.net – FileNotFoundException with the SPSite constructor

netSecuritysharepointsharepoint-2007sharepoint-2010

I try to instantiate an instance of SPSite on the farm server in a custom process (MyApp.exe) and I give it as parameter the whole URI (http://mysite:80/). I also made sure that the account running MyApp.exe is Site Collection Administrator.

However, I can't make an instance of SPSite whatever I am trying to do. It always throws a FileNotFoundException.

Anyone got an idea?

StackTrace:

at
Microsoft.SharePoint.SPSite..ctor(SPFarm
farm, Uri requestUri, Boolean
contextSite, SPUserToken userToken)
at
Microsoft.SharePoint.SPSite..ctor(String
requestUrl) at
MyCompanyName.Service.HelperClass.GetItemStateInSharePoint(SharePointItem
item) in
C:\Workspaces\MyCompanyName\Development\Main\MyCompanyName.SharePoint\Service\HelperClass.cs:line
555

Another side note… I have a Web Application + Site collection that I can access through the browser without any problem.

The FileNotFoundException is thrown by SharePoint when it cannot find the requested site collection in the SharePoint configuration database. My guess is that you have not yet created a site collection on the URL http://mysite:80. I see the following stack trace if I try and instantiate a new SPSite object with the URL of a non-existing site collection:

System.IO.FileNotFoundException : The site http://server/sites/bah could not be found in the Web application SPWebApplication 
Name=SharePoint - 80 Parent=SPWebService.
at Microsoft.SharePoint.SPSite..ctor(SPFarm farm, Uri requestUri, Boolean contextSite, SPUserToken userToken)
at Microsoft.SharePoint.SPSite..ctor(String requestUrl)

Specify the proper URL of your site collection or open Central Administration and create a new Site Collection.

This is the style that Microsoft tends to use in their examples.

It appears that the guidance in this area may have changed, as StyleCop now enforces the use of the C# specific aliases.

C# – Calling the base constructor in C#

Modify your constructor to the following so that it calls the base class constructor properly:

public class MyExceptionClass : Exception
{
    public MyExceptionClass(string message, string extrainfo) : base(message)
    {
        //other stuff here
    }
}

Note that a constructor is not something that you can call anytime within a method. That's the reason you're getting errors in your call in the constructor body.
