Finding the index of first element in the array in C#
To find the index of first element in the array, the code is as follows −
Example
using System;
public class Demo {
public static void Main() {
string[] products = new string[] { "Andy", "Mark", "Gary", "Andre"};
Console.WriteLine("One or more name begin with 'A'? = {0}",
Array.Exists(products, ele => ele.StartsWith("A")));
Console.WriteLine("Is the array having fixed size? = " + products.IsFixedSize);
Console.WriteLine("Is the array read only? = " + products.IsReadOnly);
Console.WriteLine("Is the array synchronized? = " + products.IsSynchronized);
Console.WriteLine("Index of the 1st element = "+products.GetLowerBound(0));
}
}Output
This will produce the following output −
One or more name begin with 'A'? = True Is the array having fixed size? = True Is the array read only? = False Is the array synchronized? = False Index of the 1st element = 0
Example
Let us see another example −
using System;
public class Demo {
public static void Main() {
string[] products = new string[] { };
Console.WriteLine("Is the array having fixed size? = " + products.IsFixedSize);
Console.WriteLine("Is the array read only? = " + products.IsReadOnly);
Console.WriteLine("Is the array synchronized? = " + products.IsSynchronized);
Console.WriteLine("Index of the 1st element = "+products.GetLowerBound(0));
}
}Output
This will produce the following output −
Is the array having fixed size? = True Is the array read only? = False Is the array synchronized? = False Index of the 1st element = 0
