我在代码中做了一些代码更改,比如将值赋给Nullable字节类型变量。
现在,当我尝试构建我的应用程序时,我收到一条错误消息,并且构建不成功。我正在使用visual studio 2012.这是我得到的错误消息
Exception Message: Value cannot be null.
Parameter name: path (type ArgumentNullException)
Exception Stack Trace:at System.Activities.Statements.Throw.Execute(CodeActivityContext context)
at System.Activities.CodeActivity.InternalExecute(ActivityInstance instance, ActivityExecutor executor, BookmarkManager bookmarkManager)
at System.Activities.Runtime.ActivityExecutor.ExecuteActivityWorkItem.ExecuteBody(ActivityExecutor executor, BookmarkManager bookmarkManager, Location resultLocation)
有没有其他人经历过同样的事情?请帮忙。
