10) getusernamebyemail (): queries the user name by email address

L membershipuser class

Manages and updates relevant materials in the membership table. Do not mix the membershipuser class with the membership class. It is actually handled by the membershipuser after it is processed. For example:

1) obtain or set user information. For example, username, email, and account creation time.

2) read and change the User Password

Code implementation (1)

Create a user:

Membershipcreatestatus MC;

Membership. createuser (txtuid. Text, txtpwd. Text, txtemail. Text, txtquestion. Text, txtanswer. Text, true, out MC );

Response. Write (MC. tostring ());

Delete A User:

If (membership. deleteuser (txtuid. Text ))

Response. Write ("OK ");

Else

Response. Write ("error ");

Modify user information:

If (user. Identity. isauthenticated)

{

Membershipuser user = membership. getuser ();

User. Email = txtemail. text;

Membership. updateuser (User );

Response. Write (user. Email. tostring ());

}

Verify User Logon Information

Bool isok = membership. validateuser (txtuid. Text, txtpwd. Text );

If (isok)

{

Formsauthentication. setauthcookie (txtuid. Text, false );

Response. Write ("OK ");

}

Else

{

Response. Write ("error ");

}

Obtain login user information

If (user. Identity. isauthenticated)

{

Membershipuser myuser = membership. getuser ();

If (myuser! = NULL)

{

Response. Write (myuser. creationdate );

Response. Write (myuser. Email );

Response. Write (myuser. islockedout );

Response. Write (myuser. isonline );

Response. Write (myuser. passwordquestion );

Response. Write (myuser. username );

}

}

Return the User Password Based on the answer to the password question

If (user. Identity. isauthenticated)

{

Membershipuser user = membership. getuser (txtuid. Text );

Txtpwd. Text = user. GetPassword (txtanswer. Text );

}

Change User Password

If (user. Identity. isauthenticated)

{

Membershipuser user = membership. getuser ();

User. changepassword (txtpwd. Text, txtpwd2.text );

Response. Write (user. GetPassword (txtanswer. Text ));

}

Unlock a user

Membershipuser user = membership. getuser (txtuid. Text );

Bool B = user. unlockuser ();

Response. Write (B + "" + User. islockedout );

User Logon denied

Membershipuser user = membership. getuser (txtuid. Text );

User. isapproved = false;

Membership. updateuser (User );

Response. Write (user. islockedout );

Allow User Login

Membershipuser user = membership. getuser (txtuid. Text );

User. isapproved = true;

Membership. updateuser (User );

Response. Write (user. islockedout );

Retrieve users by user name or email address

Membershipusercollection users;

Switch (listtype. Text)

{

Case "name ":

Users = membership. findusersbyname (txtfind. Text );

If (users. Count> 0)

{

Showuserinfo (users );

}

Else

{

Response. Write ("User Name Not Found ");

}

Break;

Case "email ":

Users = membership. findusersbyemail (txtfind. Text );

If (users. Count> 0)

{

Showuserinfo (users );

}

Else

{

Response. Write ("No email found ");

}

Break;

}

Code Implementation (2)

Load all users

Membershipusercollection user = membership. getallusers ();

Listuser. datasource = user;

Listuser. databind ();

Load all roles

String [] role = roles. getallroles ();

Listrole. datasource = role;

Listrole. databind ();

Roles. deleterole (txtrole. Text );

Add a user to a role

Roles. addusertorole (listuser. Text, listrole. Text );

Remove a user from a role

Roles. removeuserfromrole (listuser. Text, listrole. Text );

Add a user to multiple roles

Int n = 0;

Foreach (listitem Li in listrole. Items)

{

If (Li. Selected) n ++;

}

String [] roles = new string [N];

Int I = 0;

Foreach (listitem Li in listrole. Items)

{

If (Li. Selected)

{

Roles [I ++] = Li. text;

}

}

Roles. addusertoroles (listuser. Text, roles );

Remove all roles of a user

String [] STR = roles. getrolesforuser (listuser. Text );

Roles. removeuserfromroles (listuser. Text, STR );

Add multiple users to a role

Int n = 0;

Foreach (listitem Li in listuser. Items)

{

If (Li. Selected) n ++;

}

String [] users = new string [N];

Int I = 0;

Foreach (listitem Li in listuser. Items)

{

If (Li. Selected)

{

Users [I ++] = Li. text;

}

}

Roles. adduserstorole (users, listrole. Text );

Remove all users in a role

String [] users = roles. getusersinrole (listrole. Text );

Roles. removeusersfromrole (users, listrole. Text );

Add multiple users to multiple roles

Int n = 0;

Foreach (listitem Li in listuser. Items)

{

If (Li. Selected) n ++;

}

String [] struser = new string [N];

N = 0;

Foreach (listitem Li in listrole. Items)

{

If (Li. Selected) n ++;

}

String [] strroles = new string [N];

For (INT I = 0; I <listuser. Items. Count; I ++)

{

Struser [I] = listuser. items [I]. text;

}

For (INT I = 0; I <listrole. Items. Count; I ++)

{

Strroles [I] = listrole. items [I]. text;

}

Roles. adduserstoroles (struser, strroles );
