System.Object
  System.Security.Cryptography.X509Certificates.X509ChainElementCollection

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

public sealed class X509ChainElementCollection : ICollection, 
	IEnumerable

The X509ChainElementCollection type exposes the following members.

  NameDescription
Public propertyCountGets the number of elements in the collection.
Public propertyIsSynchronizedGets a value indicating whether the collection of chain elements is synchronized.
Public propertyItemGets the X509ChainElement object at the specified index.
Public propertySyncRootGets an object that can be used to synchronize access to an X509ChainElementCollection object.

  NameDescription
Public methodCopyToCopies an X509ChainElementCollection object into an array, starting at the specified index.
Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetEnumeratorGets an X509ChainElementEnumerator object that can be used to navigate through a collection of chain elements.
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

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);
	
		foreach (X509ChainElement 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)
			{
				for (int index = 0; index < element.ChainElementStatus.Length; index++)
				{
					Console.WriteLine (element.ChainElementStatus[index].Status);
					Console.WriteLine (element.ChainElementStatus[index].StatusInformation);
				}
			}
		}
		store.Close();
