Gets or sets security credentials for XML Web service client authentication.
Assembly: System.Web.Services (in System.Web.Services.dll)
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 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.
This example has a text box that accepts user input, which is a potential security threat. By default, ASP.NET Web pages validate that user input does not include script or HTML elements. For more information, see.
