法律研究C# 中的 DateTime.GetDateTimeFormats() 方法
C# 中的 DateTime.GetDateTimeFormats() 方法用于将该实例的值转换为标准日期和时间格式说明符支持的所有字符串表示形式。
语法
以下是语法 −
public string[] GetDateTimeFormats () public string[] GetDateTimeFormats (char ch);
上面，ch 是一个标准的日期和时间格式字符串。
示例
现在我们来看一个示例，来实现 DateTime.GetDateTimeFormats() 方法 −
using System;
public class Demo {
public static void Main() {
DateTime d = new DateTime(2019, 11, 10, 7, 20, 45);
string[] res = d.GetDateTimeFormats();
foreach(string s in res)
Console.WriteLine(s);
}
}输出
这将生成以下输出 −
11/10/2019 11/10/19 11/10/19 11/10/2019 19/11/10 2019-11-10 10-Nov-19 Sunday, November 10, 2019 November 10, 2019 Sunday, 10 November, 2019 10 November, 2019 Sunday, November 10, 2019 7:20 AM Sunday, November 10, 2019 07:20 AM Sunday, November 10, 2019 7:20 Sunday, November 10, 2019 07:20 November 10, 2019 7:20 AM November 10, 2019 07:20 AM November 10, 2019 7:20 November 10, 2019 07:20 Sunday, 10 November, 2019 7:20 AM Sunday, 10 November, 2019 07:20 AM Sunday, 10 November, 2019 7:20 Sunday, 10 November, 2019 07:20 10 November, 2019 7:20 AM 10 November, 2019 07:20 AM 10 November, 2019 7:20 10 November, 2019 07:20 Sunday, November 10, 2019 7:20:45 AM Sunday, November 10, 2019 07:20:45 AM Sunday, November 10, 2019 7:20:45 Sunday, November 10, 2019 07:20:45 November 10, 2019 7:20:45 AM November 10, 2019 07:20:45 AM November 10, 2019 7:20:45 November 10, 2019 07:20:45 Sunday, 10 November, 2019 7:20:45 AM Sunday, 10 November, 2019 07:20:45 AM Sunday, 10 November, 2019 7:20:45 Sunday, 10 November, 2019 07:20:45 10 November, 2019 7:20:45 AM 10 November, 2019 07:20:45 AM 10 November, 2019 7:20:45 10 November, 2019 07:20:45 11/10/2019 7:20 AM 11/10/2019 07:20 AM 11/10/2019 7:20 11/10/2019 07:20 11/10/19 7:20 AM 11/10/19 07:20 AM 11/10/19 7:20 11/10/19 07:20 11/10/19 7:20 AM 11/10/19 07:20 AM 11/10/19 7:20 11/10/19 07:20 11/10/2019 7:20 AM 11/10/2019 07:20 AM 11/10/2019 7:20 11/10/2019 07:20 19/11/10 7:20 AM 19/11/10 07:20 AM 19/11/10 7:20 19/11/10 07:20 2019-11-10 7:20 AM 2019-11-10 07:20 AM 2019-11-10 7:20 2019-11-10 07:20 10-Nov-19 7:20 AM 10-Nov-19 07:20 AM 10-Nov-19 7:20 10-Nov-19 07:20 11/10/2019 7:20:45 AM 11/10/2019 07:20:45 AM 11/10/2019 7:20:45 11/10/2019 07:20:45 11/10/19 7:20:45 AM 11/10/19 07:20:45 AM 11/10/19 7:20:45 11/10/19 07:20:45 11/10/19 7:20:45 AM 11/10/19 07:20:45 AM 11/10/19 7:20:45 11/10/19 07:20:45 11/10/2019 7:20:45 AM 11/10/2019 07:20:45 AM 11/10/2019 7:20:45 11/10/2019 07:20:45 19/11/10 7:20:45 AM 19/11/10 07:20:45 AM 19/11/10 7:20:45 19/11/10 07:20:45 2019-11-10 7:20:45 AM 2019-11-10 07:20:45 AM 2019-11-10 7:20:45 2019-11-10 07:20:45 10-Nov-19 7:20:45 AM 10-Nov-19 07:20:45 AM 10-Nov-19 7:20:45 10-Nov-19 07:20:45 November 10 November 10 2019-11-10T07:20:45.0000000 2019-11-10T07:20:45.0000000 Sun, 10 Nov 2019 07:20:45 GMT Sun, 10 Nov 2019 07:20:45 GMT 2019-11-10T07:20:45 7:20 AM 07:20 AM 7:20 07:20 7:20:45 AM 07:20:45 AM 7:20:45 07:20:45 2019-11-10 07:20:45Z Sunday, November 10, 2019 7:20:45 AM Sunday, November 10, 2019 07:20:45 AM Sunday, November 10, 2019 7:20:45 Sunday, November 10, 2019 07:20:45 November 10, 2019 7:20:45 AM November 10, 2019 07:20:45 AM November 10, 2019 7:20:45 November 10, 2019 07:20:45 Sunday, 10 November, 2019 7:20:45 AM Sunday, 10 November, 2019 07:20:45 AM Sunday, 10 November, 2019 7:20:45 Sunday, 10 November, 2019 07:20:45 10 November, 2019 7:20:45 AM 10 November, 2019 07:20:45 AM 10 November, 2019 7:20:45 10 November, 2019 07:20:45 November 2019 November 2019
示例
现在我们再来看一个实现 DateTime.GetDateTimeFormats() 方法的示例。对于 char 格式，我们使用诸如“d”（短日期模式）、“D”（长日期模式）、“F”（全日期/时间模式（长时间））等的格式说明符，
using System;
public class Demo {
public static void Main() {
DateTime d = new DateTime(2019, 11, 10, 7, 20, 45);
string[] res = d.GetDateTimeFormats('F');
foreach(string s in res)
Console.WriteLine(s);
}
}输出
这将生成以下输出 −
Sunday, November 10, 2019 7:20:45 AM Sunday, November 10, 2019 07:20:45 AM Sunday, November 10, 2019 7:20:45 Sunday, November 10, 2019 07:20:45 November 10, 2019 7:20:45 AM November 10, 2019 07:20:45 AM November 10, 2019 7:20:45 November 10, 2019 07:20:45 Sunday, 10 November, 2019 7:20:45 AM Sunday, 10 November, 2019 07:20:45 AM Sunday, 10 November, 2019 7:20:45 Sunday, 10 November, 2019 07:20:45 10 November, 2019 7:20:45 AM 10 November, 2019 07:20:45 AM 10 November, 2019 7:20:45 10 November, 2019 07:20:45
