它是一个有效的SQLite查询吗？

Question

出于某种原因，我有一个未处理的异常，它是正确的语法吗？

command.CommandText = "INSERT INTO tblUsers (Username, UserEmail, FirstName, LastName) VALUES (@Username, @UserEmail, @FirstName, @LastName)";

command.Parameters.AddWithValue("@UserEmail", user.Email);
command.Parameters.AddWithValue("@Username",  user.UserName);
command.Parameters.AddWithValue("@FirstName", user.FName);
command.Parameters.AddWithValue("@LastName",  user.LName);
