Reading Query string Values in Javascript

Using simple javascript to get the  query string value of URL.

We have URL as 

<a href="DisplayContent.html?id=0"> 0</a>

<a href="DisplayContent.html?id=1">1</a>

To Read the content of URL you can use below method as;

function getParameterValueByName(name, url) {

        if (!url) url = window.location.href;

        name = name.replace(/[\[\]]/g, "\\$&");

        var regex = new RegExp("[?&]" + name + "(=([^&#]*)|&|#|$)"),

            results = regex.exec(url);

        if (!results) return null;

        if (!results[2]) return '';

        return decodeURIComponent(results[2].replace(/\+/g, " "));

    }

Convert Object to DataTable in C#

Converting object to datatable using the C# code, it help in many places like doing the bulk insertion of data to database. There we need to send data in the form of table.

Suppose we have an Employee Class.

public class Employee

    {

        public int EmployeeId { get; set; }

        public string EName { get; set; }

        public int Age { get; set; }

        public decimal Salary { get; set; }

    }

Now instead of creating method for converting the object to datable, we will create a generic extension method which will convert any type of object into datatable.
