Hashtable.Values属性用于获取包含Hashtable中的值的ICollection。
句法:

返回值:该属性返回一个ICollection,其中包含Hashtable中的值。
笔记:
- ICollection中值的顺序未指定。
- 检索此属性的值是O(1)操作。
下面的程序说明了上面讨论的属性的用法:
范例1:
// C# code to get an ICollection containing
// the values in the Hashtable.
using System;
using System.Collections;
class GFG {
// Driver code
public static void Main()
{
// Creating a Hashtable
Hashtable myTable = new Hashtable();
// Adding elements in Hashtable
myTable.Add("g", "geeks");
myTable.Add("c", "c++");
myTable.Add("d", "data structures");
myTable.Add("q", "quiz");
// Get a collection of the values
ICollection c = myTable.Values;
// Displaying the contents
foreach(string str in c)
Console.WriteLine(str + myTable[str]);
}
}
输出:
data structures
c++
quiz
geeks
范例2:
// C# code to get an ICollection containing
// the values in the Hashtable.
using System;
using System.Collections;
class GFG {
// Driver code
public static void Main()
{
// Creating a Hashtable
Hashtable myTable = new Hashtable();
// Adding elements in Hashtable
myTable.Add("India", "Country");
myTable.Add("Chandigarh", "City");
myTable.Add("Mars", "Planet");
myTable.Add("China", "Country");
// Get a collection of the values
ICollection c = myTable.Values;
// Displaying the contents
foreach(string str in c)
Console.WriteLine(str + myTable[str]);
}
}
输出:
