hi,

i using below c# code storing record in arraylist.

i want code handle following:
if record coming first time should add directly, if record existing in list should increment appearancecount.

the output of below code is:
330, 450, 2
330, 589, 1

since '330,450' values came twice incremented , appearancecount i.e third field set 2.

please me code this.

thanks.

like have encountered in previous posts view today, arraylist deprecated i.e. used better ways utilize have been created , suggested use them.

for arraylist, list<objecttype>.

now coming to your program:

static void main(string[] args){

mydatastructure myds = new mydatastructure();

myds.add(330,450);

myds.add(330,589);

myds.add(330,450);

console.readline();

} //end of main

class mydatastructure{

list<twopathinfo> tpilist;

public mydatastructure(){

tpilist = new list<twopathinfo>();

}

public void add(int param1, int param2){

foreach(twopathinfo tpiloopvar in tpilist){

if(tpiloopvar.path1 == param1 && tpiloopvar.path2 == param2){

tpiloopvar.appearancecount++;

break;

}//end of if

}//end of foreach

}//end of add method

}//end of class

 

hope solves problem
