SPControl.GetContextSite method

  • 發行項

Returns the site collection that serves as context for the request.

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

Syntax

'Declaration
Public Shared Function GetContextSite ( _
    context As HttpContext _
) As SPSite
'Usage
Dim context As HttpContext
Dim returnValue As SPSite

returnValue = SPControl.GetContextSite(context)

public static SPSite GetContextSite(
    HttpContext context
)

Parameters

  • context
    Type: System.Web.HttpContext

    A System.Web.HTTPContext object, which encapsulates the HTTP-specific context that is used by the server to process site requests.

Return value

Type: Microsoft.SharePoint.SPSite
A Microsoft.SharePoint.SPSite object that represents the site collection.

Remarks

  • The GetContextSite method is used in code running within an HTTP context that is integrated with a Windows SharePoint Services deployment. The code can be used in a Web Part, in a custom Web service (in _vti_bin), or in an ASPX page or Web Application (in _layouts). In each of these cases, the solution is available to any SharePoint site on the front-end Web server, and the GetContextSite method returns the SPSite object for the current HTTP request. For example, a custom ASPX page (_layouts/1033/MyItems.aspx) that returns all list items created by the user accessing the page would be available for use in all sites on the Web server by browsing to URLs like the following:

  • http:// Server_Name /_layouts/1033/MyItems.aspx

  • http:// Server_Name /sites/ Site_Collection /_layouts/1033/MyItems.aspx

  • http:// Server_Name / Subsite /_layouts/1033/MyItems.aspx

Do not use the Dispose or Close method of the SPSite class to close the object returned through the GetContextSite method. Instead let SharePoint Foundation or your portal application manage the object.

For more information, see Getting References to Sites, Web Applications, and other Key Objects.

Examples

The following code example uses the GetContextSite method in conjunction with the GetContextWeb method to return both a site collection object and a site object on an .aspx page.

[Visual Basic .NET]
<% Dim siteCollection As SPSite = SPControl.GetContextSite(Context)
Dim site As SPWeb = SPControl.GetContextWeb(Context) %>
[C#]
<% SPSite siteCollection = SPControl.GetContextSite(Context); 
   SPWeb site = SPControl.GetContextWeb(Context); %>
