範例

下列範例會將指定的 DateTime 轉換為 DMTF 日期時間格式。

using System;
using System.Management;

// The sample below demonstrates the various conversions
// that can be done using ManagementDateTimeConverter class
class Sample_ManagementDateTimeConverterClass

        // Converting DMTF time interval to System.TimeSpan
        System.TimeSpan tsRet =

備註

產生的 DMTF 日期時間字串是以目前時區的 UTC 位移為基礎。 DMTF 中最低的有效位數是微秒;在 中 DateTime，最低有效位數為 Ticks，相當於100奈秒。 在轉換期間， Ticks 會轉換成微秒，並將四捨五入為最接近的微秒。
