I have a wierd problem running a process. pls have a look at this .

Hello Guys, I am trying to run MSDOS fc.exe file using a process in C#. I have write down the following codes. I have also redirect the process's output so that i can read the output. The problem is when i run the program the following line of code suppose to return the output to the string s. s=proc.StandardOutput.ReadToEnd().ToString(); But it didn't return. But the wired thing is when i debug the program it works fine. i have no idea where is the problem the code is : string s="ABBFHFF"; string workDir=@"C:\Test Projects\Accumulator"; System.Diagnostics.Process proc = new System.Diagnostics.Process(); proc.StartInfo.UseShellExecute=false; //proc.EnableRaisingEvents=false; proc.StartInfo.WorkingDirectory=workDir; proc.StartInfo.FileName=@"fc"; proc.StartInfo.Arguments=@"C:\acc.xml C:\output.txt"; proc.StartInfo.WindowStyle=ProcessWindowStyle.Normal; proc.StartInfo.RedirectStandardOutput=true; try { //StreamReader sr=proc.StandardOutput; proc.Start(); s=proc.StandardOutput.ReadToEnd().ToString(); MessageBox.Show(s); MessageBox.Show(proc.StandardOutput.ReadToEnd()); proc.WaitForExit(); //MessageBox.Show(sr.ReadToEnd()); //sr.Close(); } catch(Exception ex) { MessageBox.Show(ex.ToString()); } MessageBox.Show(s.ToString()); For your kind informations fc is a dos program for comparing the content of the files. usually found in WIndows\System32 directory Thanks
