将var数据转换为散列表

Question

是否可以将var数据转换为散列表？

Hashtable hsTest = new Hashtable(); 
     var oFeat = (from t in db.test 
        where t.Product_ID == iProductID 
        select t); 

Answer 1

假设您想要将Product_ID用作散列表中的键，并将Product_Name用作值。你可以这样做：

Hashtable hsTest = new Hashtable(); 
var oFeat = (from t in db.test 
      where t.Product_ID == iProductID 
      select t); 
foreach (var product in oFeat) { 
    hsTest[product.Product_ID] = product.Product_Name; 
}
