Sample: Remove a role for a user

Applies To: CRM 2015 on-prem, CRM Online

This sample code is for Microsoft Dynamics CRM 2015 and Microsoft Dynamics CRM Online 2015 Update. Download the Microsoft Dynamics CRM SDK package. It can be found in the following location in the download package:

SampleCode\CS\BusinessDataModel\UsersAndRoles\RemoveRoleFromUser.cs

Requirements

For more information about the requirements for running the sample code provided in this SDK, see Use the sample and helper code.

Demonstrates

This sample shows how to disassociate a role from a user by using the IOrganizationService.Disassociate method. A snippet showing just the key sections of the sample is shown first, followed by the complete sample code. Note that this sample can only be run in an on-premises environment because it creates a user. However, the section of the sample that demonstrates disassociating a role from a user will work for all environments.

Example


// Connect to the Organization service. 
// The using statement assures that the service proxy is properly disposed.
using (_serviceProxy = new OrganizationServiceProxy(serverConfig.OrganizationUri, serverConfig.HomeRealmUri,serverConfig.Credentials, serverConfig.DeviceCredentials))
{
    _serviceProxy.EnableProxyTypes();

    CreateRequiredRecords();

    // Retrieve a user.
    SystemUser user = _serviceProxy.Retrieve(SystemUser.EntityLogicalName,
        _userId, new ColumnSet(new String[] { "systemuserid", "firstname", "lastname" })).ToEntity<SystemUser>();

    if (user != null)
    {
        Console.WriteLine("{1} {0} user account is retrieved.", user.FirstName, user.LastName);
        // Find the role.
        QueryExpression query = new QueryExpression
        {
            EntityName = "role",
            ColumnSet = new ColumnSet("roleid"),
            Criteria = new FilterExpression
            {
                Conditions =
                {
 
                    new ConditionExpression
                    {
                        AttributeName = "name",
                        Operator = ConditionOperator.Equal,
                        Values = {_givenRole}
                    }
                }
            }
        };

        // Get the role.
        EntityCollection roles = _serviceProxy.RetrieveMultiple(query);

        // Disassociate the role.
        if (roles.Entities.Count > 0)
        {
            Role salesRole = _serviceProxy.RetrieveMultiple(query).Entities[0].ToEntity<Role>();

            Console.WriteLine("Role {0} is retrieved.", _givenRole);

            _serviceProxy.Disassociate(
                        "systemuser",
                        user.Id,
                        new Relationship("systemuserroles_association"),
                        new EntityReferenceCollection() { new EntityReference("role", salesRole.Id) });
            Console.WriteLine("Role {0} is disassociated from user {1} {2}.", _givenRole, user.FirstName, user.LastName);
        }
    }

}
