如何从单元测试中抛出和处理自定义异常

Question

我有自定义异常-->

    public CustomException(SerializationInfo info, StreamingContext context)
        : base(info, context)
    {  }

我正在为它写一个单元测试——>

    [TestMethod]
    [ExpectedException(typeof(CustomException))]
    public void TestCustomException()
    {
        throw new CustomException(info:SerializationInfo, context:StreamingContext);
    }

错误显示为 SerializationInfo 和 StreamingContext 是类型并且对于给定的上下文无效。

您能否让我知道从单元测试中抛出自定义异常的正确方法是什么？

这是运行单元测试的内容：

[TestMethod]
[ExpectedException(typeof(CustomException))]
public void TestCustomException()
{
        SerializationInfo info = new SerializationInfo(typeof(CustomException), new FormatterConverter());
        info.AddValue("ClassName", string.Empty);
        info.AddValue("ExceptionMethod", string.Empty);
        info.AddValue("HResult", 1);
        info.AddValue("Source", string.Empty);
        info.AddValue("Message", string.Empty);
        info.AddValue("InnerException", new ArgumentException());
        info.AddValue("HelpURL", string.Empty);
        info.AddValue("StackTraceString", string.Empty);
        info.AddValue("RemoteStackTraceString", string.Empty);
        info.AddValue("RemoteStackIndex", 0);    
        StreamingContext context = new StreamingContext()
        throw new CustomException(info,context);
}
