VB.NET REPLACE function

I am using replace function to replace a character in the file 

sw.WriteLine(Regex.Replace(strLine, "\\", Chr(13)))

This code is working fine, but now I want to replace two times and I want to use the replace function twice. Something like this, but it is not working . Can anyone tell me how to use Replace function multiple times?

sw.WriteLine(Regex.Replace(strLine, "\\", Chr(13)).Replace(strLine, Chr(13), ""))

Replace a carriage return in a string may be the following ways: str_souce = str_source.Replace(vbCrLf, "") str_souce = str_source.Replace(chr(13) & chr(10), "") str_souce = str_source.Replace(environment.newline, "")

if none above works, try the following one. It can even works for a third party software str_souce = str_source.Replace(vbCr, "").Replace(vbLf, " ")

Your second Replace is using the String.Replace extension, not the Regex.Replace method.

The Regex.Replace function returns a string, not a regex, which is why your second regex call isn't working. For multiple Regex.Replace calls, you would have to do each one individually or modify your replacement statement.

You could probably just use the String.Replace function for this:

sw.WriteLine(strLine.Replace("\\", Chr(13)).Replace(Chr(13), ""))

sw.WriteLine(Regex.Replace(Regex.Replace(strLine, "\\", Chr(13)), Chr(13), "")

Here it is more laid out, so you can see what's going on:

Dim firstIteration = Regex.Replace(strLine, "\\", Chr(13))

Dim secondIteration = Regex.Replace(firstIteration, Chr(13), "")

sw.WriteLine(secondIteration)
