發行︰ 2017年1月

適用於： Dynamics 365 (online)、Dynamics 365 (on-premises)、Dynamics CRM 2016、Dynamics CRM Online

這個範例程式碼適用於 Microsoft Dynamics 365 (線上和內部部署)。下載 Microsoft Dynamics CRM SDK 套件。 可以在下列位置的下載套件中找到：

SampleCode\CS\BusinessDataModel\UsersAndRoles\RetrieveRolesForOrg.cs

需求

如需執行此 SDK 所提供範例程式碼的需求資訊，請參閱使用範例和 Helper 程式碼。

示範

這個範例將說明如何使用 IOrganizationService.RetrieveMultiple 方法擷取組織的角色。 首先只是顯示範例重點區段的程式碼片段，隨後為完整範例程式碼。

範例

// 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))
{
    QueryExpression query = new QueryExpression
    {
        EntityName = Role.EntityLogicalName,
        ColumnSet = new ColumnSet("name", "roleid")

    };

    EntityCollection entities = _serviceProxy.RetrieveMultiple(query);
    // Write the name and ID of each role to the console.
    foreach (Entity item in entities.Entities)
    {
        Role role = item.ToEntity<Role>();
        Console.WriteLine("Name: {0}. Id: {1}", role.Name, role.Id);
    }

}
