我有一个包含 TFS 构建的测试程序集统计信息的表，如下所示：

AssemblyName   Duration      TestResults    MsPerResult Branch
Ass1.dll            100                2             50     $/branch1
Ass2.dll            200                2            100     $/branch1/sub1
Ass3.dll            400                2            200     $/branch1/sub1/subsub1
...

另外，我有一个汇总类，用于保存 DataContext.ExecuteQuery<> 结果

public class AssemblyStatistics
{
    public string AssemblyName { get; set; }
    public int TestResultCount { get; set; }
    public long ValueInMs { get; set; }
}

如果我执行以下代码，我的查询总是需要相同的时间，即使我限制结果只查询一个子分支：

context.ExecuteQuery<AssemblyStatistics>(
  "SELECT TOP 10 AssemblyName, SUM(Duration) AS ValueInMs, SUM(TestResults) AS TestResultCount FROM AssembliesByDuration WHERE Branch LIKE {0} GROUP BY AssemblyName ORDER BY SUM(Duration) DESC", "$/branch1/sub1%").ToList();

但是使用以下（非网络安全）格式，运行时按预期下降

context.ExecuteQuery<AssemblyStatistics>(
  @"SELECT TOP 10 AssemblyName, SUM(Duration) AS ValueInMs, SUM(TestResults) AS TestResultCount FROM AssembliesByDuration WHERE Branch LIKE '"
                  + "$/branch1/sub1%" + "' GROUP BY AssemblyName ORDER BY SUM(Duration) DESC").ToList();

我是否遗漏了什么，或者这只是 Linq2SQL 之后评估 LIKE 的问题？

在第一个查询中，您似乎缺少 {0} 周围的单引号。
