Here is my code:
int Temp = 200;
List<int> PrimeBuilders = new List<int>();
PrimeBuilders.Add(200);
PrimeBuilders.Add(300);
PrimeBuilders.Add(400);
PrimeBuilders.Add(500);
PrimeBuilders.Add(200);
PrimeBuilders.Add(600);
PrimeBuilders.Add(400);
foreach(int A in PrimeBuilders)
{
}
How can I go through the list and output the index that does not contain the number assigned to Temp?
If you need indexed you probably should go with for instead of foreach:
for(int i = 0; i < PrimeBuilders.Count; i++)
{
if(PrimeBuilders[i] != Temp)
Console.WriteLine(i.ToString());
}
Bonus: LINQ one-liner:
Console.WriteLine(String.Join(Environment.NewLine, PrimeBuilders.Select((x, i) => new { x, i }).Where(x => x.x != Temp).Select(x => x.i)));
foreach(var item in PrimeBuilders.Select((x, i) => new { x, i }))... if foreach is required.What you need is:
int Temp = 200;
var PrimeBuilders = new List<int> {200, 300, 400, 500, 200, 600, 400};
for (int i = 0; i < PrimeBuilders.Count; i++)
{
Console.WriteLine("Current index: " + i);
if (PrimeBuilders[i] != Temp)
{
Console.WriteLine("Match found at index: " + i);
}
}
Firstly, you can initialize your list with 1 line. Secondly, if you need an index, then foreach will not give you that. You need a for loop, as shown above.
foreachdoesn't really deal with indexes, you'd be better to use a for loop, or maintain your own counter.
