You cannot define a command line on several lines. It has to be continuous.

C#

using (StreamWriter sw = new StreamWriter(batFilePath))
{
   sw.Write("mysql -u techu -p");  //techu is username 
   sw.Write("12341234");   // password
   sw.WriteLine(" < H:\testscript.sql");
   sw.WriteLine("@echo done");
   //sw.WriteLine("pause");
}

if we write "mysql -u techu -p" in command prompt, in next step it prompts to enter password. if password is correct it enters to mysql mode. then if we enter "source<space> path/of/sqlscript then it executes that sql script file.
Here what is happening is, it is not taking password because sw.writeline is giving password as a new command. at that step it is failing to execute.

password option[^]
If you provide the password on the command line, it will not be prompted.
