该方法用于从排序字典< TKey、TVaLue>T1 中移除所有键/值对。
语法:
public void Clear ();
以下是说明上述方法使用的程序:
例 1:
// C# code to remove all pairs
// from SortedDictionary
using System;
using System.Collections.Generic;
class GFG {
// Driver code
public static void Main()
{
// Create a new dictionary of
// strings, with string keys.
SortedDictionary<string, string> myDict =
new SortedDictionary<string, string>();
// Adding key/value pairs in myDict
myDict.Add("Australia", "Canberra");
myDict.Add("Belgium", "Brussels");
myDict.Add("Netherlands", "Amsterdam");
myDict.Add("China", "Beijing");
myDict.Add("Russia", "Moscow");
myDict.Add("India", "New Delhi");
// To get count of key/value pairs in myDict
Console.WriteLine("Total key/value pairs "
+ "in myDict are : " + myDict.Count);
// Remove all pairs from the Dictionary
myDict.Clear();
Console.WriteLine("After clear operation");
// To get count of key/value pairs in myDict
Console.WriteLine("Total key/value pairs in"
+ " myDict are : " + myDict.Count);
}
}
输出:
Total key/value pairs in myDict are : 6
After clear operation
Total key/value pairs in myDict are : 0
