Restore MySQL DB through C#

I try to backup and restore MySQL database from C# using process.
 
First BackUP:
the command to backup database is :
-u USER -pPASS --databases DATABASE -r > path/to/file.sql
Here is my C# code:

Process.Start(@"C:\Program Files\MySQL\MySQL Server 5.5\bin\mysqldump.exe", ("-u user -p***** --databases DB -r \"" + path + "\"";

Look at the difference, in my code is not ">", becuse it wont work with it. If I put this char to code, it just show me usage of mysqldump in win cmd. Without it, this code work good.
 
Now i want to restore database.
the command to restore database is :
-u USER -pPASS DATABASE < path/to/file.sql
Here is my c# codes :
 
1#

Process.Start(@"C:\Program Files\MySQL\MySQL Server 5.5\bin\mysql.exe", ("-u user -p**** < \"" + path + "\""));

 
2#

            Process myProcess = new Process();
            myProcess.StartInfo.FileName = @"C:\Program Files\MySQL\MySQL Server 5.5\bin\mysql.exe";
            myProcess.StartInfo.UseShellExecute = false;
            myProcess.StartInfo.WorkingDirectory = @"C:\Program Files\MySQL\MySQL Server 5.5\bin\";
            myProcess.StartInfo.Arguments = "-u user -p**** PIEx < + "\"" + path + "\"";
            myProcess.StartInfo.RedirectStandardInput = false;
            myProcess.StartInfo.RedirectStandardOutput = false;
            myProcess.Start();
 
            myProcess.WaitForExit();
            myProcess.Close();

 
Both solutions dont work. I think it is becuse of this char ">", the same problem like backup, but in this case, removing it dont work. The result is same, it write down mysql usages in cmd console.
 
If I execute this commands manually in cmd (move to mysql bin, then run mysql with arguments), it work fine. I try redirect output/input/error to stream readers/writers - not work. Try to UseShellExecute = true - not work. Nothing works.
 
Help me guys. Thx
