Escrevendo código para diferentes tipos de itens de trabalho usando o modelo de objeto de cliente para o team foundation
Quando você escrever código para projetos de equipe diferentes, você pode executar a mesma função em diferentes tipos de itens de trabalho que servem fins semelhantes.Esses tipos podem ser diferentes porque vêm dos diferentes modelos de processo, ou uma equipe podem tê-los personalizado para um projeto de equipe específico.Por exemplo, você pode desejar executar a mesma função em artigos e dos requisitos do usuário, os que devem representar clientes exigem e valores.Em vez de escrever código separado para cada tipo de item de trabalho, você pode generalizar seu código para funcionar para ambos.Além de isso, uma equipe pode ter personalizado a definição de item de trabalho para artigos do usuário para que os membros da equipe possam estimar o trabalho na hora em vez dos pontos de essa história.Você pode evitar duplicar seu próprio esforço ajustar seu código para tratar a opção e as estratégias personalizados.
Em este tópico, você pode localizar um exemplo de código que executa uma tarefa em um determinado tipo de item de trabalho que não foi personalizado e em seguida, você pode aprender como refatorar a codificação para suportar certas tipos das personalizações.Para obter mais informações sobre como personalizar os tipos de itens de trabalho, consulte Personalizar projetos de equipe e processos.

Imprimir árvores de artigos de usuário com avaliações em pontos de essa história
Imprimir árvores de artigos de usuário com avaliações em pontos de trabalho artigo ou na linha de base
Imprimir árvores de itens de trabalho que são usados como requisitos com avaliações
Imprimir árvores de artigos de usuário com avaliações em pontos de essa história
Esta exemplo de código lê árvores de todas as histórias de usuário em cada projeto de equipe em um servidor e inclui avaliações para cada artigo que não tem filhos.Para usar este exemplo, você cria um aplicativo de console, adicione referências para os seguintes conjuntos e em seguida, substitui o conteúdo de Module.vb (ou Module1.vb) com o código a seguir.

Imprimir árvores de artigos de usuário com avaliações em pontos de trabalho artigo ou na linha de base
Este exemplo altera o método de PrintTrees para determinar se cada item de trabalho usa os pontos de essa história coloca ou o campo de trabalho da linha de base e para imprimir a avaliação do campo.Para usar este exemplo, você substitui a linha Console.WriteLine(target.Fields["Story Points"].Value); no método de PrintTrees com o código a seguir.
// 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);

Árvores de impressão de todas funcionam itens em uma categoria
Você pode agrupar categorias em diferentes tipos de itens de trabalho que servem as mesmas as finalidades semelhantes em projetos de equipe diferentes.Você pode escrever código para executar a mesma função em todos os itens de trabalho que pertencem a uma categoria.Este exemplo imprime avaliações para qualquer tipo de item de trabalho na categoria dos requisitos, como as histórias de usuário, requisitos, e itens de retorno do produto.
Para usar este exemplo, substitua a função do exemplo anterior com o código a seguir.
