使用Moment()和Linq时日期无效

// 示例：使用 moment() 解析日期字符串
let dateStr = "2023-10-01";
let date = moment(dateStr, "YYYY-MM-DD");
if (!date.isValid()) {
    console.error("日期无效");
} else {
    console.log("日期有效:", date.format("YYYY-MM-DD"));
}

// 示例：使用 moment.utc() 处理 UTC 时间
let dateStr = "2023-10-01T12:00:00Z";
let date = moment.utc(dateStr);
if (!date.isValid()) {
    console.error("日期无效");
} else {
    console.log("日期有效:", date.format("YYYY-MM-DD HH:mm:ss"));
}

// 示例：LINQ 查询中的日期比较
using System;
using System.Linq;

public class Example
{
    public static void Main()
    {
        var dates = new List<string> { "2023-10-01", "2023-10-02", "2023-10-03" };
        DateTime targetDate = DateTime.Parse("2023-10-02");

        var result = dates.Where(dateStr => DateTime.Parse(dateStr) == targetDate).ToList();
        Console.WriteLine(string.Join(", ", result));
    }
}
