If you can use a tool like "dapper", this can be simply:

int[] ages = { 20, 21, 22 }; // could be any common list-like type
var rows = connection.Query("SELECT * from TableA WHERE Age IN @ages",
          new { ages }).ToList();

Dapper will handle unwrapping this to individual parameters for you.
