Error getting too many character literals - linq

Question

var query = from s in bv.baParticularHeaders
from v in bv.baPlanColumnStructures
where x.Contains(s.Particular_Num)
select new LevelList
{
Value = 'Level ' + LTRIM(Rtrim(Convert(Char,P.Level_Num))) + ' - ',
id = 'Column ' + LTRIM(Rtrim(Convert(Char,P.Column_Num))) + ' ',
Text = v.Column_Description
};
return query.Distinct().OrderBy(o => o.Value).AsQueryable<LevelList>();
Error getting this both lines of code.
Value = 'Level ' + LTRIM(Rtrim(Convert(Char,P.Level_Num))) + ' - ',
id = 'Column ' + LTRIM(Rtrim(Convert(Char,P.Column_Num))) + ' ',
Can any body help me out how to convert this in LINQ?
Thanks

You can't just cut and paste SQL, rearrange it and hope to get a valid LINQ query. The aim is to write the appropriate C# code, which is translated into SQL. In this case I suspect you want:
var query = from s in bv.baParticularHeaders
from v in bv.baPlanColumnStructures
where x.Contains(s.Particular_Num)
select new LevelList
{
Value = "Level " + P.Level_Num + " - ";
id = "Column " + p.Column_Num + " ",
Text = v.Column_Description
};
return query.Distinct().OrderBy(o => o.Value).AsQueryable();
Note the string literals - "Level " not 'Level '. The code has to be valid C# first.
(Assuming Level_Num and Column_Num are numbers, I can't see why it would make sense to trim them.)
