Dictionary类型转换问题

[三碗猪脚]

怎么用泛型的方式把Dictionary<object,object>转换为指定类型如Dictionary<int,string>或者Dictionary<string,int>等等

[正怒月神]

Dictionary<object, object> dict1 = new Dictionary<object, object>();
            dict1.Add("1", 1);
            dict1.Add("2", 2);
            dict1.Add("3", 3);

            Dictionary<string, int> dict2 = new Dictionary<string, int>();
            dict2 = dict1.ToDictionary(
                key=>(string)key.Key,
                value=>(int)value.Value);

无法直接转换 除非把里面的元素一个一个取出来转换后加入到新的字典 Dictionary<T1,T2> Convert<T1,T2>(Dictionary<object,object> source) { var dest =new Dictionary<T1,T2>(); foreach(var pair in source) { dest[(T1)pair.Key] = (T2)pair.Value; } }

上面忘了 return dest;
