关于sharepoint 的如何动态写Meta部分的内容

我想应该用不同的方法,我想以下应该是其中一种

My approach would be to create a special render control and generate the required HTML code via the control.

1) Create a render control and override the RenderFieldForDisplay method. For an example, see http://msdn2.microsoft.com/en-us/library/aa981226.aspx. This article shows also how to create the custom edit mode but you don't need all of it.

Deploy the custom control as mentioned in the article.

2) Add the contentplaceholder in the master page (as you already tried), or use the default <asp:ContentPlaceHolder id="PlaceHolderAdditionalPageHead" runat="server"/>

Place this in the <head> section, right after the <title> tag for example.

3) Call the custom control to render the meta description field in the page layout:

<asp:Content ContentPlaceholderID="PlaceHolderAdditionalPageHead" runat="server">

<PublishingWebControls:EditModePanel runat="server" id="displayModeMetadata" PageDisplayMode="Display" SuppressTag="true">

<Mytag:HeadMetadataFieldControl FieldName="MyMetadatafieldname" runat="server"></Mytag:HeadMetadataFieldControl>

</PublishingWebControls:EditModePanel>

</asp:Content>

Hope this is clear enough.

using Microsoft.SharePoint;

using System.Data;

namespace MyControls

{

public class KeywordsTag: UserControl

{

public override void RenderControl(HtmlTextWriter writer)

{

//Get the sp file context and retrieve corresponding field

try

{

SPFile file = SPContext.Current.File;

String keywords = file.Item["Keywords"].ToString();

//read the keywords field and render

writer.Write("<meta name=\"keywords\" content=\"" + keywords + "\" />");

}

catch { }

base.RenderControl(writer);

}

}

}

Build your user control library and add a Tag prefix in your master page.

<%@ Register Tagprefix="MyTag" Namespace="MyControls" Assembly="AssemblyName, Version=1.0.0.0, Culture=neutral, PublicKeyToken=1b25d240d1396f63" %>

Note: The Assembly Name , Version, Culture and PublicToken have to be changed to your Assembly Name , Version, Culture and PublicToken

On your master page add the control before the title tag as below:

<MyTag:KeywordsTag runat="server" />

Your pages derived from the modified master page will show the meta keywords tag.

This assumes that you are using the Field Named "Keywords" to store your keywords. If you are using a field like "mykeywords" change your user control accordingly.
