演示

此示例演示如何使用 IOrganizationService.RetrieveMultiple 方法检索组织的角色。 首先显示仅包含示例关键部分的片段，后面再显示完整示例代码。

示例

// 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);
    }

}
