谁能向我解释以下代码? [英] Can anyone explain to me about the following code?

问题描述

String tempStr1 = "";
String.Format("{1} ", "", Request["Name"]);
   Display.Text = tempStr1;

非常感谢.

Thanks a lot.

推荐答案

// create a temporary string containing no characters
String tempStr1 = "";
// format a string containing the contents of a field called Name,
// but don't save the new string anywhere
String.Format("{1} ", "", Request["Name"]);
// set the text content of variable Display to the string tempStr1
// which is nothing
   Display.Text = tempStr1;

该代码不会在Display控件中显示任何内容.
如果按以下方式进行更改，则可以从"Display"控件的请求中获取"Name"-

That code would display nothing in the Display control.

If you change it as follows you will get the "Name" from your request in the "Display" control-

String tempStr1 = "";
tempStr1 = String.Format("Hi {0}!", Request["Name"]);
   Display.Text = tempStr1;

使用上面的代码，如果Request["Name"]是"noname89757"，则"Display"控件将显示"Hi noname89757!"

Using the abouve code, if Request["Name"] is "noname89757" then "Display" control would display "Hi noname89757!"
