C# List 复制
废话不多说,看代码:
方法一:
List<string> t = new List<string>(); //original
List<string> t2 = new List<string>(t.ToArray()); // copy of t
方法二:
It is a one liner using LINQ.
List<string> list1 = new List<string>(); List<string> list2 = new List<string>(); // This will copy all the items from list 1 to list 2 list1.ForEach(i => list2.Add(i));
C#深度拷贝(Deep Copy)
Hashtable和ArrayList等经常需要深度拷贝,而.Net没有现成的函数可以调用,
public object Clone()
{
BinaryFormatter Formatter = new BinaryFormatter(null, new StreamingContext(StreamingContextStates.Clone));
MemoryStream stream = new MemoryStream();
Formatter.Serialize(stream, this);
stream.Position = 0;
object clonedObj = Formatter.Deserialize(stream);
stream.Close();
return clonedObj;
}
继承了Clonable接口之后,像这样重写Clone()方法就可以了,他利用了序列化和反序列化的原理,将序列化的流丢入内存,再从内存中反序列化回来就OK了!
