c# 调整CultureInfo 全局修改时间格式

// 克隆一个现有的文化
CultureInfo customCulture = (CultureInfo)CultureInfo.GetCultureInfo("zh-CN").Clone();

// 修改时间显示格式
customCulture.DateTimeFormat.ShortDatePattern = "yyyy$MM$dd";
customCulture.DateTimeFormat.LongDatePattern = "yyyy$MM$dd";
customCulture.DateTimeFormat.ShortTimePattern = "HH$mm";
customCulture.DateTimeFormat.LongTimePattern = "HH$mm$ss";

// 设置全局文化
CultureInfo.DefaultThreadCurrentCulture = customCulture;
CultureInfo.DefaultThreadCurrentUICulture = customCulture;

// 测试输出
Console.WriteLine(DateTime.Now);
