InfoPath中的Rich Text Box是XHtml的格式，所以用\r\n或是用System.Environment.NewLine，都不會換行。

使用下列程式碼即可。

public void CTRL27_5_Clicked(object sender, ClickedEventArgs e)
{
    // 在此處寫入您的程式碼。
    XmlReader xr;
    XPathNavigator root = MainDataSource.CreateNavigator();
    XPathNavigator RichTextBox = root.SelectSingleNode("/my:myFields/my:ShowValue", NamespaceManager);
    string id = "12";
    string name = "余小章";
    xr = XmlReader.Create(new StringReader("<div xmlns=\"http://www.w3.org/1999/xhtml\">" + id + "</div>"));
    RichTextBox.AppendChild(xr);
    xr = XmlReader.Create(new StringReader("<div xmlns=\"http://www.w3.org/1999/xhtml\"> "+name+" </div>"));
    RichTextBox.AppendChild(xr);
}

或是使用

public void CTRL29_5_Clicked(object sender, ClickedEventArgs e)
{
    string id = "12";
    string name = "余小章";
    string str = string.Empty;
    XPathNavigator domNav = MainDataSource.CreateNavigator();
    string xhtmlRTFField = domNav.SelectSingleNode("/my:myFields/my:ShowValue", NamespaceManager).InnerXml;
    str += "<div xmlns=\"http://www.w3.org/1999/xhtml\">" + id + "</div>";
    str += "<div xmlns=\"http://www.w3.org/1999/xhtml\">" + name + "</div>";
    domNav.SelectSingleNode("/my:myFields/my:ShowValue", NamespaceManager).InnerXml = str;
}

以上方法都可以換行
