EXISTING ERRORS :

// using (SPWeb oWebsite = oSiteCollection.AllWebs["http://sks-blr-sp02:46346"])

Solution:

You could use the following options to get the SPweb object:

Option 1:

SPSite mysitecollection = new SPSite("http://bhaskar-4o6b0zz:406");
SPWeb site = mysitecollection.AllWebs["Cricket"]; (if Cricket is the name of the web)

Option 2:

SPSite mysitecollection = new SPSite("http://bhaskar-4o6b0zz:406/sites/Cricket");
SPWeb site = mysitecollection.OpenWeb();

// spuser.Update();

Solution:

spWeb.AllowUnsafeUpdates = true;
