Serializing string with newlines adds extra lines

[mwhouser]

YamlDotNet appears to double the end-of-line markers.

For example:

var obj = new
{
	Data = "123\n456"
};

var serializer = new YamlDotNet.Serialization.Serializer();
string yaml = serializer.Serialize(obj);
Console.WriteLine(yaml);

outputs the following:

Data: >-
  123

  456

Internally, when I inspect the yaml variable, the text includes Data: >-\r\n 123\r\n\r\n 456\r\n. So it is indeed adding an extra line.

Whereas I would expect it to be:

Data: >-
  123
  456

and internally Data: >-\r\n 123\r\n 456\r\n.

I'm not sure if I'm seeing the same issue here but in reverse with deserialization as well.

I'm trying to load in some text from a document section like this:

---
Some other text is here which starts our adventure...
There are many lines to this text.

Some are farther away then others and **bold**.

However, when I deserialize this the value only contains one newline where the blank line is instead of one at the end of each line.

parser.Current.ToString()
"Scalar [anchor = , tag = , value = Some other text is here which starts our adventure... There are many lines to this text.\nSome are farther away then others and **bold**., style = Plain, isPlainImplicit = True, isQuotedImplicit = False]"

Adding the following attribute to your property solves this issue.

using YamlDotNet.Core;
using YamlDotNet.Serialization;
...
[YamlMember(ScalarStyle = ScalarStyle.Literal)]
public string MyProp { get; set; }

I'm sorry I was unable to answer this question in a timely fashion. As you have certainly moved on to other things, I will close this issue, but feel free to reopen it if necessary.
