Lambda expressions and LINQ statements are both tools in C# for querying and filtering data, but they have some similarities and differences.
Different score:
1. The syntax is different: Lambda expressions are an anonymous function that can be used to create delegates or expression trees. The LINQ statement is a query statement that uses specific keywords and syntax to query data.
2. Different functions: Lambda expressions can be used in any occasion that requires delegation or expression trees, while LINQ statements can only be used to query and filter data.
3. Different query methods: Lambda expressions query data through method chain calls, while LINQ statements query data through a SQL-like syntax.
Concrete syntax:
The syntax of Lambda expressions:
(parameter_list) => expression
For example:
(int x, int y) => x + y
The syntax of the LINQ statement:
from variable in collection
where condition
select variable
For example:
var result = from student in students
where student.Age > 18
select student;
