c# - Difference between && and where condition in entity framework query

Question

Difference between and condition and two where condition in entity framework query

Code 1

I have using two where condition in my query

 dbContext.Projects.Where(p=>p.ProjectId!=ProjectId).Where(p=>p.Name==Name)
 .SingleOrDefault();

---

code 2

I have using && condition without using two where condition

  dbContext.Projects.Where(p=>p.ProjectId!=ProjectId &&  
  p.Name==Name).SingleOrDefault();

---

• What is the difference between code1 and code2????

The both queries are return same value. but i don't know the differences. Please explain to me, which one is better. and why?

Answer 1

If you open your query in LinqPad you will see that both queries

dbContext.Projects.Where(p=>p.ProjectId!=ProjectId).Where(p=>p.Name==Name)

dbContext.Projects.Where(p=>p.ProjectId!=ProjectId && p.Name==Name);

will result both in

SELECT [...]
FROM [...]
WHERE p.ProjectId <> someId AND p.Name = 'something'

There is no difference neither in performance nor in SQL query structure.
