将泛型词典转换为不同类型

Handle(_commands.ToDictionary(p => p.Key, p => (object)p.Value));

这不是世界上最有效率的事情,但在协方差出现之前,这就是休息。

也许这个函数对你有用

IEnumerable<KeyValuePair<string, object>> Convert(IDictionary<string, string> dic) {
    foreach(var item in dic) {
        yield return new KeyValuePair<string, object>(item.Key, item.Value);
    }
}

Handle(Convert(_commands));

这样可以吗?

Dictionary<int, string> dict = new Dictionary<int, string>();

dict.Add(1, "One");
dict.Add(2, "Two");
dict.Add(3, "Three");
dict.Add(4, "Four");
dict.Add(5, "Five");

object dictObj = (object)dict;

IDictionary temp = (IDictionary)dictObj;

Dictionary<int, object> objs = new Dictionary<int, object>();

foreach (DictionaryEntry de in temp)
{
    objs.Add((int)de.Key, (object)de.Value);
}

你不能用吗

Dim myDictionary AS New Dictionary(Of Object, Object)

这样就可以接受任何类型
