SharePoint gets the value of the lookup field

It is common to get the value of the lookup field in a list, so we wrap it up

To get the lookup field value:

1         /// <summary>2         ///To get lookup field Id or Value3         /// </summary>4         /// <typeparam name= "T" ></typeparam>5         /// <param name= "item" ></param>6         /// <param name= "FieldName" ></param>7         /// <param name= "DefaultValue" ></param>8         /// <param name= "Getvaluetype" >0:return Id, 1:return Value</param>9         /// <returns></returns>Ten          Public StaticT getlookupfield<t> ( ThisSPListItem Item,stringFieldName,intGetvaluetype, T DefaultValue) One         { AFieldName = Fieldname.replace (" ", Constvariables.blankspicalcode); -  -             if(Item[fieldname] = =NULL) the             { -                 returnDefaultValue; -             } -  +             varitemelements = Regex.Split (Item[fieldname]. ToString (),";#", regexoptions.ignorecase); -  +             if(Itemelements.length >=2) A             { at                 returnConvertto<t>(Itemelements[getvaluetype], defaultvalue); -             } -             Else -             { -                 returnDefaultValue; -             } in}

Call this method: <oldplan is splistitem>
1. Get the ID of the lookup:

oldplan.getlookupfield<int> (Constvariables.Prcolumns. Columnstatus, 0, 0);
