Html format conversion of text characters

In the previous section, I made a forum on the imitation bubble network and encountered the problem of converting text symbols into the corresponding html format. I tried several methods and made a simple format conversion class:

Convert webpage format to text box format:

Code

Public string Encode (string str)

{

Str = str. Replace ("&", "& amp ");

Str = str. Replace ("","");

Str = str. Replace ("", "& quot ;");

Str = str. Replace ("", "& nbsp ;");

Str = str. Replace ("<", "& lt ;");

Str = str. Replace (">", "& gt ;");

Str = str. Replace ("", "<br/> ");

Str = str. Replace ("", "<br> ");

Return str;

}

Text Box format to webpage format:

Code

Public string Decode (string str)

{

Str = str. Replace ("<br/> ","");

Str = str. Replace ("<br> ","");

Str = str. Replace ("& gt", "> ");

Str = str. Replace ("& lt", "<");

Str = str. Replace ("& nbsp ;","");

Str = str. Replace ("& quot ;",""");

Str = str. Replace ("","");

Str = str. Replace ("& amp ","&");

Return str;

}

You can call the corresponding method when submitting the database or displaying the webpage.
