使用字符串变量作为控件，项目和对象名称 [英] Use string variable for control, item and object name

问题描述

我需要类似的东西"

string obj= something;
this.obj.Visible = false;

不是

this.Controls[SomeButtonName].Visible = false;

或者告诉我从字符串执行此代码的方式"

string command = "this.something.visible=false";
execute(command);

非常感谢.

解决方案

您可能想查看devexpress论坛和博客.
他们对此有更多信息.

我需要类似的东西" :

 字符串 SomeButtonName = "  button1";
 this  .Controls [SomeButtonName] .Visible =  false ; 

或告诉我如何从字符串中执行此代码"

string command = "this.btn1.visible=false";
execute(command);

这是一个推迟编译和将字符串作为C#代码执行的问题，这是一个更深层的问题:如果搜索CP，您会发现在运行时执行时有许多出色的资源字符串中的代码.

我完全不清楚这两个问题与您提出的问题的总体权限之间的关系.

但是，希望对您有所帮助！

您尝试过System.Runtime.CompilerServices命名空间吗?

"I need something like that"

string obj= something;
this.obj.Visible = false;

Not

this.Controls[SomeButtonName].Visible = false;

"Or tell me the way to execute this code from the string"

string command = "this.something.visible=false";
execute(command);

Thanks very much.

解决方案

You might want to check on the devexpress forums and blogs.
They have some more information about this.

"I need something like that"

string ctrlname = btn1;
this.ctrlname.Visible = false;

Why you would ever want to use code like that is not something I understand, but it can be done:

string SomeButtonName = "button1";
this.Controls[SomeButtonName].Visible = false;

"Or tell me the way to execute this code from the string"

string command = "this.btn1.visible=false";
execute(command);

This, a question of deferred compilation and execution of a string as C# code, is a much deeper question: you will find, if you search CP, several excellent resources on executing at run-time code in a string.

I am completely unclear how these two questions relate to the overall issue of permissions raised by your question.

But, hope this helps !

did u try System.Runtime.CompilerServices Namespace ?
