我正在改编this snmp program from a user here on stackoverflow。我在Visual Studio 2022中做了一个新项目,添加了所有依赖项。
当我编译时,我得到6个IDE0090消息,但我看不到问题出在哪里。我已经将LangVersion
设置为10。

有人能看出问题出在哪里吗?

编译器建议,因为您显式指定了字段类型,而不是使用
var snmpVerb = ...
,所以不需要构造函数名称,并使用以下缩短的语法:如果您右键单击对
SimnpleSnmp
构造函数的调用并选择Quick Actions and Refactorings,它将为您提供一些建议,这是其中之一。b4wnujal2#
如IDE0090 docs所示,您可以使用C# 9 target-typed new expressions并简化示例创建。例如:
收件人:
或者只使用
var
:请注意,这些不是错误,而是信息性消息,不会影响程序的正确性/编译。
