mapxtreme2004經典代碼之二：TableInfo

The example code below convers the concept of System.Reflection.

Also it is a Window application, but I have write Console.WriteLine() method in it, so u should run it in the command line like this

eg: application.exe >info.txt

 1

         private   void  button2_Click( object  sender, System.EventArgs e)

 2

{

 3

            Table table = MapInfo.Engine.Session.Current.Catalog[this.mapControl1.Map.Layers[0].Alias];

 4

 5

            TableInfo ti = table.TableInfo;

 6

            Type type = ti.GetType();

 7

 8

            PropertyInfo[] api = type.GetProperties();

 9

            string s1="";

10

            foreach(PropertyInfo pi in api)

11

{

12

                s1 += pi.Name +"="+ pi.GetValue(ti,null)+"\r\n";

13

            }            

14

15

            Console.WriteLine(s1);

16

            Console.WriteLine();

17

18

            s1="";

19

            foreach(PropertyInfo pi in api)

20

{

21

                s1 += pi.Name +"="+ pi.GetValue(ti,null)+"\r\n";

22

            }

23

24

25

            s1+="\r\n";

26

27

            FieldInfo[] afi = type.GetFields();

28

            foreach(FieldInfo fi in afi)

29

{

30

                s1 += fi.Name+"="+fi.GetValue(ti);

31

            }

32

33

34

            s1 += "\r\n";

35

            foreach(Column c in ti.Columns)

36

{

37

38

                s1 += "Alias="+c.Alias+"\r\n"+"DataType="+c.DataType+"\r\n"+"Width="+c.Width+"\r\n";                

39

                if(c.DataType == MIDbType.FeatureGeometry)

40

{

41

                    GeometryColumn gc = (GeometryColumn)c;

42

                    MapInfo.Geometry.CoordSys cs = gc.CoordSys;

43

                    s1 += "MapBasicString="+cs.MapBasicString+"\r\n";

44

                    MapInfo.Geometry.DRect dr = gc.Bounds;

45

                    s1 += "Bounds="+dr+"\r\n";

46

                }

47

48

            }

49

50

            Console.WriteLine(s1);

51

52

        }
