Hello,
I'm a very very newbie in C# I did start 2 days ago, I get Visual
Stuido 2005 C#
I try to understand how to manage the arrays
I did write this
int[] tempo=new int[3];
int[,] list = { { 1, 2, 3 } , { 11,12,13} };
int[] search = { 15, 123, 12 };
I have to goals here
My main goal is to find if values in array search exist in list[0]
and list[1]
My only idea, with my knowledge, is
- 1st to copy all the value of the multi-dimensional array list[1,] to
a tempo array
- to search in the temporary array, all the value of search, I
programmed the method contains for that.
To be frank I'm sure there is much simpler than this.
Thank you fro your help
namespace loto_Sharp
{
class Program
{
// Search value of array search in the temporary array tempo
private static bool contains(int[] tempo,int[] search)
{
Array.Sort(temp o);
Array.Sort(sear ch);
for (int bcl = 0; bcl < tempo.GetLength (0); bcl++)
{
System.Console. Write("Cherche {0}", search[bcl]);
if (Array.BinarySe arch(tempo, search[bcl]) >= 0)
{
System.Console. WriteLine(" - {0} Found",
search[bcl]);
return true;
}
else
{
System.Console. WriteLine(" - {0} Not found",
search[bcl]);
}
}
return false;
}
static void Main(string[] args)
{
int[] tempo=new int[3];
int[,] list = { { 1, 2, 3 } , { 11,12,13} };
int[] search = { 15, 123, 12 };
for (int bcl1 = 0; bcl1 < list.GetLength( 0); bcl1++) //
from 0 to 1 there is 2 array in list
{
for (int bcl = 0; bcl < list.GetLength( 1); bcl++) //
from 0 to 2 there is 3 elements in each array of list
{
tempo[bcl] = list[bcl1, bcl]; // I do convert a
multi array into a single array
System.Console. WriteLine("temp o[{0}]={1}", bcl,
tempo[bcl]);
}
if (contains(tempo , search))
System.Console. WriteLine("= FOUND ="); else
System.Console. WriteLine("= not FOUND ="); ;
System.Console. WriteLine("==== =============== =============== ==============" );
}
}
}

you can save yourself the binary search by using a Dictionary<int,
object> and store all ints in list 0 and list 1 in the key (and null in
the value) then do a dictionary.Cont ainsKey(value) for each value in
your array.

If I'm searching for an occurance of a value in a multi-dimensional
array how can I get it's index returned as an array, if found? For
example, if:
foo = new Array();
foo = , 5, , 9, 10];
Array.prototype.findValue = function(val) {

Hello,
I'm writing a function that updates an array. That is, given an
array, change each element.
The trick is this: I can't change any elements until I've processed
the entire array. For example, the manner in which I update element 1
depends on several other (randomly numbered) elements in the array.
So, I can't change an element until I've figured out how every element
changes.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
