To access the Permissions service and its methods, set a Web reference to http://Server_Name/[sites/][Site_Name/]_vti_bin/Permissions.asmx.

The following code example modifies the permissions to a list for the specified collection of existing users, site groups, and cross-site groups. The example assumes the existence of a local XML file that contains information about the users and groups, which is loaded into a System.Xml.XmlDocument object. This example requires that a using (C#) or Imports (Microsoft Visual Basic) directive be included for the System.Xml namespace

Web_Reference_Folder_Name.Permissions permService = new Web_Reference_Folder_Name.Permissions();
permService.Credentials= System.Net.CredentialCache.DefaultCredentials;

XmlDocument myDocument = new XmlDocument();
myDocument.Load("C:\\\\File_Name.xml");

XmlNode ndPermissions = myDocument.DocumentElement;

try
{
   permService.AddPermissionCollection("List_Name", "List", ndPermissions);
}

catch (System.Web.Services.Protocols.SoapException ex)
{
   MessageBox.Show(ex.Message + " \n::\n " + ex.Detail.OuterXml + " \n::\n " + ex.StackTrace);
}
