Try
Dim fields As SPFieldCollection = webSite.Lists("MyList").Fields
Dim delField As String = fields("MyField").Title
fields.Delete(delField)
Finally
webSite.Dispose()
End Try
using (SPWeb oWebsite = SPContext.Current.Site.AllWebs["MySite"])
{
SPFieldCollection collFields = oWebsite.Lists["MyList"].Fields;
string strDelField = collFields["MyField"].Title;
collFields.Delete(strDelField);
}
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.
