ASP.NET MVC: How to search decimal value?

wish of those help you can use SqlFunctions.StringConvert. There is no overload for int so you need to cast to a double or a decimal. Your code ends up looking like this:
code :
var items = from c in contacts
            select new ListItem
            {
                Value = SqlFunctions.StringConvert((double)c.ContactId).Trim(),
                Text = c.Name
            };

I wish this help you I had a similar problem, so maybe this helps: I had to specify the type in the DbContext. In my case, the field in the database was of type Money, and the C# type for the models property was Decimal:
code :
modelBuilder.Entity<MyEntity>().Property(e => e.Value).HasColumnType("Money");
modelBuilder.Entity<MyEntity>().Property(e => e.Value)
            .HasColumnType("Decimal")
            .HasPrecision(18, 5);

Hope this helps This is just yet another Floating-Point value problem.
When comparing a decimal value with a string, they are compared as floating-point (real) numbers.
code :
mysql> SELECT '18015376320243458' = 18015376320243458;
        -> 1
mysql> SELECT '18015376320243459' = 18015376320243459;
        -> 0
mysql> SELECT '18015376320243459'+0.0;
        -> 1.8015376320243e+16

wish of those help I got this error when running in an jupyter notebook. I think the problem was that I was using %load_ext autoreload autoreload 2. Restarting my kernel and rerunning solved the problem.

wish of those help The error message is pretty clear, you are attempting to call a SQL function in an in-memory list. Change your code to this:
code :
if (!string.IsNullOrEmpty(keyword))
{
    incidentList = incidentList
        .Where(x => x.IncidentNumber.ToString().Contains(keyword.ToUpper())
                 || x.CreatedBy.ToUpper().Contains(keyword.ToUpper())
        .OrderBy(x => x.IncidentNumber)
        .ToList();
}

return View(incidentList);
