如何使用Linq重新寫入？

Question

只是一個快速的問題..使用LINQ

var turbo = 
      (from t in _cat.Data 
       where t.Veh_ID == id && t.Engine == engine 
       select t.PartNum).FirstOrDefault(); 

我已經試過這樣的事情，但被卡住怎麼卡尼重新寫這個！

var t = _cat.Data.where (x =>x.Veh_ID == id && x.Engine == engine).Select() // << stuck here 

請幫忙，謝謝

在這裏你去

var turbo = _cat.Data.Where(t.Veh_ID == id && t.Engine == engine) 
        .Select(x => x.PartNumber) 
        .FirstOrDefault();
