Question

是否可以同时使用变量和字符串？例如，我想定义结合变量和字符串的路径和其他选项？

private void ComboBox_PreviewKeyDown(object sender, KeyEventArgs e)
{
    var cb = sender as ComboBox;

    if ((e.Key == Key.Return ||
        e.Key == Key.Enter) &&
        cb.Text != "")
    {
        bool duplicate = false;
        foreach (ClockGroupVM vm in Clocks.GroupsVM)
        {
            if (vm.Name == cb.Text)
            {
                cb.SelectedItem = vm;
                duplicate = true;
                break;
            }
        }

        if (duplicate)
        {
            return;
        }

        // create a ClockGroupM and corresponding ClockGroupVM
        // (ClockGroupVM inherits from ClockGroupM)
        var cvm = new ClockGroupVM()
        {
            Name = cb.Text
        };
        Clocks.Groups.Insert(0, cvm);
        cb.SelectedItem = cvm;
    }
}

internal bool HandlingSelectionChange = false;
private void ComboBox_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
    if (HandlingSelectionChange)
    {
        return;
    }
    HandlingSelectionChange = true;

    var cb = sender as ComboBox;

    //if (cb.SelectedItem is the VM with Style != Normal)

    ClockGroupVM foundVM = null;
    foreach (ClockGroupVM vm in Clocks.GroupsVM)
    {
        if (vm.FontStyle != FontStyles.Normal &&
            ReferenceEquals(cb.SelectedItem, vm))
        {
            foundVM = vm;
            break;
        }
    }

    if (foundVM != null)
    {
        cb.Text = "";
        e.Handled = true;
    }

    HandlingSelectionChange = false;
}

当然有一个简单的答案，但一时找不到答案

Answer 1

path 的声明应使用单引号（'）。那么反斜杠（\）将不会被解释为转义字符。参见Gotchas

单引号和双引号之间的区别在于，在双引号中可以使用转义符

path: '{{ directory_path }}\AppName-{{ env }}'

代码缩进是错误的。正确的语法如下

tasks:
    #Add Directory
  - name: Add Directory
    win_file:
      path: '{{ directory_path }}\AppName-{{ env }}'
      state: directory
    #Add IUSR to directory path
  - name: ADD IUSR
    win_acl:
      path: '{{ directory_path }}\AppName-{{ env }}'
      user: IUSR
      rights: Read
      type: allow
      state: present
      propagation: 'NoPropagateInherit'
    #Add website
  - name: "{{ env }} Add App Name"
    win_iis_website:
      name: "AppName-{{ env }}"
      state: started
      port: 80
      ip: "{{ serverip }}"
      hostname: "appname-{{ env }}.com"
      application_pool: "{{ application_pool4 }}"
      physical_path: '{{ directory_path }}\AppName-{{ env }}'
    register: website

用 ansible-lint 测试剧本是个好主意。
