Use BinaryWriter to write the file the first character is garbled what is the reason?

Try
{
   FileStream myfs = new FileStream (filepath + @ "\patchmove.ini", FileMode.Create);
   BinaryWriter MYBW = new BinaryWriter (MYFS);
   Mybw.write ("The Valley of the E:\ Dragon");
   Mybw.close ();
   Myfs.close ();
}
catch (Exception) {}

The code is like this

Well, that's what the paper says.

The first garbled in the end how to come to think Impassability

There are two solutions:

Methods one, using StreamWriter

Try
 {
    FileStream myfs = new FileStream (filepath + @ "\patchmove.ini", FileMode.Create);
    <span style= "Color:rgb (51, 51, 51); Font-family:helvetica, Tahoma, Arial, Sans-serif; font-size:14px; line-height:24px; Background-color:rgb (245, 245, 245); >STREAMWRITER</SPAN>MYBW = new <span style= "Color:rgb" (51, 51, 51); Font-family:helvetica, Tahoma, Arial, Sans-serif; font-size:14px; line-height:24px; Background-color:rgb (245, 245, 245); >StreamWriter</span> (MYFS);
    Mybw.write (<span style= "Font-family:helvetica, Tahoma, Arial, Sans-serif;" > "e:\ Dragon Valley" </span>);
    Mybw.close ();
    Myfs.close ();
}
catch (Exception) {}

Method Two, change to Mybw.write (path. ToCharArray ());

Try
{
   FileStream myfs = new FileStream (filepath + @ "\patchmove.ini", FileMode.Create);
   <span style= "Font-family:helvetica, Tahoma, Arial, Sans-serif; Background-color:rgb (245, 245, 245); >STREAMWRITER</SPAN>MYBW = new <span style= "Font-family:helvetica, Tahoma, Arial, Sans-serif; Background-color:rgb (245, 245, 245); >StreamWriter</span> (MYFS);
   Mybw.write (<span style= "Color:rgb" (Wuyi, Wuyi); Font-family:helvetica, Tahoma, Arial, Sans-serif; font-size:14px; Lin e-height:24px; Background-color:rgb (245, 245, 245); > "E:\ the Valley of the Dragon". ToCharArray () </span>);
   Mybw.close ();
   Myfs.close ();
}
catch (Exception) {}
