如何将JSON转换为TimeSpan c#

创建您自己的类并将其反序列化为。然后将其转换为 TimeSpan .

internal class Program
{
    static void Main(string[] args)
    {
        var options = new JsonSerializerOptions { PropertyNameCaseInsensitive = true };
        var json =
            """
            { "seconds": 60, "days": 5 }
            """;

        var timeSpan = JsonSerializer.Deserialize<MyTimeSpan>(json, options)?.ToTimeSpan();
    }

    public class MyTimeSpan
    {
        public int Seconds { get; set; }
        public int Minutes { get; set; }
        public int Hours { get; set; }
        public int Days { get; set; }

        public TimeSpan ToTimeSpan() => new(Days, Hours, Minutes, Seconds);
    }
}

using System;
using System.Text.Json;
public class JsonTimeSpanConverter
{
public TimeSpan ConvertJsonToTimeSpan(string json)
{
    var jsonDocument = JsonDocument.Parse(json);
    var root = jsonDocument.RootElement;

    int days = root.TryGetProperty("days", out var daysElement) ? daysElement.GetInt32() : 0;
    int hours = root.TryGetProperty("hours", out var hoursElement) ? hoursElement.GetInt32() : 0;
    int minutes = root.TryGetProperty("minutes", out var minutesElement) ? minutesElement.GetInt32() : 0;
    int seconds = root.TryGetProperty("seconds", out var secondsElement) ? secondsElement.GetInt32() : 0;
    int milliseconds = root.TryGetProperty("milliseconds", out var millisecondsElement) ? millisecondsElement.GetInt32() : 0;

    return new TimeSpan(days, hours, minutes, seconds, milliseconds);
}
}

JsonTimeSpanConverter类包含一个方法ConvertJsonToTimeSpan,该方法以JSON字符串作为输入,并提取相关的时间组件(天、小时、分钟、秒和毫秒)来创建TimeSpan对象。代码使用系统。文本用于解析Json数据的Json命名空间。
