Examples

The following code example iterates through the collection of fields for a list and displays the title and type of each field.

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

The example assumes the existence of an .aspx page that contains a label control.

Dim webSite As SPWeb = SPContext.Current.Site.AllWebs("MySite")
Try
    Dim fields As SPFieldCollection = webSite.Lists("MyList").Fields
    Dim i As Integer

    For i = 0 To fields.Count - 1
        Label1.Text += SPEncode.HtmlEncode(fields(i).Title) + " :: " + fields(i).TypeAsString + "<BR>"
    Next i
Finally
    webSite.Dispose()
End Try
using (SPWeb oWebsite = SPContext.Current.Site.AllWebs["MySite"])
{
    SPFieldCollection collFields = oWebsite.Lists["MyList"].Fields;

    for (int intIndex=0; intIndex<collFields.Count; intIndex++)
    {
        Label1.Text += SPEncode.HtmlEncode(collFields[intIndex].Title) + " :: " + collFields[intIndex].TypeAsString + "<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 Disposing Objects.
