            SPWeb myWeb = mySite.OpenWeb();
            SPContext currentContext = SPContext.Current;
            string userEmail = "emailaddress"; // get from txtEmail.Text control
            string userName = Membership.GetUserNameByEmail(userEmail);
            Console.WriteLine("Your UserName is: " + userName);
        }

This code is retuning NULL. What am i doing wrong in this code. i am trying to get userID using email .

I meant to say. UserName is Null. Membership.GetUserNameByEmail is returning Null value.

The code is only Main. This is a void method. How can it return null?
What returns null?

Do you need to load the Membership details into Membership from somewhere before calling GetUserNameByEmail?
Is it possible "emailaddress" (not a valid email address) is not in Membership and the return value of null should be expected for this address?

no i don't. emailaddress is in the database. not matter which email i put in, result is Null.

Do you have the proper settings in the app.config file?

SPSite mySite = new SPSite("sitename");
SPWeb myWeb = mySite.OpenWeb();
SPContext currentContext = SPContext.Current;

You seem to be attempting to work with SharePoint without a proper understanding of it and how to work with it.

SPContext.Current has no meaning on a console application, there is no SharePoint context this code is running under. You are also not properly disposing of the SPSite object. And really, there is not need whatsoever you use any of this with the code you have given. Period.

My Config file settings is good. All the other stuff i put on , just for the hack.

This is the original code.

string userName = Membership.GetUserNameByEmail(userEmail );
if (userName != null)
Console.WriteLine("Your UserName is: " + userName);

else
Console.WriteLine(userEmail + " is not a member of this site");

Console.ReadLine();
}

Instead of posting code that has been given to you why don't you post the app.config. The settings may be there but are they correct?

This is .ascx File

C#

namespace UserByEmail
{
    public partial class UserByEmail : System.Web.UI.UserControl
    {
        string _User = "";
        protected void Page_Load(object sender, EventArgs e)
        {
            string _Email = _txtEmail.Text;
            _User = Membership.GetUserNameByEmail(_Email);
        }
        protected void Btn_Send_Click(object sender, EventArgs e)
        {
            Response.Write("This is the User : " + _User);
        }
    }
}
