Asp.net method for obtaining the value of the logged-on user loginname, that is, the value of the logged-on user username

I use the user management system, such as register and log on, that comes with my own website created by vs2010. The function to be created includes the upload Resource function.
When uploading a resource, you need to record the User Name of the uploaded person. Then, you can use the database to find the uploaded resource based on the user name of the uploaded person.

How can I obtain the username of a successfully logged-on user during programming in the. CS file?

Use context. User. Identity. Name!

For example, string uploadusername = context. User. Identity. Name;
The username stored in the table in the membership database is stored in the uploadusername variable.

Others on the Internet use page. User. Identity. Name, and no value is obtained.
