TakeWhile, TakeWhile, and linqtakewhile in Linq

TakeWhile, TakeWhile, and linqtakewhile in Linq

These two concepts are easy to confuse and understand. Then I will write them here to facilitate memory.

 

 

SkipWhile can be understood as if the condition is met, it will always skip and retrieve all the remaining elements after knowing that the condition is not met (the remaining elements will not be judged)

TakeWhile can be understood as if the condition is met, the value is always valid until it is not met and all the remaining elements are lost (the latter will not be judged)

 

Int [] intAry = {2, 4, 5, 8, 9, 11, 10, 20, 15, 45, 78, 80}; var query = intAry. takeWhile (num => num % 2 = 0); var query1 = intAry. skipWhile (num => num % 2 = 0); // query: 2 4 // query1: 5, 8, 9, 11, 10, 20, 15, 45, 78, 80
