问题描述

我有一个返回日期时间字段的Web服务.

我得到一个结果/Date(1379048144000)/但

我只想1379048144000我怎么能做到这一点.

[WebMethod]
public DateTime GetServerDate()
{
    return DateTime.Now;
}

通过设置Header Content-Type:application/json; charset = utf-8;我得到了类似/Date(1379048144000)/的结果.

by setting Header Content-Type: application/json; charset=utf-8; i got a result like /Date(1379048144000)/.

推荐答案

您可以更改WS以返回带有DateTime值的long.返回的值是自Unix纪元(01/01/1970)以来的毫秒数.这可以通过DateTime上的扩展方法来完成，例如:

You could change your WS to return a long with the value of the DateTime. The value to return is the number of milliseconds since the Unix Epoch (01/01/1970). This could be done with an extension method on DateTime something like:

public static class DateTimeExtensions
{
    ...
    private static readonly DateTime UnixEpoch = new DateTime(1970, 1, 1);

    public static long ToUnixTime(this DateTime dateTime)
    {
        return (dateTime - UnixEpoch).Ticks / TimeSpan.TicksPerMillisecond;
    }
    ...
}

您的Web服务方法可能类似于:

And your web service method might look something like:

public long GetMyDate(...)
{
    DateTime dateTime = ...;
    return dateTime.ToUnixTime();
}
