Problem : Get a list of user belonged to a role or to know if a user already has a role
What code can I write to know if a user belonged to a Role already ? and How can I get a list of a user already in an existing role ? Please have a look at my code below :
Protected Sub AddUsers_OnClick(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnAddUsersToRole.Click
' I wanna add some code here to check if a user already belonged to a Role
' Please insert your code here. Thanks a lot.
' A role must be selected
If RolesListBox.SelectedItem Is Nothing Then
Msg.Text = "Please select a role."
Exit Sub
End If
' At least one user must be selected
If UsersListBox.SelectedItem Is Nothing Then
Msg.Text = "Please select one or more users."
Exit Sub
End If
' Create list of users to be added to the selected role
Dim sizeOfArray As Integer = UsersListBox.GetSelectedIndices.Length
Dim newUsers(sizeOfArray - 1) As String
'For i As Integer = 0 To newusers.Length - 1
' newusers(i) = _
' UsersListBox.Items( _
' UsersListBox.GetSelectedIndices( )(i)).Value
'Next
For i As Integer = 0 To newUsers.Length - 1
' get the array of selected indices from the (multiselect) list box
Dim selectedIndices As Integer() = UsersListBox.GetSelectedIndices()
' get the selectedIndex that corresponds to the counter (i)
Dim selectedIndex As Integer = selectedIndices(i)
' get the ListItem in the UserListBox Items collection at that offset
Dim myListItem As ListItem = UsersListBox.Items(selectedIndex)
' get the string that is that ListItem's value property
Dim newUser As String = myListItem.Value
' add that string to the newUsers collection of string
newUsers(i) = newUser
Next
' Add users to the selected role
Roles.AddUsersToRole(newUsers, RolesListBox.SelectedItem.Value)
usersInRole = Roles.GetUsersInRole(RolesListBox.SelectedItem.Value)
UsersInRoleGrid.DataSource = usersInRole
UsersInRoleGrid.DataBind()
End Sub
it worked as it was supposed to. But how can I check if user is already belonged to a Role ?
Thanks a lot !

Hi,
The RoleModelProvider has two functions for this:
// Summary: // Gets a value indicating whether the currently logged-on user is in the specified // role. // // Parameters: // roleName: // The name of the role to search in. // // Returns: // true if the currently logged-on user is in the specified role; otherwise, // false. // // Exceptions: // System.Configuration.Provider.ProviderException: // Role management is not enabled. // // System.ArgumentNullException: // roleName is null.-or-There is no current logged-on user. // // System.ArgumentException: // roleName is an empty string or contains a comma (,). Roles.IsUserInRole(string roleName);// Summary: // Gets a value indicating whether the specified user is in the specified role. // // Parameters: // username: // The name of the user to search for. // // roleName: // The name of the role to search in. // // Returns: // true if the specified user is in the specified role; otherwise, false. // // Exceptions: // System.ArgumentNullException: // roleName is null.-or-username is null. // // System.Configuration.Provider.ProviderException: // Role management is not enabled. // // System.ArgumentException: // roleName is an empty string or contains a comma (,).-or-username contains // a comma (,). Roles.IsUserInRole(userName, roleName)Cheers,
Matthias :)

Asp.net has following two methods:
RoleProvider.GetUsersInRole Method
http://msdn2.microsoft.com/en-us/library/system.web.security.roleprovider.getusersinrole.aspx
RoleProvider.IsUserInRole Method
http://msdn2.microsoft.com/en-us/library/system.web.security.roleprovider.isuserinrole.aspx
