SharePoint: PortalContext – gives “Value cannot be null. Parameter name: site”


I came across the following problem in PortalContext API.


 


Say I have created a portal with port number 9091. I am using the following code snippet to retrieve the portal context.


 


[working though we changed the port number]


TopologyManager tm = new TopologyManager();


PortalSite ps = tm.PortalSites[ new Uri[http://karthickmain:9091)];


PortalContext ctx = PortalApplication.GetContext(ps);


 


The code works fine no problem. For some reason, I have changed the port number to 9092. Now I have modified the code by changing the port number.


 


[not working] 


TopologyManager tm = new TopologyManager();


PortalSite ps = tm.PortalSites[ new Uri[http://karthickmain:9092)];


PortalContext ctx = PortalApplication.GetContext(ps);


 


The code doesn’t work. Its giving the following error. “Value cannot be null. Parameter name: site”


 


But if I use the same port number 9091 and execute the earlier code, its working fine. Because of this issue, getting the portal context by hardcoding the portal url is not advisable.

    Hi Karthikeyan,

    I too face with issue similar to this.

    PortalSite ps = tm.PortalSites[ new Uri( virtualServerUrl ) ];

    ctx =Microsoft.SharePoint.Portal.PortalApplication.GetContext(ps);

    It seems that this has something to do with SharePoint is not running in port 80. Were you able to find a workaround for this?
