设置其查询属性时，请抛出异常

Question

我正在查询SharePoint网站中的多个任务列表。我可以检索结果，直到设置查询属性并指定订单子句。详细的异常和代码在下面粘贴。感谢任何帮助

private void doTasks(SPWeb currentWeb, SPSiteDataQuery q)
    {

    q.Query =
         "<OrderBy>" +
         "   <FieldRef Name='Priority' />" +
         "   <FieldRef Name='DueDate' />" +
         "</OrderBy>";

    // Specify the view fields.
    q.ViewFields = "<FieldRef Name='Title' Type='Text'/>";
    q.ViewFields += "<FieldRef Name='AssignedTo' Type='User' Nullable='TRUE' />";
    q.ViewFields += "<FieldRef Name='PercentComplete' Type='Number' Nullable='TRUE'/>";
    results = currentWeb.GetSiteData(q);

    if (results.Rows.Count > 0)
    {
             //blah!
    }
}

Answer 1

在迁移期间，某些页面布局使用SPSITEDAQUERY来查询跨不同网的内容类型以获取内容。该代码在SP2007中运行良好，但在SP2010中，它引发了例外，如下所述：

解决方案

确保您使用该订单的字段包含在spsitedataquery.viewfields属性中。就如此容易！
