[英]C# test if list is empty()
How to do it? 怎么做?
Is it list.Count == 0? 它是list.Count == 0吗?
Thanks 谢谢
I think you meant ( Count
is a property, not a method): 我想你的意思是(
Count
是一个属性,而不是一个方法):
list.Count == 0
And the answer is yes. 答案是肯定的。 Microsoft documentation explicitly says: "Retrieving the value of this property is an O(1) operation."
Microsoft文档明确指出:“检索此属性的值是O(1)操作。”
