I am writing a simple ftp client with c#.
I am not pro in c#. Is there any way to convert string to byte[] and write it to the socket?
for example for introducing username this is the socket content: 

5553455220736f726f7573680d0a

and ASCII equivalent is: 

USER soroush

I want a method to convert string. Something like this: 

public byte[] getByte(string str)
{
    byte[] ret;
    //some code here
    return ret;
}

Try

byte[] array = Encoding.ASCII.GetBytes(input);

// C# to convert a string to a byte array.
public static byte[] StrToByteArray(string str)
{
    Encoding encoding = Encoding.UTF8; //or below line
    //System.Text.UTF8Encoding  encoding=new System.Text.UTF8Encoding();
    return encoding.GetBytes(str);
}

and

// C# to convert a byte array to a string.
byte [] dBytes = ...
string str;
Encoding enc = Encoding.UTF8; //or below line 
//System.Text.UTF8Encoding enc = new System.Text.UTF8Encoding();
str = enc.GetString(dBytes);
