c# - 删除文件助手中的引号

Question

我有一个.csv文件（我无法控制数据），由于某种原因，它的所有内容都用引号引起来。

"Date","Description","Original Description","Amount","Type","Category","Name","Labels","Notes"
"2/02/2012","ac","ac","515.00","a","b","","javascript://"
"2/02/2012","test","test","40.00","a","d","c",""," "

我正在使用filehelpers，我想知道删除所有这些引号的最佳方法是什么？是否有句话说“如果我删除引号。如果找不到引号，则什么都不做”？

这会弄乱数据，因为我将在"\"515.00\""处加上不必要的多余引号（特别是因为在这种情况下，我希望它是一个小数而不是一个字符串”。

我也不确定“ javascript”的全部含义以及为什么生成它，但这来自我无法控制的服务。

编辑
这就是我使用csv文件的方式。

    using (TextReader textReader = new StreamReader(stream))
        {
            engine.ErrorManager.ErrorMode = ErrorMode.SaveAndContinue; 

            object[] transactions = engine.ReadStream(textReader);
        }

您可以使用在属性页面here上描述得最好的FieldQuoted属性。请注意，该属性可以应用于任何FileHelpers字段（即使它键入Decimal）。 （请记住，FileHelpers类描述了导入文件的规范。因此，当您将Decimal字段标记为FieldQuoted时，就是在文件中说，该字段会被引用。）

您甚至可以指定引号是否为可选

[FieldQuoted('"', QuoteMode.OptionalForBoth)] 

这是一个可以处理您的数据的控制台应用程序：

class Program
{
    [DelimitedRecord(",")]
    [IgnoreFirst(1)]
    public class Format1
    {
        [FieldQuoted]
        [FieldConverter(ConverterKind.Date, "d/M/yyyy")]
        public DateTime Date;
        [FieldQuoted]
        public string Description;
        [FieldQuoted]
        public string OriginalDescription;
        [FieldQuoted]
        public Decimal Amount;
        [FieldQuoted]
        public string Type;
        [FieldQuoted]
        public string Category;
        [FieldQuoted]
        public string Name;
        [FieldQuoted]
        public string Labels;
        [FieldQuoted]
        [FieldOptional]
        public string Notes;
    }

    static void Main(string[] args)
    {
        var engine = new FileHelperEngine(typeof(Format1));

        // read in the data   
        object[] importedObjects = engine.ReadString(@"""Date"",""Description"",""Original Description"",""Amount"",""Type"",""Category"",""Name"",""Labels"",""Notes""
""2/02/2012"",""ac"",""ac"",""515.00"",""a"",""b"","""",""javascript://""
""2/02/2012"",""test"",""test"",""40.00"",""a"",""d"",""c"","""","" """);

        // check that 2 records were imported
        Assert.AreEqual(2, importedObjects.Length);

        // check the values for the first record
        Format1 customer1 = (Format1)importedObjects[0];
        Assert.AreEqual(DateTime.Parse("2/02/2012"), customer1.Date);
        Assert.AreEqual("ac", customer1.Description);
        Assert.AreEqual("ac", customer1.OriginalDescription);
        Assert.AreEqual(515.00, customer1.Amount);
        Assert.AreEqual("a", customer1.Type);
        Assert.AreEqual("b", customer1.Category);
        Assert.AreEqual("", customer1.Name);
        Assert.AreEqual("javascript://", customer1.Labels);
        Assert.AreEqual("", customer1.Notes);

        // check the values for the second record
        Format1 customer2 = (Format1)importedObjects[1];
        Assert.AreEqual(DateTime.Parse("2/02/2012"), customer2.Date);
        Assert.AreEqual("test", customer2.Description);
        Assert.AreEqual("test", customer2.OriginalDescription);
        Assert.AreEqual(40.00, customer2.Amount);
        Assert.AreEqual("a", customer2.Type);
        Assert.AreEqual("d", customer2.Category);
        Assert.AreEqual("c", customer2.Name);
        Assert.AreEqual("", customer2.Labels);
        Assert.AreEqual(" ", customer2.Notes);
    }
}

（请注意，您的第一行数据似乎有8个字段，而不是9个字段，因此我用Notes标记了FieldOptional字段）。
