run prompt command with multiple parts

[wolf99]

Hi Folks

At a last attempt to integrate some SSH functionality I'd like to be able to run the prompt command

echo myString | C:\plink.exe testProfile -l userName

now I can get the later part ok with:

System.Diagnostics.Process.Start("echo 5| c:\lantronix\plink.exe", "test2 -l admin")

but how can I put the echo myString part?
Doesn't matter if its ugly, its just to automate test so we can easily change the values of myString

Cheers
