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);
}
}
