将var数据转换为哈希表

Question

是否可以将var数据转换为哈希表？

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

Answer 1

假设您希望将Product_ID用作哈希表中的键，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;
}
