Namespace:  Microsoft.SharePoint
Assembly:  Microsoft.SharePoint (in Microsoft.SharePoint.dll)

Syntax

'宣告
Public ReadOnly Property Properties As Hashtable
    Get
'用途
Dim instance As SPFileVersion
Dim value As Hashtable

value = instance.Properties

public Hashtable Properties { get; }

Property value

Type: System.Collections.Hashtable
System.Collections.Hashtable物件，包含中繼資料。

Examples

下列程式碼範例會逐一查看集合的指定檔案的版本，並顯示的屬性和每個版本的值。

這個範例要求using指示詞 (在 Visual Basic 的Imports ) 的Microsoft.SharePoint和Microsoft.SharePoint.Utilities命名空間。

Dim siteCollection As SPSite = SPControl.GetContextSite(Context)
Dim site As SPWeb = siteCollection.AllWebs("Site_Name")

Dim files As SPFileCollection = site.Folders("Shared Documents").Files
Dim fileVersions As SPFileVersionCollection = 
    files("File_Name").Versions
Dim fileVersion As SPFileVersion

For Each fileVersion In  fileVersions

    Dim hash As System.Collections.Hashtable = fileVersion.Properties
    Dim keys As System.Collections.ICollection = hash.Keys
    Dim key As Object

    For Each key In  keys

        Response.Write(SPEncode.HtmlEncode(key.ToString()) & " :: " & 
            SPEncode.HtmlEncode(hash(key.ToString()).ToString()) & 
            "<BR>")

    Next key

Next fileVersion

SPSite oSiteCollection = SPContext.Current.Site;
using (SPWeb oWebsite = oSiteCollection.AllWebs["Site_Name"])
{
    SPFileCollection collFiles = oWebsite.Folders["Shared Documents"].Files;
    SPFileVersionCollection collFileVersions = collFiles["File_Name"].Versions;

    foreach (SPFileVersion oFileVersion in collFileVersions)
    {
        System.Collections.Hashtable oHash = oFileVersion.Properties;
        System.Collections.ICollection collKeys = oHash.Keys;

        foreach (object oKey in collKeys)
        {
            Response.Write(SPEncode.HtmlEncode(oKey.ToString()) + 
            " :: " + SPEncode.HtmlEncode(oHash[oKey.ToString()].ToString()) + "<BR>");
        }
    }
}

前一個範例會顯示中繼資料，如下所示：

vti_sourcecontrolcookie :: fp_internal
vti_timelastmodified :: 5/6/2003 8:42:10 PM
vti_sourcecontrolversion :: V2
vti_cachedcustomprops :: vti_title
vti_hasdefaultcontent :: true
vti_cachedtitle :: File_Title
vti_title :: File_Title
vti_modifiedby :: User_Name
vti_oldversion :: 1
vti_filesize :: 19968
vti_author :: User_Name

注意事項
某些物件實作IDisposable介面，並且您必須避免之後不再需要保留這些物件在記憶體中。良好的程式碼撰寫方式的相關資訊，請參閱Disposing Objects。
