Array in C# Part 2 [ Sort Reverse , IndexOf , LastIndexOf ]

Hi *.*,

Before reading this pls go through part 1(Last post).

 Array Reverse 

 

int[] intArray = new int[] { 4, 1, 3,3, -23,-23,6 };

Array.Reverse(intArray);

Output

Array IndexOf

int[] intArray = new int[] { 4, 1, 3,3, -23,-23,6 };

int idx = Array.IndexOf(intArray, -23);

 Output

 Array LastIndexOf

int[] intArray = new int[] { 4, 1, 3,3, -23,-23,6 };

int lstidx = Array.LastIndexOf(intArray, -23);

Output

 Difference b\w IndexOf and LastIndexOf

 

The method indexOf() returns the first occurrence (index) of a given character or a combination as parameter in a given string.

The method lastIndexOf() returns the last occurrence (last index) of a given character or combination in a given string.

For ur easy understanding i had given same value for both method.

Hope u got all

Take care

Have a nice day... 'N happy Coding :)
