使用 Team Foundation 的用戶端物件模型，為不同的工作項目類型撰寫程式碼
當您為不同的 Team 專案中撰寫程式碼時，您可以執行以類似的用途不同工作項目類型的相同的函式。 這些型別可能不同，因為它們是來自不同的流程範本，或是小組可能已經自訂它們對特定 Team 專案。 例如，您可能會想要執行使用者劇本和要求的相同功能，都應該代表哪些客戶需求和值。 而是工作項目類型的文字不同的程式碼，您可以推斷您的程式碼對這兩個工作。 此外，一個小組可能已經自訂使用者劇本的工作項目類型定義，小組成員可以估計工作時數 (而非在劇本點。 您可以避免複製您的工作以及藉由調整您的程式碼來處理預設和自訂的策略。
在本主題中，您可以執行工作項目類型的特定類型的工作尚未自訂的程式碼範例，您可以學習如何重構該程式碼支援特定型別的自訂。 如需如何自訂工作項目類型的詳細資訊，請參閱 自訂 Team 專案和流程。

列印使用者劇本樹狀結構與評量的劇本點。
這個程式碼範例會列印所有使用者劇本樹狀結構中每一個 Team 專案的伺服器上並包含沒有子系的每個劇本的估計值。 若要使用此範例，請建立主控台應用程式中，加入下列組件的參考，然後以下列程式碼取代 Program.cs (或 Module1.vb) 的內容。

列印使用者劇本樹狀結構與在估計劇本點或基準工作
這個範例修改 PrintTrees 方法決定每個工作項目類型是否使用劇本點欄位或基準工作欄位和列印從該欄位的估計值。 若要使用此範例，您可以使用下列程式碼取代 PrintTrees 方法的程式碼行 Console.WriteLine(target.Fields["Story Points"].Value); 。
// Determine which estimation field is present
string fieldName = "Story Points";
if (target.Type.FieldDefinitions.TryGetByName(fieldName) == null)
{
fieldName = "Baseline Work";
}
Console.WriteLine(target.Fields[fieldName].Value);

您可以經過分類會因相同或相似用途不同 Team 專案中工作項目的類型。 您可以撰寫程式碼來執行在所屬的分類中的所有工作項目相同的函式。 這個範例會列印任何類型的工作項目類型的估計值會在要求的分類，例如使用者劇本、需求和產品待處理項目。
