如何在asp.net mvc的网格中更改日期时间格式

Question

I want to change my date time format from 7/20/2016 10:30:00 AM to 20 July 2016 10:30 AM

Bellow is the image in where i want to change the format

Bellow is my code in controller where i have a events data table and in there columns i have added the event name , occurrence time and recovery time

DataTable events = new DataTable();
        events.Columns.Add("Event_Name", typeof(string));
        events.Columns.Add("Occurrence_Time", typeof(string));
        events.Columns.Add("Recovery_Time", typeof(string));


                while (reader_events.Read())
                {

                    events.Rows.Add(Convert.ToString(reader_events["Event_Name"]), 
                    Convert.ToString(reader_events["Occurrence_Time"]).ToString(),
                    Convert.ToString(reader_events["Recovery_Time"]));           


                 }

After that i have passed these events in view data ViewData["events"] = events;

Bellow is my razor syntax

if (ViewData["events"] != null)
{
  if (ViewData.Values != null && ViewData.Values.Count() > 0)
  {
     foreach (System.Data.DataRow dr in (ViewData["events"] as System.Data.DataTable).Rows)
     {
        <tr>
           <td style="border:1px solid black; color:green;font-family:'Segoe UI', Tahoma, Geneva, Verdana, sans-serif">
              @dr[0]

            </td>
            <td style="border:1px solid black; color:green;font-family:'Segoe UI', Tahoma, Geneva, Verdana, sans-serif">
               @dr[1]
            </td>
            <td style="border:1px solid black; color:green;font-family:'Segoe UI', Tahoma, Geneva, Verdana, sans-serif">
              @dr[2]
            </td>
       </tr>
       }
      }
    }

Any help would be highly appreciated

Answer 1

you can use the following

@(string.Format("{0:dd MMMM yyyy hh:mm tt}",dr[1]))

in case dr[1] was string, you need to parse it as datetime then apply formatting like this:

@(string.Format("{0:dd MMMM yyyy hh:mm tt}",DateTime.Parse(dr[1])))

please note that the parse in order to work perfectly you need to have some culture validation

another solution, is to setup the datetime from the controller it self by using typeof(DateTime) instead of typeof(string)

for example:

1. apply the changes in the data table declaration:

events.Columns.Add("Occurrence_Time", typeof(DateTime));

2. apply the changes in the retrieving part

Convert.ToDateTime(reader_events["Occurrence_Time"]),

3. You can use the string.Format from the view side

Hope this will help you

Answer 2

Use DateTime.ParseExact,

 e.g.: DateTime.ParseExact("12/02/21 10:56:09", "yy/MM/dd HH:mm:ss", 
    CultureInfo.InvariantCulture
    ).ToString("MMM. dd, yyyy HH:mm:ss")

Modify the code according to your need.

Answer 3

您可以使用 .ToString 完整日期和时间

 yourDate.ToString("dd MMMM yyyy hh:mm tt", CultureInfo.CreateSpecificCulture("en-US"));

Answer 4

在数据表中添加数据并检查期间，将Convert.ToString(reader_events["Recovery_Time"])更改为reader_events["Recovery_Time"].ToString("dd MMMM yyyy hh:mm tt") 。
