我遇到了一些我认为有点奇怪的问题。我收到两个＆＃34;在当前背景下不存在＆＃34;错误
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，项目构建/编译得很好并且应该运行。话虽如此，由于这个错误，我没有获得我想要的对象的智能感知。
我最近对XAML进行了大量编辑，所以我认为它与之有关，因为之前没有出现错误（实际上，＆＃39; employeeDetails＆＃39;当时不存在，但是＆＃39 ; searchBox＆＃39;做了）。 Grid和TextBox显然是非常基本的控件，所以我看不出它与我的引用或命名空间的错误。
我真诚地感谢任何帮助。
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（抱歉长度，但我担心如果我修剪它，我可能会删除故障代码）：

除清洁解决方案外，您还可以检查/清空obj\debug文件夹。我可能错了，但我认为Visual Studio设计师使用了其中的几个文件。
另外，根据this，在自定义命名空间声明的末尾添加;assembly=可以解决问题：
xmlns:local="clr-namespace:Insurance_MidAm_Interface;assembly="
