Best way to get Query string from url in SharePoint / Asp .Net / webApps

The easiest and well know way is to Request.QueryString[“name”]; but many times to get null exception we should check query string and return in appropriate format. Below I have created a private int variable and protected property of it. You can have a look on below code.

protected int ItemID

        {

            get

            {

                if (Request.QueryString["itemId"] != null && Request.QueryString["itemId"].Length > 0)

                {

                    return Convert.ToInt32(Request.QueryString["itemId"]);

                }

                else return 0;

            }

        }
