Examples
The following code example displays the internal names of fields that involve field references.
The example assumes the existence of an .aspx page that contains a label control.
This example requires using directives (Imports in Visual Basic) for the Microsoft.SharePoint and Microsoft.SharePoint.Utilities namespaces.
Dim site As SPSite = SPContext.Current.Site
Dim web As SPWeb = site.AllWebs("Site_Name")
Dim fields As SPFieldCollection = web.Lists("List_Name").Fields
Dim i As Integer
For i = 0 To fields.Count - 1
Dim refFields As String() = fields(i).FieldReferences
If Not (refFields Is Nothing) Then
Dim j As Integer
For j = 0 To refFields.Length - 1
Label1.Text += SPEncode.HtmlEncode(refFields(j)) & "<BR>"
Next j
End If
Next i
SPSite oSiteCollection = SPContext.Current.Site;
SPWeb oWebsite = oSiteCollection.AllWebs["Site_Name"];
SPFieldCollection collFields = oWebsite.Lists["List_Name "].Fields;
for (int intIndex=0; intIndex<collFields.Count; intIndex++)
{
string[] strRefFields = collFields[intIndex].FieldReferences;
if (strRefFields != null)
{
for (int intStrPos=0; intStrPos<strRefFields.Length; intStrPos++)
{
Label1.Text += SPEncode.HtmlEncode(strRefFields[intStrPos]) + "<BR>";
}
}
}
oWebsite.Dispose();
