我使用一个组件(System.ComponentModel.Component),我想获取我的项目的应用程序路径,以便在其中创建一个文件。
谢谢

对于我来说唯一似乎起作用(始终如一)的是获取EnvDTE.DTE(从EditValue()中获取的IServiceProvider),即:
EnvDTE.DTE dte = envProvider.GetService(typeof(EnvDTE.DTE)) as EnvDTE.DTE;
string dir = Path.GetDirectoryName(dte.Solution.FullName);
string GetMyPath([CallerFilePath] string from = null)
{
return from;
}
string solutionpath = Directory.GetParent(Application.ExecutablePath).Parent.Parent.Parent.FullName;
我认为这是最好的解决方案,因为你不需要添加任何库,只需使用 "Using System.IO" :)
public class DesignAdorner : PrimarySelectionAdornerProvider
{
protected override void Activate(ModelItem item)
{
modelItem = item;
}
}
string aplicationPathDir = System.IO.Directory.GetParent(modelItem.Context.ToString()).FullName;
如果这不能帮到你,请告诉我。
这个可以工作吗?
New Uri(Assembly.GetCallingAssembly().CodeBase).AbsolutePath
("CallingAssembly" 是因为你可以将检索执行路径的方法放入服务层(程序集)中)
我认为罗伯特几乎是对的。
这似乎有效:
Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location)
在.NetFrameWork 4.5程序集中添加对envdte80的引用。
DTE2 dte = DesignTimeProjectPath.Processes.GetDTE();
if (dte != null)
{
var solution = dte.Solution;
if (solution != null)
{
string baseDir = Path.GetDirectoryName(solution.FullName);
MessageBox.Show(baseDir);
}
}

我进行了一个简单的测试(只是作为临时设计,我添加了一个字符串属性来保存当前目录值)(我没有描述数据绑定的整个过程。请参阅我的一些关于设计时/运行时绑定的帖子)
在主窗口ViewModel类的空构造函数中(专门用于设计时绑定)
public MainWindow_ViewModel():this(null)
{
dtpath = Directory.GetCurrentDirectory();
Console.WriteLine("CTor finished");
}
<TextBox Text="{Binding dtpath}" Grid.Row="3"/>
我进入了VS的设计视图(就像Florian的评论所说,但是在4年后有一个更新的值): C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE
