问题描述
我遇到了一个我认为有点奇怪的问题.我收到两个在当前上下文中不存在"的错误
I am running into what I consider a bit of an odd problem. I am receiving two "does not exist in current context" errors
Error 1 The name 'employeeDetails' does not exist in the current context c:\users\kelly\documents\visual studio 2013\projects\insurance midam interface\insurance midam interface\mainwindow.xaml.cs 72 17 Insurance MidAm Interface
Error 2 The name 'searchBox' does not exist in the current context c:\users\kelly\documents\visual studio 2013\projects\insurance midam interface\insurance midam interface\mainwindow.xaml.cs 80 34 Insurance MidAm Interface
然而，奇怪的是，该项目构建/编译得很好并且运行正常.话虽如此，由于这个错误，我没有在我想要的对象上获得智能感知.
However, the strange thing is, the project builds/compiles just fine and runs as it should. With that being said, due to this error, I am not getting IntelliSense on the objects which I would like to have.
我最近对 XAML 进行了大量编辑，因此我认为这与此有关，因为在那之前没有出现错误(实际上，当时不存在employeeDetails"，但searchBox"出现了).Grid 和 TextBox 显然是非常基本的控件，所以我看不出我的引用或命名空间会如何出错.
I recently made extensive edits to the XAML, so I presume it has something to do with that as the errors did not appear before then (actually, 'employeeDetails' did not exist then, but 'searchBox' did). Grid and TextBox are obviously quite basic controls, so I do not see how it would be an error with my references or namespaces.
我衷心感谢您的帮助.
相关的CS:
private void viewButton_Click(object sender, RoutedEventArgs e) {
DataRowView selectedValue = (DataRowView)employeeGrid.SelectedItem;
MessageBox.Show(selectedValue.Row[0].ToString());
employeeGrid.Visibility = Visibility.Collapsed;
employeeDetails.Visibility = Visibility.Visible;
}
private void searchBox_TextChanged(object sender, TextChangedEventArgs e)
{
String currentText = searchBox.Text;
ds.Tables["Employees"].DefaultView.RowFilter = "last like '" + currentText + "*'";
}
}
}
和XAML(对长度很抱歉，但我担心如果我修剪它，我可能会删除故障代码):
and the XAML (sorry about the length, but I am afraid that if I trim it, I may possibly be removing the trouble code):

推荐答案
在清理解决方案的基础上，您可以检查/清空 obj\debug 文件夹.我可能错了，但我认为 Visual Studio 设计器使用了其中的几个文件.
On top of cleaning the solution, you can check/empty the obj\debug folder. I might be wrong, but I think several files in there are used by the Visual Studio designer.
另外，根据this，添加;assembly= 在像这样的自定义命名空间声明的末尾可以解决问题:
Also, according to this, adding ;assembly= at the end of your custom namespace declaration like this could solve the problem:
xmlns:local="clr-namespace:Insurance_MidAm_Interface;assembly="
