Print out the keys and Data of a Hashtable in C# .NET 1.1
提问by David Basarab
I need debug some old code that uses a Hashtable to store response from various threads.
我需要调试一些使用 Hashtable 存储来自各个线程的响应的旧代码。
I need a way to go through the entire Hashtable and print out both keys and the data in the Hastable.
我需要一种方法来遍历整个 Hashtable 并打印出 Hastable 中的键和数据。
How can this be done?
如何才能做到这一点？

foreach(string key in hashTable.Keys)
{
Console.WriteLine(String.Format("{0}: {1}", key, hashTable[key]));
}

public static void PrintKeysAndValues( Hashtable myList ) {
IDictionaryEnumerator myEnumerator = myList.GetEnumerator();
Console.WriteLine( "\t-KEY-\t-VALUE-" );
while ( myEnumerator.MoveNext() )
Console.WriteLine("\t{0}:\t{1}", myEnumerator.Key, myEnumerator.Value);
Console.WriteLine();
}

This should work for pretty much every version of the framework...
这应该适用于几乎所有版本的框架......
foreach (string HashKey in TargetHash.Keys)
{
Console.WriteLine("Key: " + HashKey + " Value: " + TargetHash[HashKey]);
}
The trick is that you can get a list/collection of the keys (or the values) of a given hash to iterate through.
诀窍是您可以获得给定散列的键（或值）的列表/集合以进行迭代。
EDIT: Wow, you try to pretty your code a little and next thing ya know there 5 answers... 8^D

I also found that this will work too.
我还发现这也会起作用。
System.Collections.IDictionaryEnumerator enumerator = hashTable.GetEnumerator();
while (enumerator.MoveNext())
{
string key = enumerator.Key.ToString();
string value = enumerator.Value.ToString();
Console.WriteLine(("Key = '{0}'; Value = '{0}'", key, value);
}
Thanks for the help.
谢谢您的帮助。

I like:
我喜欢：
foreach(DictionaryEntry entry in hashtable)
{
Console.WriteLine(entry.Key + ":" + entry.Value);
}
