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

Syntax

Public Property ViewFields As String
    Get
    Set

Dim instance As SPQuery
Dim value As String

value = instance.ViewFields

instance.ViewFields = value
public string ViewFields { get; set; }

Property Value

Type: System.String
A string that contains a fragment in Collaborative Application Markup Language that specifies the view fields.

Remarks

The ViewFields property allows you to specify which fields to return in a query on a list.

The ViewFields property contains a string that corresponds to the inner XML of the ViewFields element in CAML.

Examples

The following code example uses the ViewFields property to specify two fields to return in a 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.AllWebs("Site_Name")
Try
     Dim list As SPList = webSite.Lists("List_Name")

    Dim query As New SPQuery()
    query.ViewFields = "<FieldRef Name='Field1'/>" + _
        "<FieldRef Name='Field2'/>"
    Dim items As SPListItemCollection = list.GetItems(query)

    Dim item As SPListItem
    For Each item In  items
        Response.Write((SPEncode.HtmlEncode(item.Xml) + "<BR>"))
    Next item
Finally
    webSite.Dispose()
End Try 
using (SPWeb oWebsite = SPContext.Current.Site.AllWebs["Site_Name"])
{
    SPList oList = oWebsite.Lists["List_Name"];

    SPQuery oQuery = new SPQuery();
    oQuery.ViewFields = "<FieldRef Name='Field1'/>" +
        "<FieldRef Name='Field2'/>";
    SPListItemCollection colListItemsAvailable = 
      oList.GetItems(oQuery);

    foreach (SPListItem oListItemAvailable in colListItemsAvailable)
    {
        Response.Write(SPEncode.HtmlEncode(oListItemAvailable.Xml) + 
          "<BR>");
    }
}

Note

Certain objects implement the IDisposable interface, and you must avoid retaining these objects in memory after they are no longer needed. For information about good coding practices, see Best Practices: Using Disposable Windows SharePoint Services Objects.
