要创建指定初始大小的区分大小写的 HybridDictionary，代码如下 −
示例
using System;
using System.Collections;
using System.Collections.Specialized;
public class Demo {
public static void Main(){
HybridDictionary myDict = new HybridDictionary(5, false);
myDict.Add("A", "AB");
myDict.Add("B", "BC");
myDict.Add("C", "DE");
myDict.Add("D", "FG");
myDict.Add("e", "fg");
Console.WriteLine("Key/Value pairs...");
foreach(DictionaryEntry de in myDict)
Console.WriteLine("Key = "+de.Key + ", Value = " + de.Value);
}
}
输出
这将产生以下输出 −
Key/Value pairs... Key = A, Value = AB Key = B, Value = BC Key = C, Value = DE Key = D, Value = FG Key = e, Value = fg
示例
现在让我们看另一个例子 −
using System;
using System.Collections;
using System.Collections.Specialized;
public class Demo {
public static void Main(){
HybridDictionary myDict = new HybridDictionary(5, true);
myDict.Add("A", "AB");
myDict.Add("B", "BC");
myDict.Add("C", "DE");
myDict.Add("e", "fg");
myDict.Add("E", "FG");
Console.WriteLine("key/Value pairs...");
foreach(DictionaryEntry de in myDict)
Console.WriteLine("Key = "+de.Key + ", Value = " + de.Value);
}
}
输出
这将产生以下错误 −
Run-time exception : An entry with the same key already exists. Stack Trace: [System.ArgumentException: An entry with the same key already exists.] at System.Collections.Specialized.ListDictionary.Add(Object key, Object value) at System.Collections.Specialized.HybridDictionary.Add(Object key, Object value) at Demo.Main() :line 15
