在C#并发集合 [英] Concurrent collections in C#
问题描述
我在寻找在C#或至少是一个集得到一个并发收集的方式,支持并行枚举。现在,我得到一个InvalidOperationException集合时在其上我迭代变化。我可以只复制深收集并配有私人拷贝工作,但我不知道是否有可能是一个更好的办法
代码段:
的foreach(字符串S IN(列表<串GT;)callingForm.Invoke(callingForm.delegateGetKillStrings))
{
//做一些爵士
}

我把答案,但也发现,我需要确保这是写入所需的收集代码试图获得一个锁。
私人无效addKillString(String s)将
{
锁(killStrings)
{
killStrings.Add(S);
}
}
其他不是做深复制你最好的选择可能是锁定集合:
列表<串GT;的thelist =(列表<串GT;)callingForm.Invoke(callingForm.delegateGetKillStrings);
锁(theList.SyncRoot){
的foreach(字符串s中的thelist){
//做一些爵士
}
}
I'm looking for a way of getting a concurrent collection in C# or at least a collection which supports a concurrent enumerator. Right now I'm getting an InvalidOperationException when the collection over which I'm iterating changes. I could just deep copy the collection and work with a private copy but I'm wondering if there is perhaps a better way
Code snippet:
foreach (String s in (List<String> )callingForm.Invoke(callingForm.delegateGetKillStrings))
{
//do some jazz
}
--edit--
I took the answer but also found that I needed to ensure that the code which was writing to the collection needed to attempt to get a lock as well.
private void addKillString(String s)
{
lock (killStrings)
{
killStrings.Add(s);
}
}
Other than doing a deep-copy your best bet might be to lock the collection:
List<string> theList = (List<String> )callingForm.Invoke(callingForm.delegateGetKillStrings);
lock(theList.SyncRoot) {
foreach(string s in theList) {
// Do some Jazz
}
}
