SharePoint How to get SPUser from list item C#

How to get SPUser from list item, SharePoint list item get user, how to get created, modified, Author or Editor from sharepoint list, how to get LoginName or Email of User from list,

Well there is another way to get Web. EnsureUser(“User”); it returns SPUser object as well it adds user in site directly if do not already that web user, another way to get it write a function that return SPUser object,   

*Assuming that you are aware how to get SPWeb and List then List item,

SPUser oUserSubmittedBy = GetSPUser(oItem, “fieldDisplay Name”);

Here is the function body.

Code:

protected SPUser GetSPUser(SPListItem item, string user)

        {

            SPUser oUser = null;

            SPFieldUserValue userValue = new SPFieldUserValue(item.Web, Convert.ToString(item[user]));

            if (userValue != null)

            {

                oUser = userValue.User;

            }

            return oUser;

        }

And once you get object you can get Name, email and login name

oUserSubmittedBy.LoginName

oUserSubmittedBy.Name

oUserSubmittedBy.Email…. etc..

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;

            }

        }
