Question

I am using c#.net

I have two textboxes which if !empty need to be part of a WHERE clause within a LINQ query.

Here is my code

var result = from a in xxxx select a;

if(!string.IsNullOrEmpty(personName))
{
    return result.Where(a >= a.forename.Contains(personName) || a.surname.Contains(personName)     
}
else if(!string.IsNullOrEmpty(dateFrom))
{
    return result.Where(a >= a.appStartDateTime >= dateFrom.Date)
}
else if(!string.IsNullOrEmpty(personName) && !string.IsNullOrEmpty(dateFrom))
{
    return result.Where(a >= a.forename.Contains(personName) || a.surname.Contains(personName) &&   a.appStartDateTime >= dateFrom.Date);
}

I thought this would work but it doesn’t like the .Where and I cant access the ‘a’ for example a.forename (The name ‘a’ does not exist in the current context)

What am I going wrong, or can this not actually be done?

Thanks in advance for any help.

Answer 1

Instead of this:

result.Where(a.forename.Contains(personName))

Try this:

result.Where(a => a.forename.Contains(personName))

You appear to be missing the Lambda operator (=>).
