AppendLine is not inserting new line?

I have the following:

StringBuilder errors = new StringBuilder();

if(IsNullOrEmpty(value))
{
errors.AppendLine("Enter value");
}

if(IsNullOrEmpty(value2))
{
errors.AppendLine("Enter value 2");
}

I would expect this to display:

Enter value
Enter value 2

But it is displaying:

Enter value Enter value 2

I have also tried: AppendFormat("Enter value{0}",Environment.NewLine);

as well as with the \n character.

The errors string is outputted to an asp:Label like:

lblErrors.Text = errors.ToString();

in to string u can make as well errors.Append(Enviroment.NewLine);

@Brian in c# new line isn't "\n" "\r\n" is correct syntax of new line character:)

If you'd like to preserve all formatting (including tabs, consecutive white-space, etc), you can apply the white-space:pre style to your label or use an html pre element.

I would try to do something like

if(value.Empty == null){
   errors.AppendLine("Enter Value");
}

By the code you are showing it seems like it doesn't go into the if statement.

As mentioned in some of the comments, HTML does not respect the new line character \n. You need to use <br/> instead.
