running dos command line from C#?

I am trying to run this command from command-line prompt:

"D:\\fiji\\fiji.exe -macro D:\\fiji\\macros\\FFTBatch.ijm --headless"

It works perfect when I type it in a command-line console.

However, when I was trying to make it work from C# application, it failed. I tried following, but seems the command above did not get executed somehow:

string fijiCmdText = "D:\\fiji\\fiji.exe -macro D:\\fiji\\macros\\FFTBatch.ijm --headless";
System.Diagnostics.Process.Start("cmd.exe", fijiCmdText);

Anyone has any idea how to change it to work? Thanks.

The problem was solved in the direction Chris Haas pointed out. Simply adding "/C " in front of the path, and it worked for me:

Original code that did not work:

string fijiCmdText = "D:\\fiji\\fiji.exe -macro D:\\fiji\\macros\\FFTBatch.ijm --headless";
System.Diagnostics.Process.Start("cmd.exe", fijiCmdText)

The code that works:

string fijiCmdText = "/C D:\\fiji\\fiji.exe -macro D:\\fiji\\macros\\FFTBatch.ijm --headless";
System.Diagnostics.Process.Start("cmd.exe", fijiCmdText);

Here is the reference mentioned by Chris Haas. See EDIT3

You don't have to run cmd.exe, just create ProcessStartInfo object and pass the command with its parameters to it. Like this:

System.Diagnostics.ProcessStartInfo info = new System.Diagnostics.ProcessStartInfo("your command", "parameters");

Here is an example that shows you how to do it:

System.Diagnostics.ProcessStartInfo info = new System.Diagnostics.ProcessStartInfo("tree.com", "/f /a");
System.Diagnostics.Process p = new System.Diagnostics.Process();
p.StartInfo = info;
p.Start();
p.WaitForExit();

So in your case, this is your command: "D:\\fiji\\fiji.exe" and this is your command parameters or arguments: @"-macro D:\\fiji\\macros\\FFTBatch.ijm --headless"

Try This:

ProcessStartInfo info = new ProcessStartInfo(@"D:\fiji\fiji.exe",@"-macro D:\fiji\macros\FFTBatch.ijm --headless");
Process process = new Process();
process.StartInfo = info;
process.Start();
