Is there a way to use a tab character like a new line character inside the Environment class, instead of using \"\\t\"?
\"\\t\"
If you really wanted to you, you could add a reference and use Microsoft.VisualBasic.Constants.vbTab. But the tab character is not something that changes based on your environment so System.Environment wouldn't have a property for you.
Microsoft.VisualBasic.Constants.vbTab
System.Environment
