linq-to-xml - 如何在 LINQ to XML 中指定顶部行数？

Question

在 LINQ to SQL 中，我可以说 var ......Take(50); 现在我有了这个 LINQ2XML 代码：

                    XElement xml = new XElement("Materials",
                    from material in _db.MTIs
                    where material.MTName.ToString().Contains(comparer)
                    select new XElement("Material",
                              new XElement("MTID", material.MTID),
                              new XElement("MTName", material.MTName),
                              new XElement("ComputerNO", material.ComputerNO),
                              new XElement("ModelNO", material.ModelNO),
                              new XElement("Whole", material.Whole)));

我只想获得前 50 行匹配结果，我怎么能执行这样的事情？

谢谢。

                XElement xml = new XElement("Materials",
                _db.MTIs.Where(material => material.MTName.ToString().Contains(comparer))
                .Take(50)
                .Select(material =>
                    new XElement("Material",
                          new XElement("MTID", material.MTID),
                          new XElement("MTName", material.MTName),
                          new XElement("ComputerNO", material.ComputerNO),
                          new XElement("ModelNO", material.ModelNO),
                          new XElement("Whole", material.Whole))));
