I just need it to check if the variable "remaining" equals 0
To check equality in C# use == operator.
if(remaining == 0){
// write your logic
}
Use the == operator
if(remaining == 0){
// write your logic
}
The == operator checks whether the LHS = RHS or not whereas
= is an assignment operator it is used to assign values like int a = 10;

I have this linq query in my controller and it is working fine,
var Engineers = dbcontext.Employees.Where(i => i.Department == "Engineers");
but I would like to add a second condition to the query to filter out the results,
var Engineers = dbcontext.Employees.Where(i => i.Department == "Engineers" && i.UserStatus = 1);
Thanks for your help.
You made a typo, just need to use comparison operator (==) instead of assignation (=)
So it would be like that:
var Engineers = dbcontext.Employees.Where(i => i.Department == "Engineers" && i.UserStatus == 1);

I am trying to check to see if this object contains any letters besides Z and if it does it should return Null. The way I have it initialized gives me no errors but when testing it does not actually return null if a letter is present.
if(request.DoorTag.Contains(#"[a - yA - Y]"))
{
return null;
}
if(Regex.IsMatch(request.DoorTag, "[a-yA-Y]")
{
return null;
}
But "[^zZ]" would even be better, since it'll check that your DoorTag contains any other char than Z

I'm trying to write the following LINQ query...
string userSearch = textBoxSearchUserInput.Text;
//LINQ query for Member name search
var MemberNameSearch =
from member in context.Members
where String.Compare(userSearch, member.MemberLastName, true) = 0
select member;
But I'm getting the error message in the title.
What I'm trying to achieve, comparing two strings while ignoring the case
Thanks
where String.Compare(userSearch, member.MemberLastName, true) == 0
To compare you need to use ==
This would work
String.Equals(userSearch, member.MemberLastName, StringComparison.OrdinalIgnoreCase)
You should change it
where String.Compare(userSearch, member.MemberLastName, true) = 0
To
where String.Compare(userSearch, member.MemberLastName, true) == 0

Hey guys I've been getting this on some code I've been working on for school. Been googling it for hours but can't find anything, any help would be appreciated.
Code:
if (dogName = "" || lstDogBreeds.SelectedIndex = -1)
Error:
Operator '||' cannot be applied to operands of type 'string' and 'int'
= is assignment operator, == is equality operator.
You use = for setting variables, like int numberOfApples = 20;
And you use == for checking if two things are equal, like
if (numberOfApples == 20)
{
//do stuff
}
the operator to compare if equal is ==
if(dogName == "" || lstDogBreeds.SelectedIndex == -1)

How to check if a label is visible?This is not working...
if(labelFS.Visible = false)
{do sth}
else//labelFS.Visible = true
{do other}
solved
Use == to compare two values, not the assignment operator (a single =).
By using a single =, you're actually setting the value of labelFS.Visible to False, which hides it.
(There's also no need to type out true and false .)
if (labelFS.Visible)
// do something
else
// do something else
I'd suggest reading up on the difference. Here's a start...
Equality Operator (==)
Assignment Operator (=)
if(labelFS.Visible == false)
{do sth}
else//labelFS.Visible == true
{do other}
Use == instead of =
