我有一个字典数据类型.我的问题是,Dictionary.Keys.ToList()[i]总是对应于Dictionary.Values.ToList()[i]？也就是说,以下测试总是会通过
public void DictionaryTest(int i,Dictionary<U,T> dict)
{
var key = dict.Keys.ToList()[i];
Assert.AreEqual(dict[key],dict.Values.ToList()[i]);
}
解决方法
检查
Dictionary.Keys Property的MSDN条目：
The order of the keys in the Dictionary.KeyCollection is unspecified,but it is the same order as the associated values in the Dictionary.ValueCollection returned by the Values property.
