int [] marks = new int[5] { 99, 98, 92, 97, 95};

Explanation: marks is the name of array which datatype is int and the size is 5. The value written in {} braces are the element of array which can be accessed by their position as below.

Console.WriteLine("Your marks at position 0 is: " + marks[0]);

The output will be as follows:

Your marks at position 0 is: 99

Hi, First create an array in correct formats then get the data using foreach or for loop loop. int[] array = { 10, 30, 50 }; //array declaration foreach (int element in array) { Console.WriteLine(element); }

var columnArray=['jfhd','dfdf','dfdf','sdfsd']
if(columnArray.indexOf('jfhd')!=-1)//
{
}

Array.indexOf('value')-method returns -1 if element is not found else it return index of the element/value.

if you are using javascript then try :
if(columnArray.includes('jfhd'))
{

}

Hi Venkat,

write the forloop for it,

var columnArray=['jfhd','dfdf','dfdf','sdfsd']

for(var i=0;i
{
if(columnArray[i]=='dfdf')
{
//write your logic here
}
}

In simple term , use jquery to check the value in array

if(jQuery.inArray("dfdf",columnArray)!==-1)
{
//write your logics here
}
