在Visual Studio 2010(和.Net 4)中的node.js本机插件中,我可以使用
System::Reflection::Assembly::GetExecutingAssembly()->Location
获取正在运行的C ++ / CLI程序集的路径,但在Visual Studio 2015项目(和.Net 4.6)中的node.js插件中,我得到一个例外:
System.ArgumentException: Illegal characters in path.
at System.IO.Path.CheckInvalidPathChars(String path, Boolean checkAdditional)
at System.Security.Permissions.FileIOPermission.CheckIllegalCharacters(
String[] str)
at System.Security.Permissions.FileIOPermission.AddPathList(
FileIOPermissionAccess access, AccessControlActions control,
String[] pathListOrig, Boolean checkForDuplicates,
Boolean needFullPath, Boolean copyPathList)
at System.Security.Permissions.FileIOPermission..ctor(
FileIOPermissionAccess access, String path)
at System.Reflection.RuntimeAssembly.get_Location()
知道如何获取正在运行的程序集的路径吗?
编辑2018-01-25 Visual Studio 2017仍未解决此问题,这次尝试使用.Net 4.5.2
答案 0 :(得分:0)
尽管会抛出Location
属性,但仍可以使用CodeBase
,它返回的内容如下:
file://?/C:/.../my-addon.node
这将解释非法字符:“?”
一个new Uri(Application.CodeBase).LocalPath
将返回
/?/C:/.../my-addon.node
因此,GetExecutingAssembly()->Location
的解决方法可能是:
String^ GetExecutingAssemblyLocation()
{
try
{
return Path::GetDirectoryName(Assembly::GetExecutingAssembly()->Location);
}
catch (Exception^ e)
{
String^ codeBase = Assembly::GetExecutingAssembly()->CodeBase;
if (codeBase->StartsWith("file://?/"))
{
Uri^ codeBaseUri = gcnew Uri("file://" + codeBase->Substring(8));
return codeBaseUri->LocalPath;
}
else
throw;
}
}
这将返回
C:\...\my-addon.node
