c# - 从 Collection 到 List 的最快转换

Question

我想避免的事情:

ManagementClass m = new ManagementClass("Win32_LogicalDisk");

ManagementObjectCollection managementObjects = m.GetInstances();

List<ManagementObject> managementList = new List<ManagementObject>();

foreach(ManagementObject m in managementObjects){

    managementList.Add(m);

}

有没有办法将该集合放入类似于以下内容的列表中:

List<ManagementObject> managementList = new List<ManagementObjec>(collection_array);

Answer 1

什么版本的框架？对于 3.5，您大概可以使用:

List<ManagementObject> managementList = managementObjects.Cast<ManagementObject>().ToList();

(经过编辑删除了更简单的版本；我检查过，ManagementObjectCollection 只实现了非通用的 IEnumerable 形式)
