I am trying to use Linq2Sql to return all rows that contain values from a list of strings. The linq2sql class object has a string property that contains words separated by spaces.
public class MyObject
{
public string MyProperty { get; set; }
}
Example MyProperty values are:
MyObject1.MyProperty = "text1 text2 text3 text4"
MyObject2.MyProperty = "text2"
For example, using a string collection, I pass the below list
var list = new List<>() { "text2", "text4" }
This would return both items in my example above as they both contain "text2" value.
I attempted the following using the below code however, because of my extension method the Linq2Sql cannot be evaluated.
public static IQueryable<MyObject> WithProperty(this IQueryable<MyProperty> qry,
IList<string> p)
{
return from t in qry
where t.MyProperty.Contains(p, ' ')
select t;
}
I also wrote an extension method
public static bool Contains(this string str, IList<string> list, char seperator)
{
if (String.IsNullOrEmpty(str) || list == null)
return false;
var splitStr = str.Split(new char[] { seperator },
StringSplitOptions.RemoveEmptyEntries);
foreach (string s in splitStr)
foreach (string l in list)
if (String.Compare(s, l, true) == 0)
return true;
return false;
}
Any help or ideas on how I could achieve this?
