadFields()) != null)
    {
        allLineFields.Add(lineFields);
    }
}

You need to add a reference to the Microsoft.VisualBasic dll to your project.

您需要向项目添加对Microsoft.VisualBasic dll的引用。

There are other available: Parsing CSV files in C#, with header

还有其他可用：使用标头解析C＃中的CSV文件
