[MOSS 2007] 解决Web Service之Operation is not valid due to the current state of the object.

摘要:[MOSS 2007] 解决Operation is not valid due to the current state of the object.

Description: When writing a Web Service, use to produce news SPSecurity.RunWithElevatedPrivileges

solve:

The original

SPSecurity.RunWithElevatedPrivileges(delegate()
{
    using (SPSite site = new SPSite("http://SiteUrl"))
    {
        using (SPWeb web = site.OpenWeb())
        {
            ......
        }
    }
 });

Changed

SPWeb web = null;
SPSecurity.RunWithElevatedPrivileges(delegate()
{
    using (SPSite site = new SPSite("http://SiteUrl"))
    {
        web = site.OpenWeb();
        ......
    }
});
web.Dispose();

That is, SPWeb independent, not on the inside SPSecurity.RunWithElevatedPrivileges
