Answer 1

You can use JSOM by javascript like two different ways:

Using sp.js _spPageContextInfo.userLoginName

Or you could use REST

function getCurrentUser() {
    var endpointUrl = _spPageContextInfo.webServerRelativeUrl + '/_api/web/currentuser';
    return $.ajax({
            url: endpointUrl,
            method: "GET",
            contentType: "application/json;odata=verbose",
            headers: {   
             "Accept": "application/json;odata=verbose"
            } 
        }); }

There are many ways to get logged in user name

SPWeb site = SPControl.GetContextWeb(Context);
SPUser user = site.CurrentUser;
string strUserName = user.LoginName;

or you can use

SPWeb web = SPControl.GetContextWeb(this.Context);
string userName = web.CurrentUser.LoginName;

or you also can use

string userName = this.Context.User.Identity.Name;
