我試圖刪除字典第三級中的信息,並且只能在刪除此信息後使用它。 但我不能,我做錯了什麼?在字典的第三級刪除項目
public class Person
{
int id;
string name;
public string Name
{
get { return name; }
set { name = value; }
}
public int ID
{
get { return id; }
set { id = value; }
}
public List<Product> ListProd;
}
public class Product
{
public int idProd;
public string Description;
public List<Tax> listTax;
}
public class Tax
{
public int idTax;
public string Value;
}
//Method
public void SomeMethod()
{
Dictionary<int, List<int>> dicRemove = new Dictionary<int, List<int>>();
List<int> listTaxToRemove = new List<int>();
for (int m = 8; m < 10; m++)
{
listTaxToRemove.Add(m);
}
dicRemove.Add(10, listTaxToRemove);
Dictionary<int, List<Person>> dic = new Dictionary<int, List<Person>>();
List<Person> list = new List<Person>();
for (int i = 0; i < 2; i++)
{
Person d = new Person();
d.ID = i;
d.Name = "Person " + i;
d.ListProd = new List<Product>();
for (int j = 3; j < 6; j++)
{
Product p = new Product();
p.idProd = j;
p.Description = "Product " + j;
d.ListProd.Add(p);
p.listTax = new List<Tax>();
for (int m = 7; m < 10; m++)
{
Tax t = new Tax();
t.idTax = m;
t.Value = "Tax " + m;
p.listTax.Add(t);
}
}
list.Add(d);
}
dic.Add(10, list);
var q = dic.Select(s => s.Value
.Select(s1 => s1.ListProd
.Select(s2 => s2.listTax
.RemoveAll(r =>!dicRemove[s.Key].Contains(r.idTax))))).ToList();
}
我嘗試了很多方法,通過迭代,這種方法剛剛刪除了不必要的記錄。
謝謝!
務必添加一種編程語言的標籤! –
