SPWebService class

Represents a Web service that contains one or more Web applications. This Web service allows a Web browser to access the content in SharePoint sites.

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

The SPWebService class is primarily a container for SPWebApplication objects. Use the WebService property of the SPWebApplication class to return the parent Web service of a Web application. To return a reference to the current Web service, you can use SPWebService.ContentService.

To return the collection of Web services that are installed in the farm, use the SPWebServiceCollection constructor.

In general, you can get an SPWebService object from the ContentService property. You can also use an indexer to return a single Web service from the collection. For example, if the collection is assigned to a variable named myWebServices, use myWebServices[index] in C#, or myWebServices(index) in Visual Basic, where index is either the name or the GUID that identifies the Web service.

The following example iterates through all of the Web services in a server farm and changes the maximum site count and warning site count of all the content databases that are used for each Web application.

SPWebServiceCollection webServices = new SPWebServiceCollection(SPFarm.Local);

foreach (SPWebService webService in webServices)

    foreach (SPWebApplication webApp in webService.WebApplications)

        if (!webApp.IsAdministrationWebApplication)
            SPContentDatabaseCollection contentDatabases = webApp.ContentDatabases;

            foreach (SPContentDatabase database in contentDatabases)
                database.WarningSiteCount = 4900;
                database.MaximumSiteCount = 5000;
