TimeSpan格式化字符串格式(摘)

一直在用DateTime, 却不常用TimeSpan , 今天突然用到了, 发现不知道咋做格式化…百度一下,找到了答案, 在这记录一下, 免得以后找花费时间

以下内容摘抄自 Microsoft Docs  原文地址: https://docs.microsoft.com/en-us/previous-versions/windows/silverlight/dotnet-windows-silverlight/ee372287(v=vs.95)

分别展示了ToString方法跟string.Format方法中的方法, 其中string.Format的用法可以在mvc的Html.TextBox的format参数中使用

这里只记录下基本用法, 更多使用参考请移步上方链接.

TimeSpan转字符串

using System;

public class Example
{
   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
   {
      TimeSpan duration = new TimeSpan(1, 12, 23, 62);

      string output = null;
      output = "Time of Travel: " + duration.ToString("%d") + " days";
      outputBlock.Text += output + Environment.NewLine;
      output = "Time of Travel: " + duration.ToString(@"dd\.hh\:mm\:ss"); 
      outputBlock.Text += output + Environment.NewLine;

      outputBlock.Text += String.Format("Time of Travel: {0:%d} day(s)", 
                                        duration) + Environment.NewLine;
      outputBlock.Text += String.Format("Time of Travel: {0:dd\\.hh\\:mm\\:ss} days", 
                                        duration) + Environment.NewLine;
   }
}
// The example displays the following output:
//       Time of Travel: 1 days
//       Time of Travel: 01.12:24:02
//       Time of Travel: 1 day(s)
//       Time of Travel: 01.12:24:02 days

 

字符串转TimeSpan

using System;

public class Example
{
   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
   {
      string value = null;
      TimeSpan interval;

      value = "6";
      if (TimeSpan.TryParseExact(value, "%d", null, out interval))
         outputBlock.Text += String.Format("{0} --> {1}", value, 
                                           interval.ToString("c")) + Environment.NewLine;
      else
         outputBlock.Text += String.Format("Unable to parse '{0}'", value) + Environment.NewLine;

      value = "16:32.05";
      if (TimeSpan.TryParseExact(value, @"mm\:ss\.ff", null, out interval))
         outputBlock.Text += String.Format("{0} --> {1}", value, 
                                           interval.ToString("c")) + Environment.NewLine;
      else
         outputBlock.Text += String.Format("Unable to parse '{0}'", value) + Environment.NewLine;

      value= "12.035";
      if (TimeSpan.TryParseExact(value, "ss\\.fff", null, out interval))
         outputBlock.Text += String.Format("{0} --> {1}", value, 
                                           interval.ToString("c")) + Environment.NewLine;
      else
         outputBlock.Text += String.Format("Unable to parse '{0}'", value) + Environment.NewLine;
   }
}
// The example displays the following output:
//       6 --> 6.00:00:00
//       16:32.05 --> 00:16:32.0500000
//       12.035 --> 00:00:12.0350000
