MapXtreme2005中如何将一个已经存在的表索引化成为一个本地的表？

003、如何将一个已经存在的表索引化成为一个本地的表？？？
ISession session = MapInfo.Engine.Session.Current;

Table tableToIndex = session.Catalog["DIJISHI"];
MapInfo.Data.TableInfoNative ti = (MapInfo.Data.TableInfoNative)MapInfo.Data.TableInfoFactory.CreateFromFeatureCollection("NewTable", 
      MapInfo.Data.TableType.Native, tableToIndex);
ti.Columns["PINYIN"].Indexed = true;
ti.TablePath = "C:\\NewTable.tab";
ti.WriteTabFile();

MapInfo.Data.Table nativetable = MapInfo.Engine.Session.Current.Catalog.CreateTable(ti);
nativetable.Close();
nativetable = MapInfo.Engine.Session.Current.Catalog.OpenTable("C:\\NewTable.tab");

MapInfo.Data.MIConnection con = new MapInfo.Data.MIConnection();
con.Open();
MapInfo.Data.MICommand com = con.CreateCommand();

com = con.CreateCommand();
com.CommandText = "Insert into " + nativetable.Alias + " Select * from " + tableToIndex.Alias;

com.Prepare();
com.ExecuteNonQuery();

com.Dispose();
con.Dispose();
con.Close();
注：也可以使用如下的函数来将上述代码进行封装：
private MapInfo.Data.Table CreateIndexedNativeTableFromExisting(
  MapInfo.Data.Table tableToIndex,
  string columnAliasToIndex,
  string AliasForNewTable,
  string FilePathToSaveNativeTable,
  bool CloseOldTable)
