Examples

The following code example displays the titles of items in a Tasks list where the Status column equals Completed. The example uses Collaborative Application Markup Language (CAML) to define the query.

This example requires using directives (Imports in Microsoft Visual Basic) for the [Microsoft.SharePoint] and [Microsoft.SharePoint.Utilities] namespaces.

Dim webSite As SPWeb = SPContext.Current.Site.RootWeb
Try
    Dim list As SPList = webSite.Lists("Tasks")

    Dim query As New SPQuery()
    query.Query = "<Where><Eq><FieldRef Name='Status'/>" + _
      "<Value Type='Text'>Completed</Value></Eq></Where>"
    Dim items As SPListItemCollection = list.GetItems(query)

    Dim item As SPListItem
    For Each item In  items
        Response.Write((SPEncode.HtmlEncode(item("Title").ToString()) + _
          "<BR>"))
    Next item
Finally
    webSite.Dispose()
End Try

using (SPWeb oWebsiteRoot = SPContext.Current.Site.RootWeb)
{

    SPList oList = oWebsiteRoot.Lists["Tasks"];

    SPQuery oQuery = new SPQuery();
    oQuery.Query = "<Where><Eq><FieldRef Name='Status'/>" +
        "<Value Type='Text'>Completed</Value></Eq></Where>";
    SPListItemCollection collListItems = oList.GetItems(oQuery);

    foreach (SPListItem oListItem in collListItems)
    {
        Response.Write(SPEncode.HtmlEncode(oListItem["Title"].ToString()) + 
            "<BR>");
    }
}
