How to loop through a SortedList, getting both the key and the value
提问by Wayneio
The following code loops through a list and gets the values, but how would I write a similar statement that gets both the keys and the values
下面的代码循环遍历一个列表并获取值，但是我将如何编写一个类似的语句来获取键和值
foreach (string value in list.Values)
{
Console.WriteLine(value);
}
e.g something like this
例如这样的事情
foreach (string value in list.Values)
{
Console.WriteLine(value);
Console.WriteLine(list.key);
}
code for the list is:
该列表的代码是：
SortedList<string, string> list = new SortedList<string, string>();
采纳答案by Sergey Berezovskiy
foreach (KeyValuePair<string, string> kvp in list)
{
Console.WriteLine(kvp.Value);
Console.WriteLine(kvp.Key);
}
From msdn:
从msdn：
GetEnumerator returns an enumerator of type KeyValuePair<TKey, TValue>that iterates through the SortedList<TKey, TValue>.
GetEnumerator 返回一个类型的枚举器，该枚举器KeyValuePair<TKey, TValue>遍历SortedList<TKey, TValue>.
As Jon stated, you can use varkeyword instead of writing type name of iteration variable (type will be inferred from usage):
正如 Jon 所说，您可以使用var关键字而不是编写迭代变量的类型名称（类型将根据使用情况推断）：
foreach (var kvp in list)
{
Console.WriteLine(kvp.Value);
Console.WriteLine(kvp.Key);
}
回答by Chu Chau
bool value = list[key];
this can help you.
这可以帮助你。

Just iterated using the keys and get the value for each key:
只需使用键进行迭代并获取每个键的值：
SortedList<string, string> info = new SortedList<string, string>();
info.Add("path", "път");
info.Add("folder", "директория");
info.Add("directory", "директория");
info.Add("file", "Файл");
foreach (string key in info.Keys)
{
Console.WriteLine("\t{0}\t{1}", key, info[key]);
}

Apologies...
道歉...
this was wrong topic (loop through values). My issue was looping through the key value pairs, not just the values. Will leave this here if there are no objections as a possible option to get values from SortedList collection.
这是错误的主题（循环遍历值）。我的问题是遍历键值对，而不仅仅是值。如果没有反对意见，将把它留在这里作为从 SortedList 集合中获取值的可能选项。
I just tried to figure out this error as well and my solution was to use the DictionaryEntrytype to replace the erroring out KeyValuePairtype.
Found from MS reference
https://msdn.microsoft.com/en-us/library/system.collections.dictionaryentry(v=vs.100).aspx
我也只是试图找出这个错误，我的解决方案是使用该DictionaryEntry类型来替换出错的KeyValuePair类型。从 MS 参考https://msdn.microsoft.com/en-us/library/system.collections.dictionaryentry(v=vs.100).aspx 中找到
In my case, I had code creating a SortedListtype collection and neither the varor KeyValuePairtypes worked (varerrored out when trying to read the key/value from the collection item and the KeyValuePairerrored out in the initial loop definition. Both errored out with "Specified cast is not valid")
就我而言，我有代码创建了一个SortedList类型集合，但varorKeyValuePair类型都不起作用（var尝试从集合项中读取键/值时KeyValuePair出错，并且在初始循环定义中出错。两者都出错了"Specified cast is not valid"）
So here is sample of code that worked for me:
所以这里是对我有用的代码示例：
SortedList _dims = GetList("mysortedlist");
foreach (DictionaryEntry kvp in _dims)
{
Console.WriteLine(kvp.Key.ToString());
Console.WriteLine(kvp.Value.ToString());
}
