Webbrowser中显示MHT文件

把MHT文件存成临时文件，用WEBBROWSER的Navigate方法打开，代码如下:

//从程序集中读取资源文件

Assembly asmm = Assembly.GetCallingAssembly();

Assembly asm = Assembly.ReflectionOnlyLoadFrom(AddInfo.HTMLAssembly);
Stream str=asm.GetManifestResourceStream(AddInfo.HTMLNavigationFile);

if (str == null)
return false;

//保存成临时文件

string vFilePath=AppDomain.CurrentDomain.BaseDirectory + "Temp";
string vFileName =vFilePath + "\index.mht";//我资源文件里面的MHT文件

if (Directory.Exists(vFilePath) == false)
Directory.CreateDirectory(vFilePath);

if (File.Exists(vFileName))
File.Delete(vFileName);

StreamReader sr = new StreamReader(str);
StreamWriter sw = new StreamWriter(vFileName);

sw.Write(sr.ReadToEnd());
sw.Flush();
sw.Close();
sr.Close();

//webbrowser加载

wbNavigation.Navigate("file://"+vFileName);
while (wbNavigation.ReadyState != WebBrowserReadyState.Complete)
{
     Application.DoEvents();
}
