我必须使用什么属性才能使用 CsvReader 读取这些日期字段？

Question

我的 CSV 文件有一个名为 Date 的字段。此列中的值的类型为 dd/mm/yyyy.

例如：

08/01/2022

目前我在 CsvReader class 中将其映射到 string:

public class CLMExplorerHistory
{
    [Name("Date")]
    public string Date { get; set; }
}

我已经测试读取我的 CSV 文件（显然有更多信息列）：

public void Test2()
{
    string strPath = "d:\Import CLM\Calendar Simon.csv";

    if (!File.Exists(strPath))
        return;

    try
    {
        using (var reader = new StreamReader(strPath))
        using (var csv = new CsvReader(reader, CultureInfo.InvariantCulture))
        {
            var records = csv.GetRecords<CLMExplorerHistory>();

            foreach (var record in records)
            {
                SimpleLog.Log(record.Date);
            }
        }
    }
    catch (System.Exception ex)
    {
        SimpleLog.Log(ex);
    }
}

我检查了日志，一切正常：

我可以向我的属性添加什么属性以便它可以成为 DateTime 对象？我不想使用 map，而是使用属性限定符。

Answer 1

相当确定

[Format("dd/MM/yyyy")]
[Name("Date")]
public DateTime Date { get; set; }

..但是如果我记错了请告诉我，这完全是胡说八道

从技术上讲，如果 prop 的名称相同，则 Name 属性是不必要的，但我确信给属性一个更具描述性的名称在待办事项列表中名列前茅，因此我将其保留下来更容易

我必须使用什么属性才能使用 CsvReader 读取这些日期字段？

What attribute must I use to read in these date fields using CsvReader?

c#

datetime

csvreader
