尝试查看xml文件的路径时访问被拒绝

Question

I am trying to get the path for an xml file i created in my lightswitch application. however i am getting System.Security.SecurityException error saying access is denied.

var fileNme = Path.Combine(
    Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData),
    "Sample.xml");
Debug.WriteLine("app data path " + fileNme.ToString());

I am running the application locally on my computer and the eventually deploy to iis. Hopefully someone solution can help me out here.
Thank you.

I am not an expert in LightSwitch, but you can try this:

Assembly asm = Assembly.GetAssembly(typeof(<<assemblyNamespace>>.<<name_of_page_class>>));
string asmPath = asm.CodeBase;

string app_DataFolder = Path.GetFullPath(Path.GetDirectoryName(asmPath.Remove(0, "file:\\\\\\".Length)) + "\\..\\App_Data");

string filePath = Path.Combine(app_DataFolder, "Sample.xml");

Hope it helps!
