Linq Quantifiers
suggest changeQuantifier operations return a Boolean value if some or all of the elements in a sequence satisfy a condition. In this article, we will see some common LINQ to Objects scenarios where we can use these operators. There are 3 Quantifiers operations that can be used in LINQ:
All
– used to determine whether all the elements in a sequence satisfy a condition. Eg:
int[] array = { 10, 20, 30 };
// Are all elements >= 10? YES
array.All(element => element >= 10);
// Are all elements >= 20? NO
array.All(element => element >= 20);
// Are all elements < 40? YES
array.All(element => element < 40);
Any
- used to determine whether any elements in a sequence satisfy a condition. Eg:
int[] query=new int[] { 2, 3, 4 }
query.Any (n => n == 3);
Contains
- used to determine whether a sequence contains a specified element. Eg:
//for int array
int[] query =new int[] { 1,2,3 };
query.Contains(1);
//for string array
string[] query={"Tom","grey"};
query.Contains("Tom");
//for a string
var stringValue="hello";
stringValue.Contains("h");
