如何存储和检索类和数组,在会话中列出 [英] How to store&retrieve a class and arrays, list in session
本文介绍了如何存储和检索类和数组,在会话中列出的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我想在会话中存储类,数组和List。然后在asp.net c#中从会话中检索它们。帮助人们!
什么我试过了:
给我一个例子。在asp.net c#。我不知道怎么做。多次google但是没有得到确切的结果。
解决方案
假设你有一个类元素数组:
MyClass [] mca = new MyClass [ 100 ];
for ( int i = 0 ; i < 100 ; i ++)
{
mca [i ] = new MyClass(i);
}然后将其存储到Session中是微不足道的:
会话[ MyArray] = mca;检索它并不复杂:
MyClass [] mca = Session [MyArray] as MyClass [];
if(mca!= null)
{
...
}列表,数组,类实例 - 所有相同的技术。
列表obj =新列表();
obj.Add(1)
会话[会话] = obj;
并将类型转换回所需的列表。
同样可以完成对于任何复杂的对象。
I want to store class,arrays and List in session.Then retrieve them back from session in asp.net c#.Help guys!
What I have tried:
Give me an example guys.!In asp.net c#.I don't know how to do this.Googled many times but didn't get exact results.
解决方案
Assuming you have an array of your class elements:
MyClass[] mca = new MyClass[100]; for (int i = 0; i < 100; i++) { mca[i] = new MyClass(i); }Then storing it into the Session is trivial:
Session["MyArray"] = mca;And retrieving it is not complex either:
MyClass[] mca = Session["MyArray"] as MyClass[]; if (mca != null) { ... }Lists, arrays, class instances - all the same technique.
List obj = new List();
obj.Add(1)
Session["Session"] = obj;
and typecast back to list where it requires.
same can be done for any complex object.
