Several line breaks in C #

Set the Multiline attribute of TextBox in winform to true, input several characters and press enter, save it to the database, read it from the database, and assign the value to TextBox. The linefeed is lost. Replace "" with "" In the read string to solve the problem.

1. The linefeed in TextBox is :"".

2. The line break (Environment. NewLine) in Windows is ""

3. The line break of MessageBox. Show () is ""

4. the Console line break is ""

After reading it from the database, the linefeed is inexplicably lost. Replace "" with "" for correct display format ""

The linefeed is only for the platform. The Unix/Linux platform linefeed is "".

To ensure the versatility of the platform, it is best to use Environment. NewLine.
