I'm unable to find a recent decent answer on this.
Linq does not support regex, and trying to extract a method out does not outsmart the framwork. How do I do a whole work match on a list of sentences in linq.
The reason I need the \\b is because it could be start or end of string, or have a comma, dash, or other similar separators.
private bool isMatch(string searchText, string text)
{
return Regex.IsMatch(searchText, "\\b"+text+"\\b", RegexOptions.IgnoreCase | RegexOptions.Compiled);
}
result p = itemsRep
.Where(fullText=> isMatch(searchText, fullText))
.FirstOrDefault();
I think what you're saying is that Linq-to-SQL/Linq-To-Entities does not support Regex
in expressions.
Try adding .AsEnumerable()
before your .Where()
.
The .Where()
method will then enumerate over the results of any translated query, rather than try to convert your .Where()
expression to SQL.
Like this:
result p = itemsRep
.AsEnumerable()
.Where(fullText => isMatch(searchText, fullText))
.FirstOrDefault();
