How to: Create or Delete a Site or a Site Collection

Applies to: SharePoint Foundation 2010

Available in SharePoint Online

To create a site, use one of the Add() methods of the SPWebCollection class. To create a subsite beneath a site, use the Webs property of the SPWeb class to return the collection of subsites and then call one of the Add() methods for the collection.


The code examples in this topic use members of the Microsoft.SharePoint.SPContext class to obtain the current site collection, Web site, or list. Outside of an HTTP context, such as in a console application or a Windows application, you obtain references to key objects by using a different method. For more information, see Getting References to Sites, Web Applications, and Other Key Objects.

The following example creates a new subsite that is based on the template of the current site and on information gathered from three text boxes. The text boxes specify the name to use in the new URL, the title to use for the site, and a description for the site.

In the example, the WebTemplate property of the SPWeb class returns the name of the current site definition, which is passed as a parameter of the Add method. In addition, three parameters for this method pass the information that is gathered from the three text boxes. The three other parameters specify the following:

  • LocaleID folder (where LocaleID is the locale identifier (LCID) for the installation; the LCID for English - United States is 1033)

  • true to create a site with unique permissions, and

  • false to convert any existing Web site at the same location to a SharePoint site.

Dim mySite As SPWeb = SPContext.Current.Web
Dim subSites As SPWebCollection = mySite.Webs
Dim currentTemplate As String = mySite.WebTemplate

Dim siteUrl As String = TextBox1.Text.ToString()
Dim siteTitle As String = TextBox2.Text.ToString()
Dim siteDescription As String = TextBox3.Text.ToString()

subSites.Add(siteUrl, siteTitle, siteDescription, 
   Convert.ToUInt32(1033), currentTemplate, True, False)
SPWeb mySite = SPContext.Current.Web;
SPWebCollection subSites = mySite.Webs;
string currentTemplate = mySite.WebTemplate;

string siteUrl = TextBox1.Text.ToString();
string siteTitle = TextBox2.Text.ToString();
string siteDescription = TextBox3.Text.ToString();

subSites.Add(siteUrl, siteTitle, siteDescription, 1033, 
   currentTemplate, true, false); 

To delete a site, use the Delete method of the SPWeb class or the Delete method of the SPWebCollection class.

The following example assumes the use of a text box to specify the URL of a site to delete, and uses the Delete method of the SPWebCollection class to delete the site.

Dim deleteSite As String = TextBox1.Text.ToString()

Dim mySite As SPSite = SPContext.Current.Site
Dim sites As SPWebCollection = mySite.AllWebs

string deleteSite = TextBox1.Text.ToString();

SPSite mySite = SPContext.Current.Site;
SPWebCollection sites = mySite.AllWebs;


In the example, the AllWebs property of the SPSite class returns the collection of all sites within the current site collection.

The previous examples each require a using directive (Imports in Visual Basic) for the Microsoft.SharePoint namespace.
