Please guide me

Try this - I haven' tested it yet though.

public static void Repath(Database db, string xrefName, string newPath)
            {
            if (string.IsNullOrEmpty(newPath))
                {
                throw new Autodesk.AutoCAD.Runtime.Exception(ErrorStatus.FileNotFound, "The path can not be found");
                }

            if (!File.Exists(newPath))
                {
                throw new Autodesk.AutoCAD.Runtime.Exception(ErrorStatus.FileNotFound, "The file can not be found");
                }

            BlockTableRecord btr = default(BlockTableRecord);
            using (Transaction tr = db.TransactionManager.StartTransaction())
                {
                XrefGraph DbXrGraph = db.GetHostDwgXrefGraph(true);
                XrefGraphNode XrGraphNode = null;

                XrGraphNode = DbXrGraph.GetXrefNode(xrefName);
                btr = (BlockTableRecord)tr.GetObject(XrGraphNode.BlockTableRecordId, OpenMode.ForWrite);
                btr.PathName = newPath;
                tr.Commit();
                }
            }
