使用流检查List<String>是否包含List<Object>中的所有元素 如何检查List<string>是否存在其他List<string>中的所有值 如何正确使用LINQ Query on List<KeyValuePair<string,string>来创建Dictionary<KeyValuePair<string,string>,int>? terraform中的Concat字符串
WriteLine("差集:"); foreach (var item in difference) { Console.WriteLine(item); } } } 上述代码中,我们首先创建了两个整数类型的列表list1和list2,然后使用Linq的Intersect、Union和Except方法来比较这两个列表的交集、并集和差集。最后,我们通过循环打印出比较结果。 使用Linq比较两个通用列表的优势在于简洁...

延迟执行特性:查询语句构造完成后, 并不会立即执行,而是等到foreach里面才执行,在这执行之前,如果新增了元素,那么元素在foreach里也或生效。 临时使用外部变量:当foreach前改变lambda表达式里面的外部变量值,那么构造的语句也会根据外部变量改变而改变 //延迟执行特性List<int>list=newList<int>{1};IEnumerable<int>...
