winform中讀取嵌入的xml檔案

 System.Reflection.Assembly thisExe = System.Reflection.Assembly.GetExecutingAssembly();
string xmlPath = string.Empty; 
xmlPath = "AutoCode.BLL.xml";// "名稱空間.檔案名稱.xml" 注意xml必須放到項目的根目錄，放入檔案夾裡無效。記得xml檔案要是utf-8編碼
 System.IO.Stream xmlr = thisExe.GetManifestResourceStream(xmlPath);
StreamReader sr = new StreamReader(xslr,Encoding.UTF8);

string str= sr.ReadToEnd();

File.Delete("temp.xml");
File.AppendAllText("temp.xml", str, Encoding.UTF8);//寫到xml檔案
