Question

我有一个WebBrowser（WinPhone C＃），我在CodeBehind中设置了NavigateToString。这里有完整的代码：

string f = "<!DOCTYPE HTML PUBLIC ' -//W3C//DTD HTML 4.01 Transitional//EN' 'http://www.w3.org/TR/html4/loose.dtd'><?xml version='1.0' encoding='UTF-8' standalone='yes'?><html><head><meta http-equiv='Content-Type' content='text/html; charset=utf-8' ><script type='text/javascript'>function get_radio_value(test){ var elements = document.getElementsByName(test); for (var i=0; i < elements.length; i++){if (elements[i].checked){var rad_val = elements[i].value;return rad_val;}}}</script><title>Kundenfragebogen</title></head><body><h1>Kundenfragebogen</h1><form name='myForm' action=''><table border='2'><tr><td></td><td>sehr gut</td><td>gut</td><td>schlecht</td></tr><tr><td>Wie geht es Ihnen?</td><td><input type='radio' name='1' value='1'/>Mir ging es noch nie besser!</td><td><input type='radio' name='1' value='2'/>Es geht mir so wie immer.</td><td><input type='radio' name='1' value='3'/>Heute geht einfach gar nichts…</td></tr><tr><td>Können Sie Auto fahren?</td><td><input type='radio' name='2' value='1'/>Ja</td><td></td><td><input type='radio' name='2' value='3'/>Nein</td></tr><tr><td>Möchten Sie unseren Newsletter abonnieren?</td><td><input type='radio' name='3' value='1'/>Ja</td><td></td><td></td></tr></table></form></body></html>";
webbrowser.NavigateToString(f);

当我这样做时，WebBrowser只显示代码而不显示实际的HTML网站（使用RadioButtons，...）。当我这样做时：

string f = "\"<!DOCTYPE HTML PUBLIC ' -//W3C//DTD HTML 4.01 Transitional//EN' 'http://www.w3.org/TR/html4/loose.dtd'><?xml version='1.0' encoding='UTF-8' standalone='yes'?><html><head><meta http-equiv='Content-Type' content='text/html; charset=utf-8' ><script type='text/javascript'>function get_radio_value(test){ var elements = document.getElementsByName(test); for (var i=0; i < elements.length; i++){if (elements[i].checked){var rad_val = elements[i].value;return rad_val;}}}</script><title>Kundenfragebogen</title></head><body><h1>Kundenfragebogen</h1><form name='myForm' action=''><table border='2'><tr><td></td><td>sehr gut</td><td>gut</td><td>schlecht</td></tr><tr><td>Wie geht es Ihnen?</td><td><input type='radio' name='1' value='1'/>Mir ging es noch nie besser!</td><td><input type='radio' name='1' value='2'/>Es geht mir so wie immer.</td><td><input type='radio' name='1' value='3'/>Heute geht einfach gar nichts…</td></tr><tr><td>Können Sie Auto fahren?</td><td><input type='radio' name='2' value='1'/>Ja</td><td></td><td><input type='radio' name='2' value='3'/>Nein</td></tr><tr><td>Möchten Sie unseren Newsletter abonnieren?</td><td><input type='radio' name='3' value='1'/>Ja</td><td></td><td></td></tr></table></form></body></html>";
webbrowser.NavigateToString(f);

它工作正常！我只在开头设置\“。页面正在显示，但”正好在我的网站上。为什么f ...我必须在我的字符串开头写“html文件”吗？

编辑：这个更短，但同样的问题：

不工作：

string f = "<!DOCTYPE HTML PUBLIC '-//W3C//DTD HTML 4.01 Transitional//EN' 'http://www.w3.org/TR/html4/loose.dtd'><?xml version='1.0' encoding='UTF-8' standalone='yes'?><html><head><meta http-equiv='Content-Type' content='text/html; charset=utf-8' ><title>Kundenfragebogen</title></head><body><h1>Kundenfragebogen</h1>asdas</body></html>";
webbrowser.NavigateToString(f);

工作：

string f = "\"<!DOCTYPE HTML PUBLIC '-//W3C//DTD HTML 4.01 Transitional//EN' 'http://www.w3.org/TR/html4/loose.dtd'><?xml version='1.0' encoding='UTF-8' standalone='yes'?><html><head><meta http-equiv='Content-Type' content='text/html; charset=utf-8' ><title>Kundenfragebogen</title></head><body><h1>Kundenfragebogen</h1>asdas</body></html>";
webbrowser.NavigateToString(f);

Answer 1

我认为这是WP8中的一个错误，但有两种解决方法。一种方法是将HTML文件保存到独立存储中，并使用WebBrowser.Navigate()方法打开URI。如果使用该方法，则无需修改HTML文件。

另一种方法是删除顶部的声明（<!DOCTYPE HTML PUBLIC '-//W3C//DTD HTML 4.01 Transitional//EN' 'http://www.w3.org/TR/html4/loose.dtd'><?xml version='1.0' encoding='UTF-8' standalone='yes'?>），这样你的字符串就是

string f = "<html><head><meta http-equiv='Content-Type' content='text/html; charset=utf-8' ><script type='text/javascript'>function get_radio_value(test){ var elements = document.getElementsByName(test); for (var i=0; i < elements.length; i++){if (elements[i].checked){var rad_val = elements[i].value;return rad_val;}}}</script><title>Kundenfragebogen</title></head><body><h1>Kundenfragebogen</h1><form name='myForm' action=''><table border='2'><tr><td></td><td>sehr gut</td><td>gut</td><td>schlecht</td></tr><tr><td>Wie geht es Ihnen?</td><td><input type='radio' name='1' value='1'/>Mir ging es noch nie besser!</td><td><input type='radio' name='1' value='2'/>Es geht mir so wie immer.</td><td><input type='radio' name='1' value='3'/>Heute geht einfach gar nichts…</td></tr><tr><td>Können Sie Auto fahren?</td><td><input type='radio' name='2' value='1'/>Ja</td><td></td><td><input type='radio' name='2' value='3'/>Nein</td></tr><tr><td>Möchten Sie unseren Newsletter abonnieren?</td><td><input type='radio' name='3' value='1'/>Ja</td><td></td><td></td></tr></table></form></body></html>";
webbrowser.NavigateToString(f);
