如何从appsettings.json获得日期时间?

Question

我有。net core 5.0应用程序，并尝试从appsettings.json中获取DateTime

appsettings.json:

"TimeModel": {
"RestartDuration": "27.10.2021 12:30:00"
}

代码:

services.Configure<TimeModel>(
configuration.GetSection("TimeModel"));

错误:

System.InvalidOperationException: Failed to convert configuration value at 'TimeModel:RestartDuration' to type 'System.DateTime'.
---> System.FormatException: 27.10.2021 12:30:00 is not a valid value for DateTime.
---> System.FormatException: String '27.10.2021 12:30:00' was not recognized as a valid DateTime.

有几种方法可以做到:

1. 获取日期作为字符串，然后解析:DateTime.Parse(configuration.GetValue<string>("Date"))
2. 可直接获取:configuration.GetValue<DateTime>("TimeModel")
您可以使用类模型。

在所有情况下，您需要确保日期的格式默认为:2021-10-27T12:30:00。
