在 C# 中建立具有指定初始大小的區分大小寫的混合字典
要建立具有指定初始大小的區分大小寫的混合字典,程式碼如下 -
範例
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);
}
}輸出
將產生以下輸出 -
Key/Value pairs... Key = A, Value = AB Key = B, Value = BC Key = C, Value = DE Key = D, Value = FG Key = e, Value = fg
範例
現在讓我們看另一個例子 -
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);
}
}輸出
將產生以下錯誤 -
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
