在WPF TextBox中显示“当前工作目录”

Could someone please tell me how to display the path of the current working directory in a textbox using C# and WPF?

有人可以告诉我如何使用C#和WPF在文本框中显示当前工作目录的路径?

I don't understand how I can bind to it.

我不明白我怎么能绑定它。

3 个解决方案

#1

1. In ViewModel/View's code behind:

   在ViewModel / View的代码背后:

   public string CurrentDirectoryPath
   {
      get 
      { 
          return Environment.CurrentDirectory;
      }
   }
   

2. In View's XAML:

   在View的XAML中:

   <TextBox Text="{Binding CurrentDirectoryPath}" />
   

3. Setup right DataContext

   设置权限DataContext

   // If you are using MVVM:
   var view = new MyView { DataContext = new MyViewModel() };

One solution is to create property in window (or some other parent container):

一种解决方案是在窗口(或其他一些父容器)中创建属性:

public string CurrentPath
{
    get
    {
        return Environment.CurrentDirectory;
    }
}

And bind in XAML like this:

并在XAML中绑定如下:

<TextBox Text="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Window}}, Path=CurrentPath, Mode=OneTime}" />

you could also do something like

你也可以做点什么

public string CurrentPath 
{     
    get     
    { 
        return AppDomain.CurrentDomain.BaseDirectory;     
    } 
}
