DoesUserHavePermissions

Here is the best way to evaluate if a user can view a list. I had many problems with a web part and after investigations, this method resolve the problems.

Read the comments in the code to learn more about it!

Code:

	public bool UserCanViewListItems(SPWeb web, SPList list)
	{
	bool res = true;
	SPWeb myweb = null;
	SPSite mysite = null;
	try
	{
	/* There is a kind of ownership problem related to the DoesUserHavePermissions.
	* To fix that problem, the user performing the execution of the method, needs to
	* be the same as the one who created the Parent Object. For this reason, This
	* Method use the List object received in param and recreate the Parent object to
	* get the ownership. And it works perfectly.*/
	mysite = new SPSite(list.ParentWeb.Url);
	myweb = mysite.OpenWeb();
	list = myweb.Lists[list.Title];
	list.Permissions.DoesUserHavePermissions(SPRights.ViewListItems);
	}
	catch(Exception)
	{
	res = false;
	}
	finally
	{
	if(myweb!=null)
	myweb.Dispose();
	if(mysite!=null)
	mysite.Dispose();
	}
	return res;
	}
