.net - DateTime.ToString() 显示子午线为 "A.M."或 "P.M."

Question

有什么办法可以使用DateTime.ToString()方法将时间部分的子午线显示为“A.M.”而不是“AM”？我尝试使用面具“t.t.”但这只是输出“A.A.”

Answer 1

您可以重新定义 AMDesignator和 PMDesignator CultureInfo.DateTimeFormat 的属性，然后将文化指定为格式提供程序:

using System;
using System.Globalization;

class Program {
    public static void Main() {
        CultureInfo c = (CultureInfo)CultureInfo.CurrentCulture.Clone();
        c.DateTimeFormat.AMDesignator = "A.M.";
        c.DateTimeFormat.PMDesignator = "P.M.";
        Console.WriteLine(DateTime.Now.ToString("tt",c));
    }
}
