ASP.NET通用模板 [英] ASP.NET Generic template

问题描述

我有一组类似的类（c1，c2，...）。


我想创建一个模板（或一个具有尽可能多抽象的页面
尽可能）复制/粘贴，并创建ASPX页面进行编辑

（添加/更新/ ...）这些类。

自定义页面对于每个班级，因为他们之间几乎没有差异




除了这个（复制的）模板之外，我还要定义班级的名称。 />
我想编辑。

以下生成错误，但你明白了：

public class TemplateEdit：System.Web.UI.Page

{

protected Class1 mainObject; //用Object替换Class1来编辑

protected string mainObjectName;

protected类型mainObjectType;


//定义主对象这里

mainObjectName =" Company" ;;

mainObjectType = typeof（Class1）;


//通用代码，相同在所有aspx页面上

this.mainObject =（mainObjectType）new Object（）;

this.mainObject =（mainObjectType）Session [mainObjectName];

Session [mainObjectName] = this.mainObject;


private void SubmitBtn_Click（object sender，

System.Web.UI.ImageClickEventArgs e）

{

// ....

}

I have a set of similar classes (c1, c2, ...).

I would like to create a template (or a page with as much abstraction
as possible) to copy/paste, and create ASPX pages to edit
(add/update/...) these classes.
A customised page for each class, beacause there are few differences
between them

On top of this (copied) template, I would define the name of the class
I want to edit.
The following generates error, but you get the idea:
public class TemplateEdit : System.Web.UI.Page
{
protected Class1 mainObject; //replace Class1 by the Object to edit
protected string mainObjectName;
protected Type mainObjectType;

//Define main object here
mainObjectName = "Company";
mainObjectType = typeof(Class1);

//Generic code, the same on all aspx pages
this.mainObject = (mainObjectType) new Object();
this.mainObject = (mainObjectType)Session[mainObjectName];
Session[mainObjectName] = this.mainObject;

private void SubmitBtn_Click(object sender,
System.Web.UI.ImageClickEventArgs e)
{
//....
}

推荐答案

我只是好奇你在这里想要完成的事情......看起来很多

你讨论的项目会比继承更好地服务

copy /粘贴。


示例：


公共类MyPageBase：Page {

pro tected object mainObject; //用Object替换Class1来编辑

protected string mainObjectName;

protected Type mainObjectType;

// etc

}


然后


公共类MyChildPage：MyBasePage {

}

I am just curious what you are trying to accomplish here .. it seems alot of
the items you discuss would be better served though inheritance than
copy/paste.

example :

public class MyPageBase : Page {
protected object mainObject; //replace Class1 by the Object to edit
protected string mainObjectName;
protected Type mainObjectType;
//etc
}

then

public class MyChildPage : MyBasePage {
}

公共类TemplateEdit：System.Web.UI.Page
{
protected Class1 mainObject; //用Object替换Class1来编辑
受保护的字符串mainObjectName;
protected类型mainObjectType;

//在此定义主对象
mainObjectName =" Company" ;;
mainObjectType = typeof（Class1）;

//通用代码，所有aspx页面都相同
this.mainObject =（mainObjectType）new Object（）;
this.mainObject =（mainObjectType）Session [mainObjectName];

}

很好，

这是解决方案的一部分，谢谢


但是仍然没有回答我的问题


假设我有一个session变量我想将这个主要对象转换为

特定的一个。

我需要在MyPageBase中写一个泛型类型


mainObject =（mainObjectTy PE）会话[mainObjectName]; //不用

工作


不能在自定义页面（AFAIK）中翻译成

Class1 mainObject = new（ Class1）;

mainObjectName =" Class1" ;;

mainObjectType = typeof（Class1）;


此行将是副本/粘贴在所有页面而不是MyPageBase

Very well,
This is part of the solution, thank you

but that still doesn''t answer my question

Suppose I have a session variable I want to cast this main object to a
specific one.
I would need to write a generic type in MyPageBase

mainObject = (mainObjectType)Session[mainObjectName]; // does not
work

can NOT be translated in the customised pages (AFAIK) into
Class1 mainObject = new (Class1);
mainObjectName = "Class1";
mainObjectType = typeof(Class1);

This line would be copy/pasted in all pages instead of in MyPageBase

我不明白你的问题的这一部分......你在问你怎么样？ b $ b可以为您的页面添加通用吗？


干杯，

I am not understanding this part of your question ... are you asking how you
can add a generic to your page base?

Cheers,
