Question

我有这种情况，我需要选择Bar对象Val大于0，同时保持对象的当前月份Val是0还是大于0。 / p>

var currentMonth = new DateTime(2015, 3, 1); // Just an example
var foo = new List<Bar>()
{
  new Bar { Date = '01/01/2015', Val = 40 },
  new Bar { Date = '02/01/2025', Val = 30 },
  new Bar { Date = '03/01/2015', Val = 0 },
  new Bar { Date = '04/01/2015', Val = 2 },
  new Bar { Date = '05/01/2015', Val = 5 }
}

// I also need to select the current month whether it's Val is 0 or greater than 0
// Stuck here
var fooResult = foo.Where(f => f.Val > 0);

所以结果应该是这样的：

{
  new Bar = { Date = '03/01/2015', Val = 0 },
  new Bar = { Date = '04/01/2015', Val = 2 },
  new Bar = { Date = '05/01/2015', Val = 5 }
}

或者，如果将currentMonth声明为此。 var currentMonth = new DateTime(2015, 4, 1);

结果应该是这样的：

{
  new Bar { Date = '04/01/2015', Val = 2 },
  new Bar { Date = '05/01/2015', Val = 5 }
}

非常感谢任何帮助。感谢

试试这个

var fooResult = foo.Where(f => f.Val > 0 || currentMonth.Month ==Convert.ToDateTime(f.Date).Month);

查询值大于0的集合，同时保持当前月份值是0还是大于0
