The GetCredential method returns a NetworkCredential instance that contains the credentials that are associated with the specified URI and authorization scheme. When no credentials are available, the GetCredential method returns null.

The following uses GetCredential to retrieve a NetworkCredential instance.

class CredentialList : ICredentials
	class CredentialInfo
		public Uri uriObj;
		public String authenticationType;
		public NetworkCredential networkCredentialObj;

		public CredentialInfo(Uri uriObj, String authenticationType, NetworkCredential networkCredentialObj)
			this.uriObj = uriObj;
			this.authenticationType = authenticationType;
			this.networkCredentialObj = networkCredentialObj;

	private ArrayList arrayListObj;

	public CredentialList()
		arrayListObj = new ArrayList();

	public void Add (Uri uriObj, String authenticationType, NetworkCredential credential)
		// Add a 'CredentialInfo' object into a list.
		arrayListObj.Add (new CredentialInfo(uriObj, authenticationType, credential));      
	// Remove the 'CredentialInfo' object from the list that matches to the given 'Uri' and 'AuthenticationType'
	public void Remove (Uri uriObj, String authenticationType)
		for(int index=0;index < arrayListObj.Count; index++)
			CredentialInfo credentialInfo = (CredentialInfo)arrayListObj[index];
			if(uriObj.Equals(credentialInfo.uriObj)&& authenticationType.Equals(credentialInfo.authenticationType))
	public NetworkCredential GetCredential (Uri uriObj, String authenticationType)
		for(int index=0;index < arrayListObj.Count; index++)
			CredentialInfo credentialInfoObj = (CredentialInfo)arrayListObj[index];
			if(uriObj.Equals(credentialInfoObj.uriObj) && authenticationType.Equals(credentialInfoObj.authenticationType))
				return credentialInfoObj.networkCredentialObj;
		return null;
