如何从linq获取int值(How to get the int value form the linq)

我该如何解决以下问题：

var xvalue = from cust in list where cust.DisplayString == ((Data)x).CustomerName select cust.Number; int namX = xvalue;

How can I resolve the issue below:

var xvalue = from cust in list where cust.DisplayString == ((Data)x).CustomerName select cust.Number; int namX = xvalue;

最满意答案

您的查询将始终返回匹配结果的“集合”，即使集合仅返回单个项目。

如果您知道查询将始终只匹配单个项目，则可以使用Single Linq方法：

var xvalue = from cust in list where cust.DisplayString == ((Data)x).CustomerName select cust.Number; int namX = xvalue.Single();

Your query will always return a 'collection' of matching results, even if the collection returns just a single item.

If you know that your query will always match just a single item, you can use the Single Linq method:

var xvalue = from cust in list where cust.DisplayString == ((Data)x).CustomerName select cust.Number; int namX = xvalue.Single();
