c# – .NET(3.5)使用点而不是冒号格式化时间作为IT文化的TimeSep

The 24-hour notation is used in writing with a colon as a separator.
Example: 14:05. The minutes are written with two digits; the hour
numbers can be written with or without leading zero.

但是,运行以下代码似乎输出点：

using System.Globalization;

Thread.CurrentThread.CurrentCulture = new CultureInfo("it-IT");
Thread.CurrentThread.CurrentUICulture = new CultureInfo("it-IT");
// Outputs "11.08"
Console.WriteLine(DateTime.Now.ToShortTimeString());

// Outputs "."
Console.WriteLine(new CultureInfo("it-IT").DateTimeFormat.TimeSeparator);

这是一个框架错误吗？什么是“修复”它的最佳方法？ TimeSeparator是可设置的 – 我们应该在分配给Thread.CurrentThread.CurrentCulture等之前覆盖它吗？
