Question

我有以下代码：

var tfs = new TfsTeamProjectCollection(new Uri(TFS_SERVER_URL));    
tfs.EnsureAuthenticated();

var query = GetQuery(...)
var identities = ims.ReadFilteredIdentities(query, 5000, null, true, (int)MembershipQuery.None);
foreach (var item in identities.Items)
{
    Console.WriteLine("{0,-20} {1,-20} {2}", item.DisplayName, item.UniqueName, item.GetAttribute("Mail", null));
}

现在，当查询类似于

时

Microsoft.TeamFoundation.Identity.Type == 'User' AND (Microsoft.TeamFoundation.Identity.DisplayName CONTAINS 'alice' OR Microsoft.TeamFoundation.Identity.DisplayName CONTAINS 'bob')

代码抛出以下异常：

Microsoft.TeamFoundation.Framework.Client.IdentityExpressionException: TF400819: Query Expression is not well-formed 
---> System.Web.Services.Protocols.SoapException: TF400819: Query Expression is not well-formed

但是，如果我只搜索一个用户模式，例如：

Microsoft.TeamFoundation.Identity.Type == 'User' AND Microsoft.TeamFoundation.Identity.DisplayName CONTAINS 'mark'

它运作得很好。

所以，我的问题 - 可以在TFS Api中搜索多个用户模式，还是我被迫分别对每个模式重复查询？

Answer 1

不，你不能。＆＃34; OR＆＃34;查询表达式不支持运算符。有关详细信息，请参阅本文中ReadFilteredIdentities（）方法的说明：TeamFoundationIdentityService Class。

ReadFilteredIdentities用于检索一组身份在一个表达。表达式是一种类似于SQL的语法 WHERE子句。有关表达式功能的详细信息，请参阅 QueryExpression类的文档。这有两个部分表达。 可以使用一组值身份和他们必须在一起。

如何在TFS API中按多个用户模式进行过滤？
