SPFile.Properties 属性

获取元数据的文件。

命名空间：  Microsoft.SharePoint
程序集：  Microsoft.SharePoint（位于 Microsoft.SharePoint.dll 中）

语法

声明
Public ReadOnly Property Properties As Hashtable
    Get
用法
Dim instance As SPFile
Dim value As Hashtable

value = instance.Properties

public Hashtable Properties { get; }

属性值

类型：System.Collections.Hashtable
System.Collections.Hashtable对象，该对象包含的元数据。

备注

Windows SharePoint Services 3.0对象模型支持更新文件元数据。可以在此属性上使用索引器设置值。例如，若要将一个给定文件的MyDate属性的值设置为当前日期和时间，使用索引和，如下所示调用Update方法：

[Visual Basic]

oFile("MyDate") = DateTime.Now

oFile.Update()

[C#]

oFile["MyDate"] = DateTime.Now;

oFile.Update();

示例

下面的代码示例循环访问文档库中的文件的集合，并显示的属性和值的每个文件。

此示例要求using指令 （在 Visual Basic 中的Imports ） 的Microsoft.SharePoint和Microsoft.SharePoint.Utilities的命名空间。

Dim siteCollection As SPSite = SPContext.Current.Site
Dim site As SPWeb = siteCollection.AllWebs("Site_Name")

Dim folder As SPFolder = site.Folders("Shared Documents")
Dim files As SPFileCollection = folder.Files
Dim file As SPFile

For Each file In  files

    Dim hash As System.Collections.Hashtable = file.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 file

SPSite oSiteCollection = SPContext.Current.Site;
using(SPWeb oWebsite = oSiteCollection.AllWebs["Site_Name"])
{
    SPFolder oFolder = oWebsite.Folders["Shared Documents"];
    SPFileCollection collFiles = folder.Files;

    foreach (SPFile oFile in collFiles)
    {
        System.Collections.Hashtable collHashes = file.Properties;
        System.Collections.ICollection collKeys = hash.Keys;

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

前面的示例中显示类似于以下元数据：

vti_author :: User_Name
vti_cachedtitle :: New Page 1
vti_metatags :: HTTP-EQUIV=Content-Language en-us GENERATOR Microsoft\ 
    FrontPage\ 5.0 ProgId FrontPage.Editor.Document
