Hi All,

I am facing some problem while executing the query having 'Contains' keyword in Dynamic linq in C#. I am getting the below error

No property or field exists in type 'Int32'

My code is as below:

If I user the 'Contains' keyword for datatype string field, then it works fine as below

string[] CandidateNamesArray = new string[]{"Ram", "Venkat", "Micheal"}
var dynamicLinqQuery = Candidates.Where("CandidateName.Contains(@0)", CandidateNamesArray ); - works fine

But if I use the 'Contains' keyword for datatype int field, then it throws exception as below

int[] CandidateIdsArray = new int[]{4, 78, 101}
var dynamicLinqQuery = Candidates.Where("CandidateId.Contains(@0)", CandidateIdsArray);
Runtime Exception - "No applicable method 'Contains' exists in type 'Int32'"

Also tried in another way as below
int[] CandidateIdsArray = new int[]{4, 78, 101}
var dynamicLinqQuery = Candidates.Where("@0.Contains(CandidateId)", CandidateIdsArray);
Runtime Exception - "No property or field 'CandidateId' exists in type 'Int32'"

I have spend almost 2 days to resolve the above problem but not able to succeed. Could any one please help me out in resolving the above issue...Thanks in Advance
