Answer 1

check out the System.Collections.Concurrent - Namespace! http://msdn.microsoft.com/en-us/library/system.collections.concurrent.aspx

Answer 2

对于我来说，这听起来像ConcurrentDictionary<TKey, TValue> ，如果您安装了Reactive Extensions ，则可以在.NET 4.0 或 .NET 3.5中使用。

Answer 3

Have a look at the ConcurrentDictionary here: http://msdn.microsoft.com/en-us/library/dd287191.aspx . This should do what you're looking for. Keep in mind, it's .Net 4 only.

Answer 4

You could also write your own class by using the ReaderWriterLockSlim Class .

Otherwise simply take a look into the System.Collections.Concurrent Namespace .
