You can simply do this using jQuery ajax:-

var dataToSend = { "Data": list};
$.ajax({
           type: "POST",
           dataType: "json",
           contentType: "application/json; charset=utf-8",
           url: "Default.aspx/SaveData",
           data: JSON.stringify(dataToSend),
           success: function (msg) {
                //success data if any 
           },
           error: function (msg) { //handle error here }
     });

Add this method in your page behind (Default.aspx.cs):-

[WebMethod]
public static void SaveData(string[] Data)
{
     //Save data to DB
}
