I am using following code to post multiline message on facebook wall/page. but it is appear as shown in image (the text are different here). here is my code.

string path = "/me/feed";
string token = fbLoginDialog.FacebookOAuthResult.AccessToken;

dynamic messagePost = new ExpandoObject();
messagePost.message = @"Hello guys!
How are you?
Can you help me on this?";

var fb = new FacebookClient(token);
try { var postId = fb.Post(path, messagePost); }  
catch (Exception ex) { MessageBox.Show(ex.Message); }

回答1:

Did you try Environment.NewLine?:

messagePost.message = "Hello guys!" + Environment.NewLine + 
                      "How are you?"+ Environment.NewLine +
                      "Can you help me on this?";

Environment.NewLine is a platform independent property that inserts new line char for the selected environment.

Or maybe you have a problem with your syntax and it should be:

messagePost.message = @"Hello guys!\r\n How are you?\r\n Can you help me on this?";
