What error are you getting? If you wrap this section of code in a try/catch block, you can actually find out what the problem is. I suspect the issue is a permissions issue, but only you can verify that. This is your opportunity to show off your debugging skills.

That's natural since you're trying to open the file two times: What's the purpose of the

C#

using (FileStream fs = File.Create(path))

if you then open again the file (with new StreamWriter("C:\\mytest.txt");)?

See, for instance: "C# Using StreamWriter"[^].

The issue you are getting is because you've just created the file using the line:

C#

using (FileStream fs = File.Create(path))

The file is open at this point, and you then attempt to open the same file again using:

C#

TextWriter sw = new StreamWriter("C:\\mytest.txt");//error is coming here

Use one or the other. Not both.
