未执行计算以计算c#asp.net sql linq中两个日期之间的总天数差。

public class DateModel
{
    public DateTime StartDate { get; set; }
    public DateTime EndDate { get; set; }
}

using System;
using System.Collections.Generic;
using System.Linq;

public class Program
{
    public static void Main()
    {
        // 假设你有一个DateModel的列表
        List<DateModel> dateModels = new List<DateModel>
        {
            new DateModel { StartDate = new DateTime(2023, 1, 1), EndDate = new DateTime(2023, 1, 10) },
            new DateModel { StartDate = new DateTime(2023, 2, 1), EndDate = new DateTime(2023, 2, 10) }
        };

        // 使用LINQ计算每个日期范围的天数差
        var dateDifferences = dateModels.Select(dm => (dm.EndDate - dm.StartDate).TotalDays);

        // 输出结果
        foreach (var days in dateDifferences)
        {
            Console.WriteLine($"Total days difference: {days}");
        }
    }
