working with xml in App_data folder

Question

Hi,

I have .xml file in App_data folder and app is hosted in Azure. When I work with content of this file I get this error:

Could not find a part of the path 'E:\sitesroot\0\App_Data\Options.xml'.

here is the .aspx.cs example:

XDocument doc = XDocument.Load(Server.MapPath("~/App_Data/Options.xml"));
                if (doc.XPathSelectElement("Options/MemberCode").FirstAttribute.Value == "true")
                {
                    TextBoxMemberCode.Enabled = true;
                }

In IIS and localhost it works perfectly but I know that Azure is something different...

How can I solve this trouble ??

Answer 1

Hi,

Just a quick check,

In the properties of the Options.xml, Have you enabled "Copylocal=true"?

Answer 5

Hi,

I'd like to suggest you use Remote Desktop to connect Azure VM and see that XML file is existing. As far as i know, azure package is deployed it's not creating the /App_Data/ folder, you can check for this.

And i dont think this is a good way to put xml file in app root directory:

1, security reason. it's not a good practice that the worker account has write access to the app directory.

2, recycling reson. when a certain amount of files (or directories) change or get created, IIS might decide to recycle the app domain.

The better solution is local storage, try this:

Service definition:

<LocalResources>
      <LocalStorage name="cacheStorage" sizeInMB="20480" cleanOnRoleRecycle="false" />
</LocalResources>

Code:

string cachePath = RoleEnvironment.GetLocalResource("cacheStorage").RootPath;
string filePath = Path.Combine(cachePath, filename); 

Hope this helps.
