Pass array from client side to service side c#

Question

I am calling a javascript function on button click using onclientclick with below function.

 

function addValues() {

var arrValue = [];

var hdnValue = document.getElementById("hdn").value;

var strValue = hdnValue.split(',');

for (var i = 0; i < strValue.length; i++)

{

var ddlValue = document.getElementById(strValue[i]).value;

arrValue.push(ddlValue);

}

}

 

arrValue array will have all the required values and how can I move this array values to server side for further process.
