I want to find index of a character in char Array. I wrote below code, but I want
to use some library function/ LINQ to find the index rather than manually looping
through it. Is there any smarter way/ concise way I can achieve it.
Attempt:
var index = -1;
char[] x = { 'A', 'B', 'C', 'D' , 'E'};
for(int t = 0; t< x.Length; t++)
{
if (x[t] == 'E')
index = t;
}
Console.WriteLine($"Index is: {index}");
For this example, you could use Array.IndexOf.
char[] x = { 'A', 'B', 'C', 'D', 'E' };
Console.WriteLine($"Index is: {Array.IndexOf(x, 'E')}");
This is with LINQ :
char[] x = { 'A', 'B', 'C', 'D', 'E' };
var index = x.Select((c, i) => new {c, i}).SingleOrDefault(c => c.Equals('D')).i
with array class:
var index = Array.FindIndex(x, c=> c.Equals('E'));
O(n).
Use System.Linq FindIndex
char[] x = { 'A', 'B', 'C', 'D' , 'E'};
int index = x.ToList().FindIndex(c => c == 'E');
