要检查 SortedList 是否为只读，代码如下 −
示例
using System;
using System.Collections;
public class Demo {
public static void Main(String[] args) {
SortedList list = new SortedList();
list.Add("One", "IT");
list.Add("Two ", "Operations");
list.Add("Three", "Marketing");
list.Add("Four", "Purchase");
list.Add("Five", "Sales");
list.Add("Six", "Finance");
Console.WriteLine("SortedList elements...");
foreach(DictionaryEntry d in list) {
Console.WriteLine(d.Key + " " + d.Value);
}
Console.WriteLine("
List of values...SortedList");
IList col = list.GetValueList();
foreach(string res in col) {
Console.WriteLine(res);
}
Console.WriteLine("
SortedList is read-only? = "+list.IsReadOnly);
}
}
输出
这将产生以下输出 −
SortedList elements... Five Sales Four Purchase One IT Six Finance Three Marketing Two Operations List of values...SortedList Sales Purchase IT Finance Marketing Operations SortedList is read-only? = False
示例
让我们看另一个例子 −
using System;
using System.Collections;
public class Demo {
public static void Main(String[] args) {
SortedList list = new SortedList();
list.Add("One", "Finance");
list.Add("Two", "Marketing");
list.Add("Three", "Sales");
list.Add("Four", "Purchase");
list.Add("Five", "Operations");
list.Add("Six", "IT");
Console.WriteLine("SortedList elements...");
foreach(DictionaryEntry d in list) {
Console.WriteLine(d.Key + " " + d.Value);
}
Console.WriteLine("
Index at key One = "+list.IndexOfKey("One"));
ICollection col = list.Keys;
Console.WriteLine("
Collection of Keys...");
foreach(string res in col)
Console.WriteLine(res);
Console.WriteLine("
SortedList is read-only? = "+list.IsReadOnly);
}
}
输出
这将产生以下输出 −
SortedList elements... Five Operations Four Purchase One Finance Six IT Three Sales Two Marketing Index at key One = 2 Collection of Keys... Five Four One Six Three Two SortedList is read-only? = False
