RoleProvider.GetAllRoles Method ()
.NET Framework (current version)
Gets a list of all the roles for the configured applicationName.
Assembly: System.Web.ApplicationServices (in System.Web.ApplicationServices.dll)
Return Value
Type: System.String()A string array containing the names of all the roles stored in the data source for the configured applicationName.
GetAllRoles is called by the GetAllRoles method of the Roles class to retrieve a list of role names from the data source. Only the roles for the specified ApplicationName are retrieved.
If no roles exist for the configured applicationName, we recommend that your provider return a string array with no elements.
The following code example shows a sample implementation of the GetAllRoles method.
Public Overrides Function GetAllRoles() As String() Dim tmpRoleNames As String = "" Dim conn As OdbcConnection = New OdbcConnection(connectionString) Dim cmd As OdbcCommand = New OdbcCommand("SELECT Rolename FROM Roles " & _ " WHERE ApplicationName = ?", conn) cmd.Parameters.Add("@ApplicationName", OdbcType.VarChar, 255).Value = ApplicationName Dim reader As OdbcDataReader = Nothing Try conn.Open() reader = cmd.ExecuteReader() Do While reader.Read() tmpRoleNames &= reader.GetString(0) & "," Loop Catch e As OdbcException ' Handle exception. Finally If Not reader Is Nothing Then reader.Close() conn.Close() End Try If tmpRoleNames.Length > 0 Then ' Remove trailing comma. tmpRoleNames = tmpRoleNames.Substring(0, tmpRoleNames.Length - 1) Return tmpRoleNames.Split(CChar(",")) End If Return New String() {} End Function
