[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.

说明：在写Web Service的时候，使用到了SPSecurity.RunWithElevatedPrivileges而产生的消息

解决：

将原本

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

改为

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

也就是将SPWeb独立出来，不要放在SPSecurity.RunWithElevatedPrivileges里面
