对于“ Visual Studio Team Test”，您似乎将ExpectedException属性应用于该测试的方法。

这里的文档样本：使用Visual Studio Team Test进行单元测试的演练

[TestMethod]
[ExpectedException(typeof(ArgumentException),
    "A userId of null was inappropriately allowed.")]
public void NullUserIdInConstructor()
{
   LogonInfo logonInfo = new LogonInfo(null, "P@ss0word");
}
