问题描述
如果我使用扩展方法语法,以下查询将如何显示?
How would the following query look if I was using the extension method syntax?
var query = from c in checks
group c by string.Format("{0} - {1}", c.CustomerId, c.CustomerName)
into customerGroups
select new { Customer = customerGroups.Key, Payments = customerGroups }
推荐答案
它看起来像这样:
var query = checks
.GroupBy(c => string.Format("{0} - {1}", c.CustomerId, c.CustomerName))
.Select (g => new { Customer = g.Key, Payments = g });
