c# fundamentals

Question

why we are not using pointer in c#?

what is reflection in .net?

can we call a function under another function? 

Answer 1

As you are fetching values under a loop that runs arNama.length, you can also initialize your variable with the fixed array size

var markers = new int [arNama.Length];

 

Or you can create dynamic creation of arrays as manas has pointed out

Answer 2

hi mr. Manas and mr. Amit thanks for reply my question. I try to use code's mr. Amit but code result always the last value not all value. let see my script on java script :

 

var strNama = document.getElementById('<%=keyidnama.ClientID %>').value;
var strBusur= document.getElementById('<%=keyBusur.ClientID %>').value;
var strLintang= document.getElementById('<%=keyLintang.ClientID %>').value;
var strAlamat= document.getElementById('<%=keyAlamat.ClientID %>').value;
var arNama = strNama.split('~');
var arBusur= strBusur.split('~');
var arLintang= strLintang.split('~');
var arAlamat=strAlamat.split('~');
var markers = [arNama.length];
for(var i = 0; i < arNama.length; i++) {
markers = [
[i, arNama[i], arLintang[i], arBusur[i], arAlamat[i]],

];
}

 

oh, mr. manas thanks for your code, I used to in my code behind it's work

If you want array needs to be variable length then you need to use ArrayList or List.See below code: 

ArrayList list = new ArrayList();
list.Add(1);
list.Add(2);
list.Add(3);

foreach (int i in list)
{
    Console.WriteLine(i);
}
