项目发布打包-C#winform项目制作安装包想把mysql数据库一起附加进去，调用cmd执行脚本无效，求助

                string dbname = this.Context.Parameters["dbname"];//数据库名称                string server = this.Context.Parameters["server"];//服务器名称                string uid = this.Context.Parameters["user"];//SQlServer用户名                string pwd = this.Context.Parameters["pwd"];//密码                string path = this.Context.Parameters["targetdir"];//安装目录                String appDirecroty = "C:\\Program Files\\MySQL\\MySQL Server 5.6\\bin\\";                StringBuilder sbcommand = new StringBuilder();                string directory = path + "database" + "\\" + "121www.sql";                sbcommand.AppendFormat("mysql -uroot -p123456 121www <{0}", directory);                String command = sbcommand.ToString();                //MessageBox.Show(command);                Cmd.StartCmd(appDirecroty, command);

Cmd中是这样写的
public class Cmd
{
///
/// 执行Cmd命令
///
/// 要启动的进程的目录
/// 要执行的命令
public static void StartCmd(String workingDirectory, String command)
{
Process p = new Process();
p.StartInfo.FileName = "cmd.exe";
//MessageBox.Show(p.StartInfo.WorkingDirectory);
p.StartInfo.WorkingDirectory = workingDirectory;
//MessageBox.Show(p.StartInfo.WorkingDirectory);
p.StartInfo.UseShellExecute = false;
p.StartInfo.RedirectStandardInput = true;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.RedirectStandardError = true;
p.StartInfo.CreateNoWindow = true;
p.Start();
p.StandardInput.WriteLine(command);
//MessageBox.Show(command);
p.StandardInput.WriteLine("exit");
}
