    text
    copied!<p>I am new to .bat files. I have a file containing these lines:</p> <pre><code>cd %~dp0 pat\to\dot.exe -Tsvg -o -Kdot %~n1.txt &gt; %~.svg </code></pre> <p>These lines will call <code>dot.exe</code> which will take the inputted text file and parse it into a .svg with some content. Currently I drag the .txt file on to the .bat with the code above to create the svg. I don't really know what <code>%~dp0</code> changes the directory to the current drive, I will have to move the file after I generate as well. I know <code>%~n1</code> represents the file path of the first argument.</p> <p>I want to run these two commands through c# using the command shell. the code below will generate the .svg file but it wont contain any data. I am assuming that is because the argument is not getting passed in correctly, but I am not really sure how to add it. Any suggestions?</p> <pre><code>[STAThread] static void Main() { string name = "file.txt"; ProcessStartInfo psi = new ProcessStartInfo(@"C:\WINDOWS\system32\cmd.exe"); psi.UseShellExecute = false; psi.ErrorDialog = false; psi.CreateNoWindow = true; psi.WindowStyle = ProcessWindowStyle.Hidden; psi.RedirectStandardError = true; psi.RedirectStandardInput = true; psi.RedirectStandardOutput = true; //I am not sure if this will actually attach the argument to the WriteLine() or not psi.Arguments = name; Process wgsProcess = new Process(); wgsProcess.StartInfo = psi; wgsProcess.Start(); StreamWriter inputWriter = wgsProcess.StandardInput; StreamReader outputReader = wgsProcess.StandardOutput; StreamReader errorReader = wgsProcess.StandardError; inputWriter.WriteLine("cd %~dp0"); inputWriter.Flush(); inputWriter.WriteLine(" pat\to\dot.exe -Tsvg - o - Kdot " + name + " &gt; " + name + ".svg"); inputWriter.Flush(); } </code></pre>
