app data - Getting Access denied trying to read a file in App_Data in a ASP.NET project - Any pointers? -

-

I have an XMD file that is stored in App_Data which is used only to read some configurations on startup When I try to open it within my code, I get access to the path ... the message has been denied.

Why I am having trouble understanding, and how to solve it, I think in theory that I should change the permissions on the file (and directory), but nothing has changed it.

To give a bit more background: 1. One of its projects is bundled with the project, so setup made by VS2008 wrote it in the right place during installation. I did not think I would need to install an unusual post, such as the ASP.NET application would be used. 2. When I tried to publish it locally, I had no problem. - It's only on a test Windows 2003 server. I have run a simple page to understand the effective user of IIS - this is NT AUTHORITY \ NETWORK service. I tried to give this user "full access" to this file , And even then it does not work

The code is simple to open it: 

  FileStream fs = new filestream (server.mappath, filemod.open);

Whereas S ~ ~ / App_Data / myfile.xml is defined as

I have also copied and pasted the full path & amp; File name (with exception) and tried to "dir" on it, and it actually exists (for example, around a typo).

Actually, I think I got it. I need to open the file as follows:

New file stream (Server.mappath (files), File MOD. Open, FileAccess. Read);

c# - TypeConverter in propertygrid only converts from string, not to -

-
When the property grid is reached, only the conversion mechanism (often called) is called "Foo!" Returns the property string in the grid when I click to edit I get an exception Type.oo. Object type can not be changed to type. (Not properly translated,) What is a clue from the convert format, why not? And the error indicates that it is trying to convert to a string, not from. I think that when I want to edit this object, it will have to be converted from foo to string, and when the editing ends. Public class FooTypeConverter: StringConverter {public override object ConvertFrom (ITypeDescriptorContext Reference, CultureInfo Culture, Object Value) {New Foo (string) value); } Convert the public override object (Type the ITE DiskText Contact Reference, CultureInfo Culture, Object Value, Type Type) {Return "Foo!"; } Public override bool CanConvertFrom (ITypeDescriptorContext reference, type source type) {back true; } Public Override Bull CanConvertTo (ITypeDescrip...
