下一行..有什么用? [英] What is the use of following line ..?

问题描述

文字ltrlCloseWindowText =(文字)this.Page.Master.FindControl("ltrlCloseWindowText");

Literal ltrlCloseWindowText = (Literal)this.Page.Master.FindControl("ltrlCloseWindowText");

推荐答案

从下至上阅读.希望您能理解这个奇怪的书面解释.如果没有让我知道，我会尝试将其放入另一种形式.

P.S.我打破了代码行并解释了每个部分.

Read from bottom to top. I hope you will understand this weirdly written explanation. if not let me know and I will try to put it in another form.

P.S. I broke the line of code and explained each segment.

// 4. create a literal control variable to hold a literal control we find from somewhere else
Literal ltrlCloseWindowText 

// 3. assignment
 =
// 2. type cast the generic control type to literal control
 (Literal) 

// 1. Find a control names ltrlCloseWindowText in the masterpage associated with this page.
this.Page.Master.FindControl("ltrlCloseWindowText"); 

简而言之，我们想在masterpage 中找到与名为ltrlCloseWindowText的文字控件关联的值，并在内容页面中使用它.

in short, we want to find the value associated with some literal control named ltrlCloseWindowText in masterpage and use it in content page.

它进行搜索，如果找到，则返回ID为ltrlCloseWindowText的控件.该控件应为Literal控件类型.

It searches for and if found returns the control with ID ltrlCloseWindowText. The control is expected to be of control type Literal.
