在哪里可以找到 List.AddRange() 方法？
我有一些看起来很旧的代码，如下所示：
IList<KeyValuePair<string, ValuePair>> ServicePairs = new List<KeyValuePair<string, ValuePair>>();
// ...
foreach (KeyValuePair<string, string> Set in Services)
{
if (string.Format("{0} (Service)", Set.Value) == c.ColumnName)
{
ServicePairs.Add(new KeyValuePair<string, ValuePair>(c.Ordinal.ToString(), new ValuePair { Id = Set.Key, Title = Set.Value }));
}
}
Resharper 建议我通过将其转换为以下内容来对其进行一些修饰：
ServicePairs.AddRange(from Set in Services
where string.Format("{0} (Service)", Set.Value) == c.ColumnName
select new KeyValuePair<string, ValuePair>(
c.Ordinal.ToString(),
new ValuePair { Id = Set.Key, Title = Set.Value }));
我想知道的是 - 这个 AddRange() 在哪里方法来自 - 是来自 Microsoft Prism 还是其他地方？
更新：有人指出，这是 List 类的一部分。显然，它不是 IList 接口的一部分，这是我困惑的根源。谢谢大家。
I have some old school looking code that is as follows:
IList<KeyValuePair<string, ValuePair>> ServicePairs = new List<KeyValuePair<string, ValuePair>>();
// ...
foreach (KeyValuePair<string, string> Set in Services)
{
if (string.Format("{0} (Service)", Set.Value) == c.ColumnName)
{
ServicePairs.Add(new KeyValuePair<string, ValuePair>(c.Ordinal.ToString(), new ValuePair { Id = Set.Key, Title = Set.Value }));
}
}
Resharper is suggesting I pretty it up a bit by converting it to the following:
ServicePairs.AddRange(from Set in Services
where string.Format("{0} (Service)", Set.Value) == c.ColumnName
select new KeyValuePair<string, ValuePair>(
c.Ordinal.ToString(),
new ValuePair { Id = Set.Key, Title = Set.Value }));
What I'd like to know is - where does this AddRange() method come from - is it from Microsoft Prism or somewhere else?
UPDATE: It's been pointed out that this is part of the List<T> class. Apparently, it's not part of the IList<T> interface, which was the source of my confusion. Thanks everyone.

它是
List的一种方法 类。It's a method of the
List<T>class.它是
List的一部分是 BCL 的一部分。Its part of
List<T>which is part of the BCL.System.Collections.Genericiirc 中的List。List<T>inSystem.Collections.Genericiirc.在 VS 中查找的最简单方法是右键单击 AddRange 并选择“转到定义”，
您将在类的顶部看到一些变化
The easiest way to find out in VS if you right click on AddRange and select "Go To Definition"
You'll see some variation of this at the top of the Class
