<t>Use replace with Environment.NewLine<br/>
<br/>
myString = myString.Replace(System.Environment.NewLine, "replacement text"); //add a line terminating ;<br/>
<br/>
```<br/>
<br/>
As mentioned in other posts, if the string comes from another environment (OS) then you'd need to replace that particular environments implementation of [new line control characters](http://en.wikipedia.org/wiki/Newline).</t>
