调试时无法设置下一条语句 [英] Unable to set next statement when debugging

问题描述

我正在VS2015中调试我的项目，并且在我的代码中引发了异常。
当我尝试设置下一条语句时，出现以下错误信息。当我在VS2013中调试相同的解决方案时，我可以设置下一条语句而不会出现任何问题。

I am debugging my project in VS2015 and an exception is thrown in my code. When I try to set the next statement I get the error message displayed below. When I debug the same solution in VS2013 I am able to set the next statement without any problems. This behavior seems to occur for multiple kinds of exceptions.

我可以重现该问题的示例代码如下所示。当在 TestMethod1 的最后一行抛出异常时，我可以轻松地移回VS2013中的第一条语句，而不能回到VS2015中。

Example code that I can reproduce the problem with is shown below. When an exception is thrown on the last line in TestMethod1 I can easily move back to the 1st statement in VS2013 but not in VS2015.

[TestClass]
public class UnitTest1
{
    [TestMethod]
    public void TestMethod1()
    {
        object o = new object();
        o = null;
        var e = o.ToString();
    }
}

推荐答案

在在例外设置中，您需要为要抛出的特定CLR例外类型启用抛出时中断，或者<不在此列表中的所有公共语言运行时例外。自定义例外。在此特定示例中，启用 System.NullReferenceException 应该允许您按预期设置下一条语句。

In Exception Settings, you need to enable Break When Thrown for the particular CLR exception type that is being thrown, or <All Common Language Runtime Exceptions not in this list> for custom exceptions. In this particular example, enabling System.NullReferenceException should allow you to set next statement as expected.

您希望在不破坏所有未列出的CLR异常的情况下打破的特定自定义异常，可以将它们添加到异常设置中的列表中，并进行相应选择。

If there are particular custom exceptions you want to break on without breaking on all unlisted CLR exceptions, you can add them to the list in Exception Settings and choose accordingly.
