ICredentials Interface
.NET Framework (current version)
Provides the base authentication interface for retrieving credentials for Web client authentication.
Assembly: System (in System.dll)
| Name | Description | |
|---|---|---|
![]() | GetCredential(Uri, String) | Returns a NetworkCredential object that is associated with the specified URI, and authentication type. |
The ICredentials interface provides the GetCredential method to objects that supply network credentials to applications.
The following example illustrates how to use the ICredentials interface.
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)) arrayListObj.RemoveAt(index); } } 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; } };
