LINQ to XML返回一个对象而不是IEnumerable <object>

Question

我有这个代码:

   MyObject Obj {get;set;}
    var x = from xml in xmlDocument.Descendants("Master")
        select new MyObject
        {
            PropOne = //code to get data from xml
            PropTwo = //code to get data from xml
        }

其结果是var是IEnumerable<MyObject>,我需要使用foreach循环分配x到Obj:

foreach(var i in x)
{
    Obj = i;
}

有没有办法可以使用LINQ语句而没有IEnumerable以这种方式返回？或者foreach像我一样使用循环是否正常？

是的:

Obj = (from xml in xmlDocument.Descendants("Master")
        select new MyObject
        {
            PropOne = //code to get data from xml
            PropTwo = //code to get data from xml
        }).FirstOrDefault();
