Lập trình web nâng cao XML - Trường CĐN Đà Lạt - 24

public int id;

public String firstName; public String lastName; public String email; public String phone; public String username; public String password; public Address address;

Golfer cũng có vài phương thức kiến tạo: public Golfer()

{

id = 0; firstName = ""; lastName = ""; email = "";

phone = ""; username = ""; password = "";

address = new Address();

}

public Golfer(String _firstName, String _lastName, String _email, String _phone, String _streetAddress, String _city, String _state, String _postalCode, String _country, String _username, String _password)

{

firstName = _firstName; lastName = _lastName; email = _email;

phone = _phone; username = _username; password = _password; address = new Address();

address.setStreet(_streetAddress); address.setCity(_city); address.setState(_state); address.setPostalCode(_postalCode); address.setCountry(_country);

}

public Golfer(courseDataSet ds, int golferId)

{

id = 0; firstName = ""; lastName = ""; email = "";

phone = ""; username = ""; password = "";

address = new Address();

courseDataSet.golfersRow g = ds.golfers.FindByid(golferId); if (g != null)

{

id = golferId;

if (!g.IsfirstNameNull()) firstName = g.firstName; if (!g.IslastNameNull()) lastName = g.lastName; if (!g.IsemailNull())

email = g.email;

if (!g.IsphoneNull()) phone = g.phone;

if (!g.IsusernameNull()) username = g.username; if (!g.IspasswordNull()) password = g.password;

if (!g.IsstreetAddressNull()) address.setStreet(g.streetAddress); if (!g.IscityNull()) address.setCity(g.city);

if (!g.IsstateNull()) address.setState(g.state); if (!g.IspostalCodeNull())

address.setPostalCode(g.postalCode); if (!g.IscountryNull()) address.setCountry(g.country);

}

}

filterString += " AND";

}

filterString += " "+fields[x]+" LIKE '"+values[x]+"'";

}

cv.RowFilter = filterString; int nCourses = cv.Count;

GolfCourse[] golfCourses = new GolfCourse[nCourses]; int cnt = 0;

foreach (DataRowView c in cv)

public GolfCourse AddTee(int courseId, String description, float slope)

{

courseDataSet.teeRow newTee = courseDataSet1.tee.AddteeRow(courseId,description,0,slope);

teeDataAdapter.Update(courseDataSet1,"tee"); courseDataSet1.AcceptChanges();

GolfCourse gc = new GolfCourse(courseDataSet1, courseId); return gc;

}

AddHole( )

[WebMethod]

public GolfCourse AddHole(int teeId, int handicap, int length, int hole, int par)

{

courseDataSet.HoleRow newHole = courseDataSet1.Hole.AddHoleRow (handicap,length,teeId,hole,par); holeDataAdapter.Update(courseDataSet1,"Hole"); courseDataSet1.AcceptChanges();

courseDataSet.teeRow tr = courseDataSet1.tee.FindByid(teeId); int courseId = tr.courseId;

GolfCourse gc = new GolfCourse(courseDataSet1, courseId); return gc;

}

AddTeeTime( )

cú pháp: TeeTime AddTeeTime(int courseId, int golfer, DateTime date, DateTime time) Tạo một bảng ghi tee time mới:
