使用sharepoint的CAML查询，有的时候需要设置范围，这时候只需要设置SPQuery的ViewAttributes属性即可

下面是SPQuery.ViewAttributes的值：

queryDefault.ViewAttributes = "Scope='Default'";            queryFilesOnly.ViewAttributes = "Scope='FilesOnly'";            queryRecursive.ViewAttributes = "Scope='Recursive'";            queryRecursiveAll.ViewAttributes = "Scope='RecursiveAll'"; 具体可以参考一下文档：
