Visual Studio 2008
Represents a collection of string elements separated by commas. This class cannot be inherited.
Assembly: System.Configuration (in System.Configuration.dll)
The following code example demonstrates how to use the CommaDelimitedStringCollection type.
Imports System Imports System.Collections.Generic Imports System.Text Imports System.Configuration Imports System.Collections Imports System.Web Imports System.Web.Configuration Imports System.Collections.Specialized Namespace Samples.AspNet.Config Class CommaDelimitedStrCollection Shared Sub Main(ByVal args() As String) ' Display title and info. Console.WriteLine("ASP.NET Configuration Info") Console.WriteLine("Type: CommaDelimitedStringCollection") Console.WriteLine() ' Set the path of the config file. Dim configPath As String = "/aspnet" ' Get the Web application configuration object. Dim config As Configuration = _ WebConfigurationManager.OpenWebConfiguration(configPath) ' Get the section related object. Dim configSection As AuthorizationSection = _ CType(config.GetSection("system.web/authorization"), AuthorizationSection) ' Get the authorization rule collection. Dim authorizationRuleCollection As AuthorizationRuleCollection = _ configSection.Rules() ' Create a CommaDelimitedStringCollection object. Dim myStrCollection As CommaDelimitedStringCollection = _ New CommaDelimitedStringCollection() Dim i As Integer For i = 0 To authorizationRuleCollection.Count - 1 Step i + 1 If authorizationRuleCollection.Get(i).Action.ToString().ToLower() _ = "allow" Then ' Add values to the CommaDelimitedStringCollection object. myStrCollection.AddRange( _ authorizationRuleCollection.Get(i).Users.ToString().Split( _ ",".ToCharArray())) End If Next Console.WriteLine("Allowed Users: {0}", _ myStrCollection.ToString()) ' Count the elements in the collection. Console.WriteLine("Allowed User Count: {0}", _ myStrCollection.Count) ' Call the Contains method. Console.WriteLine("Contains 'userName1': {0}", _ myStrCollection.Contains("userName1")) ' Determine the index of an element ' in the collection. Console.WriteLine("IndexOf 'userName0': {0}", _ myStrCollection.IndexOf("userName0")) ' Call IsModified. Console.WriteLine("IsModified: {0}", _ myStrCollection.IsModified) ' Call IsReadyOnly. Console.WriteLine("IsReadOnly: {0}", _ myStrCollection.IsReadOnly) Console.WriteLine() Console.WriteLine("Add a user name to the collection.") ' Insert a new element in the collection. myStrCollection.Insert(myStrCollection.Count, "userNameX") Console.WriteLine("Collection Value: {0}", _ myStrCollection.ToString()) Console.WriteLine() Console.WriteLine("Remove a user name from the collection.") ' Remove an element of the collection. myStrCollection.Remove("userNameX") Console.WriteLine("Collection Value: {0}", _ myStrCollection.ToString()) ' Display and wait Console.ReadLine() End Sub End Class End Namespace
