C# - Multiline TextBox Question: how to insert a newline ?

Question

Hello to all C# specialists here a easy question from a C# newbie :) Does anybody know how to insert a newline character into a string which is inserted into a multiline textBox (all this with Visual Studio.Net 2003 but for a smart device application under WinCE4.2) I tried the following code and receive a square instead of the line break in the output: // code extract sample ... stringNewError = 
 New Error Number ... textBox1.Text = TextBox1.Text + stringNewError; ... // end of code extract sample The output shows the old textBox Text content plus the new added stringNewError content in multiple lines but directly attached within the same line (instead starting with a new line ) just being seperated by a little empty square symbol. The target should be to have the stringNewError starting with a new line ... Any sample explanation or help would be very welcome Thx Max

Thanks this was the good solution this works fine with Windows CE. The 
 method is working correct. The Environment.NewLine isn't working under WinCE :( because not compilable. Thanks very much - for all those who gave their ideas thanks too for those who gave a non working idea too. Bye Max :)

Thanks but unfortunately this is not compilable with the compact framework because the Environment has no newline definition ?! Here the Visual Studio 2003 compiler message: ...\Menu_Error.cs(311): 'System.Environment' does not contain a definition for 'NewLine' for the following code line: textBox1.Text += Environment.NewLine + (nextErreurString + time.ToString()); But thanks anyway - this way works fine for WinXP but not for WinCE ! Thanks anyway Max

Also you can try this: ... stringNewError = New Error Number ... textBox1.Text = textBox1.Text + Environment.NewLine + stringNewError; ... or ... stringNewError = New Error Number ... textBox1.Text += Environment.NewLine + stringNewError; //is the same ... Good luck!!

I'm not entirely sure what you're after but if you want to get a new line try to write the line change as 
 instead of just 
 like below: ... stringNewError = 
 New Error Number ... textBox1.Text = TextBox1.Text + stringNewError; ... Good luck!
