X509ChainElementCollection Class

Represents a collection of X509ChainElement objects. This class cannot be inherited.

Namespace: System.Security.Cryptography.X509Certificates
Assembly: System (in system.dll)

Public NotInheritable Class X509ChainElementCollection
	Implements ICollection, IEnumerable
Dim instance As X509ChainElementCollection

public final class X509ChainElementCollection implements ICollection, IEnumerable
public final class X509ChainElementCollection implements ICollection, IEnumerable
Not applicable.

An instance of this class is returned when the ChainElements property is called.

The following code example opens the current user's personal certificate store, allows the user to select a certificate, and then writes certificate and certificate chain information to the console. The output depends on the certificate you select.

'Output chain element information.
Console.WriteLine("Chain Element Information")
Console.WriteLine("Number of chain elements: {0}", ch.ChainElements.Count)
Console.WriteLine("Chain elements synchronized? {0} {1}", ch.ChainElements.IsSynchronized, Environment.NewLine)

Dim element As X509ChainElement
For Each element In ch.ChainElements
    Console.WriteLine("Element issuer name: {0}", element.Certificate.Issuer)
    Console.WriteLine("Element certificate valid until: {0}", element.Certificate.NotAfter)
    Console.WriteLine("Element certificate is valid: {0}", element.Certificate.Verify())
    Console.WriteLine("Element error status length: {0}", element.ChainElementStatus.Length)
    Console.WriteLine("Element information: {0}", element.Information)
    Console.WriteLine("Number of element extensions: {0}{1}", element.Certificate.Extensions.Count, Environment.NewLine)

    If ch.ChainStatus.Length > 1 Then
        Dim index As Integer
        For index = 0 To element.ChainElementStatus.Length
        Next index
    End If
Next element
