Two Methods for deleting extra spaces on the compressed aspx page

Two methods:
1) read the aspx file in one row and process it
2) read the aspx file at one time and process it.
Processing logic:
Replace "with" "(replace two spaces with one space), replace all linefeeds with empty characters (limit compression)
Note:
1) when one row is used to process the ultimate compression, additional lines of controls on the server are required, for example
Copy codeThe Code is as follows:
Line 1: <asp: Label runat = "server"
Line 2: ID = "lb1 "....
Line 3:.../>

In this case, one row of data may cause a problem.

2) In addition, single line comments inline in JS scripts
We recommend that you use "/**/" instead "//"
Result:

The processing of one row is slightly faster than that of one-time processing. For the aspx files of 200 or 300 rows, the difference is within milliseconds. However, as the number of files increases, the gap should be reflected.
One-time read processing can be performed without extreme compression, so that you do not need to consider the problem of server controls and inline single row annotations.
I usually seldom use inline comments, single line comments, and server controls, so the compression effect is very obvious. Generally, the source code of 1/3-lines is compressed less than 50 lines, and the size is reduced by about.
However, this compression effect may be significantly related to whether you use the server-side data list control and how to use it. Generally, I only use repeater.

Copy codeThe Code is as follows:
Public static String Replace (String source, String oldStr, String newStr)
{
Int count = Regex. Matches (source, oldStr). Count;
For (int I = 0; I <count; I ++)
{
Source = source. Replace (oldStr, newStr );
}
Return source;
}
