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 );

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 );

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;

}

}

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 );

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

Roles. removeuserfromroles (listuser. Text, STR );

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 );
