Gets the number of elements in the collection.

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

public int Count { get; }

Property Value

Type: System.Int32

An integer representing the number of elements in the collection.

Use this property to determine how many elements are in the collection.

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);
