'用途
Dim instance As SPTimeZone

  Type: System.DateTime

傳回值

Type: System.DateTime
包含日期和時間的System.DateTime結構轉換為其本機的值。

Examples

下列程式碼範例會顯示在文件庫所建立的共用文件和上次修改日期和時間值轉換為當地時間的每個檔案的日期和時間。

Dim siteCollection As New SPSite("https://localhost")
Dim site As SPWeb = siteCollection.AllWebs("Site_Name")
Dim files As SPFileCollection = site.Folders("Shared Documents").Files

Dim regionalSettings As SPRegionalSettings = site.RegionalSettings
Dim timeZone As SPTimeZone = regionalSettings.TimeZone

Dim file As SPFile

For Each file In  files

    Console.WriteLine(SPEncode.HtmlEncode(file.Title) _
        & " :: " & timeZone.UTCToLocalTime(file.TimeCreated) & " :: " _
        & timeZone.UTCToLocalTime(file.TimeLastModified) & "<BR>")

Next file

using (SPSite oSiteCollection = new SPSite("https://localhost"))
{
    using (SPWeb oWebsite = oSiteCollection.AllWebs["Website_Name"])
    {
        SPFileCollection collFiles = oWebsite.Folders["Shared Documents"].Files;
        SPRegionalSettings oRegionalSettings = oWebsite.RegionalSettings;
        SPTimeZone oTimeZone = oRegionalSettings.TimeZone;

        foreach (SPFile oFile in collFiles)
        {
            Console.WriteLine(oFile.Title +
            " :: " + oTimeZone.UTCToLocalTime(oFile.TimeCreated) +
            " :: " + oTimeZone.UTCToLocalTime(oFile.TimeLastModified) +
            "<BR>");
        }
    }
}
