Question

var xrr = __arglist(Convert.ToUInt32(1), 
                    Convert.ToUInt32(2), 
                    Convert.ToUInt32(3));

上面的代码会使编译器在构建时崩溃。我希望编译器停止使用有意义的错误消息，而不是尝试编译代码。它可能是编译器中的错误吗？如果没有，我该如何解决这个错误？

Answer 1

这不是编译器中的错误;编译器给出了正确的错误信息相反，这是Visual Studio编辑器语言服务中的一个错误，导致Visual Studio崩溃。

但是，您的代码无论如何都是非法的; __arglist(...)表达式只能用于调用带__arglist的函数。

Answer 2

看起来像Visual Studio的问题，而不是编译器：

<强> VS2010

<强> System.AccessViolationException

尝试读取或写入受保护的内存。这通常表明其他内存已损坏。
