Question

如果在引用的dll中使用Application.StartupPath，则该路径指向IDE的路径。

无论如何都要获得实际应用的路径？

为了清楚起见，这是在设计时。

ETA：我发布了以下解决方案：

ETA2：

因为它是相关的，我想我会发布另一个有用的设计时服务的片段。与下面的解决方案类似，此示例适用于UITypeEditor：

Public Overrides Function EditValue(ByVal context As System.ComponentModel.ITypeDescriptorContext, ByVal provider As System.IServiceProvider, ByVal value As Object) As Object

    Dim typeDiscovery As ITypeDiscoveryService = TryCast(provider.GetService(GetType(ITypeDiscoveryService)), ITypeDiscoveryService)
    Dim types As ICollection = typeDiscovery.GetTypes(GetType(MyType), False)

End Function

类型将包含从MyType派生的所有类型。将第二个参数更改为True以排除搜索GAC。将Nothing作为获取所有类型列表的第一个参数。

Answer 2

以下是如何从UITypeEditor中执行此操作。

ETA：原始代码有一个额外不需要的步骤。我忘了我们有一个serviceprovider，所以不需要查看该网站。简化的代码是：

Public Class MyEditor
    Inherits UITypeEditor

    Public Overrides Function EditValue(ByVal context As System.ComponentModel.ITypeDescriptorContext, ByVal provider As System.IServiceProvider, ByVal value As Object) As Object

        Dim typeRes As ITypeResolutionService = TryCast(provider.GetService(GetType(ITypeResolutionService)), ITypeResolutionService)
        Dim ass As System.Reflection.AssemblyName = System.Reflection.Assembly.GetExecutingAssembly().GetName()
        MessageBox.Show(ass.CodeBase, "Design-time Path")
        MessageBox.Show(typeRes.GetPathOfAssembly(ass), "Run-time Path")

    End Function

End Class

原始代码：

Public Class MyEditor
    Inherits UITypeEditor

    Public Overrides Function EditValue(ByVal context As System.ComponentModel.ITypeDescriptorContext, ByVal provider As System.IServiceProvider, ByVal value As Object) As Object

        Dim component As IComponent = TryCast(context.Instance, IComponent)
        Dim site As ISite = component.Site
        Dim typeRes As ITypeResolutionService = TryCast(site.GetService(GetType(ITypeResolutionService)), ITypeResolutionService)
        Dim ass As System.Reflection.AssemblyName = System.Reflection.Assembly.GetExecutingAssembly().GetName()
        MessageBox.Show(ass.CodeBase, "Design-time Path")
        MessageBox.Show(typeRes.GetPathOfAssembly(ass), "Run-time Path")

    End Function

End Class

此解决方案基于How to: Access Design-Time Services的代码，您可以在其中找到大量信息。

你不能在设计时做到这一点！在运行时，您可以，也就是说，在构建应用程序并运行它，或在VS中点击F5或单击绿色箭头时。你为什么要在设计时知道？这是无关紧要的，因为可执行文件及其相关的DLL并没有真正加载到内存中并执行，而且，如果对代码进行了更改，则必须重新构建整个项目。

希望这有帮助，最好的祝福，汤姆。
