Question

I have deployed successfully a C# windows service on a windows 7 machine.

Now, when I try to create a file using this code :

  FileStream os = new FileStream(String.Format(folderName, fileName), FileMode.Create);

I get Access to filepath is denied.

In the service Installer I set the following parameters to :

   this.serviceProcessInstaller1.Account = 
       System.ServiceProcess.ServiceAccount.LocalSystem;
   this.serviceProcessInstaller1.Password = "Pass";
   this.serviceProcessInstaller1.Username = "Administrator"

I added all the possible accounts with Full permissions to the folder where I want to create the file but nothing helped.

Any suggestions would be highly appreciated

You’re using String.Format() in the wrong way. Look at msdn http://msdn.microsoft.com/en-us/library/fht0f5be.aspx.

You probably want something like

FileStream os = new FileStream(folderName  +@"\" + fileName, FileMode.Create);

or

FileStream os = new FileStream(String.Format(@"{0}\{1}", folderName fileName), FileMode.Create);

or

FileStream os = new FileStream(Path.Combine(folderName fileName), FileMode.Create);
