ASP.NET实现纯文本转HTML ,可以实现的功能:输入:"ab\r\ncde\r\nfghi"输出:"abcdefghi"，注意无论任何输出和都要配对出现，且和之间不能为空

public static string Text2HtmlSimple(string input)

02 {

`03`	`StringBuilder sb =` `new` `StringBuilder();`

`04`	`sb.Append("<p>");`

`05`	`int` `index = 0;`

06 do

07 {

`08`	`string` `toAppend =` `string.Empty;`

`09`	`int` `pos = input.IndexOf("\r\n", index);`

`10`	`if` `(pos == 0)`

11 {

`12`	`index = pos + 2;`

13 }

`14`	`else` `if` `(pos == input.Length - 2)`

15 {

`16`	`toAppend = input.Substring(index, pos - index);`

`17`	`if` `(!string.IsNullOrEmpty(toAppend))`

18 {

`19`	`sb.AppendFormat("{0}</p>", toAppend);`

20 }

`21`	`index = pos + 2;`

22 }

`23`	`else` `if` `(pos > 0)`

24 {

`25`	`toAppend = input.Substring(index, pos - index);`

`26`	`if` `(!string.IsNullOrEmpty(toAppend))`

27 {

`28`	`sb.AppendFormat("{0}</p><p>", toAppend);`

29 }

`30`	`index = pos + 2;`

31 }

32 else

33 {

`34`	`toAppend = input.Substring(index, input.Length - index);`

`35`	`sb.AppendFormat("{0}</p>", toAppend);`

36 break;

37 }

38 }

`39`	`while` `(index < input.Length);`

`40`	`return` `sb.ToString();`

41 }
