WebClientProtocol.Credentials Property
Assembly: System.Web.Services (in system.web.services.dll)
/** @property */ public ICredentials get_Credentials () /** @property */ public void set_Credentials (ICredentials value)
public function get Credentials () : ICredentials public function set Credentials (value : ICredentials)
Property Value
The ICredentials for the XML Web service client.When using the Credentials property, a XML Web service client must instantiate a class implementing ICredentials, such as NetworkCredential, and then set the client credentials specific to the authentication mechanism. The NetworkCredential class can be used to set authentication credentials using the basic, digest, NTLM and Kerberos authentication mechanisms.
When the Credentials property is set to CredentialCache.DefaultCredentials then the client negotiates with the server to do Kerberos and/or NTLM authentication depending on how the server is configured.
The following example is an ASP.NET Web Form, which calls an XML Web service named Math. Within the EnterBtn_Click function, the Web Form explicitly sets authentication credentials using the Credentials property. The user name, password and domain are passed into the constructor for the NetworkCredential class.
<%@ Page Language="C#" %> <%@ Import Namespace="System.Net" %> <html> <script language="C#" runat="server"> void EnterBtn_Click(Object Src, EventArgs E) { MyMath.Math math = new MyMath.Math(); // Obtain password from a secure store. String SecurelyStoredPassword = String.Empty; // Set the client-side credentials using the Credentials property. ICredentials credentials = new NetworkCredential("Joe",SecurelyStoredPassword,"mydomain"); math.Credentials = credentials; int total = math.Add(Convert.ToInt32(Num1.Text), Convert.ToInt32(Num2.Text)); Total.Text = "Total: " + total.ToString(); } </script> <body> <form action="MathClient.aspx" runat=server> Enter the two numbers you want to add and then press the Total button. <p> Number 1: <asp:textbox id="Num1" runat=server/> + Number 2: <asp:textbox id="Num2" runat=server/> = <asp:button text="Total" Onclick="EnterBtn_Click" runat=server/> <p> <asp:label id="Total" runat=server/> </form> </body> </html>
