how to get a linq query result to int

Question

below query return a single value eg 50. I want it be assign to int so I can do some calculation with that value. how can I do this

var LTLimit = from a in dbavailability.tACLicenseTypes
                  where a.License_Type == "Long Term"
                  select a.Limit;



    string AST = "";

Answer 1

I'm not completely clear on what you're asking, but presumably the type of data returned by your Linq query is not int , and you want to convert it to int? If so, simply convert it to an int:

var LTLimit = (from a in dbavailability.tACLicenseTypes
                  where a.License_Type == "Long Term"
                  select a.Limit).ToList();

int LTLimitInt = 0
if (!int.TryParse(LTLimit.First(), out LTLimitInt))
{
    Console.WritLine("LTLimit is not a number!")
}

Since you've updated your question, here's a solution to convert the returned number to an int, multiply it by 2, then convert the result to a string:

var LTLimit = (from a in dbavailability.tACLicenseTypes
                  where a.License_Type == "Long Term"
                  select a.Limit).ToList();

int LTLimitInt = 0;
string multipliedResultStr = string.Empty;
if (!int.TryParse(LTLimit.First(), out LTLimitInt))
{
    Console.WritLine("LTLimit is not a number!")
}
else 
{
    multipliedResult = (LTLimitInt * 2).ToString();
    Console.WriteLine(string.Format("Result is {0}, multipliedResult ));
}

Edit;

Corrected code to take first item from list.

Answer 2

What is the return type of the query? If the returned type is of another primative data type like a string, then you can try to convert it to an integer using :

var i = Convert.ToInt32(LTLimit);

Or using :

int.TryParse(LTLimit, out var i);

However, it would be better if the data was stored in the correct type in the first place.

Answer 3

The following code is one way to retrieve the first integer returned in your query:

var LTLimit = (from a in dbavailability.tACLicenseTypes
              where a.License_Type == "Long Term"
              select a.Limit).ToList();

int limit = LTLimit[0];

You can use Sum() after where() for value of object property

like this bonus.Where(b => b.Id == x.key && b.RequiredScore.HasValue).Sum(b => b.RequiredScore.Value);
