i'm new c# programming. trying create new objects (in case studentinfo object) , place them in array studentarr.
the array initialized length = 5 , want create 5 studentinfo objects , add them array. don't think it's doing @ , don't know i'm going wrong.
i'm supposed enter student information through console.readline 5 different students , it's printing out first student information.
i'm using struct access student info.
some appreciated!
static void main(string[] args) { studentinfo[] studentarr = new studentinfo[5]; int objectnumber = 0; (int = 0; < studentarr.length; i++) { studentarr[i] = new studentinfo(); console.writeline("please enter studentid, studentname, coursename, date-of-birth"); studentarr[i].firstname = console.readline(); studentarr[i].lastname = console.readline(); studentarr[i].birthday = console.readline(); studentarr[i].studentid = console.readline(); studentarr[i].addressline1 = console.readline(); studentarr[i].addressline2 = console.readline(); studentarr[i].city = console.readline(); studentarr[i].state = console.readline(); studentarr[i].zipcode = console.readline(); studentarr[i].country = console.readline(); objectnumber = + 1; } (int = 0; < studentarr.length; i++) { console.writeline( "{0} {1} born on {2}. student id: {3}", studentarr[0].firstname, studentarr[0].lastname, studentarr[0].birthday, studentarr[0].studentid); console.writeline( "address: {0} {1} \n\t {2} {3} {4} {5}.", studentarr[0].addressline1, studentarr[0].addressline2, studentarr[0].city, studentarr[0].state, studentarr[0].zipcode, studentarr[0].country); } } public struct studentinfo { public string firstname; public string lastname; public string birthday; public string studentid; public string addressline1; public string addressline2; public string city; public string state; public string zipcode; public string country; // constructor studentinfo public studentinfo( string first, string last, string dob, string id, string address1, string address2, string city, string state, string zip, string country) { this.firstname = first; this.lastname = last; this.birthday = dob; this.studentid = id; this.addressline1 = address1; this.addressline2 = address2; this.city = city; this.state = state; this.zipcode = zip; this.country = country; } }
you printing first element @ 0 writing studentarr[0]. should studentarr[i]
for (int = 0; < studentarr.length; i++) { console.writeline("{0} {1} born on {2}. student id: {3}", studentarr[i].firstname, studentarr[i].lastname, studentarr[i].birthday, studentarr[i].studentid); console.writeline("address: {0} {1} \n\t {2} {3} {4} {5}.", studentarr[i].addressline1, studentarr[i].addressline2, studentarr[i].city, studentarr[i].state, studentarr[i].zipcode, studentarr[i].country); }
