Whats wrong with system.diagnostics

[makdu]

i want to delete file.txt

 System.Diagnostics.Process.Start("cmd.exe", @"/c del  d:\\file.txt");

but this is not deleting the file. any input?

[memeloo]

and if you run this command alone, does it work?

also check the exit code

System.Diagnostics.Process.ExitCode

Why to do it in such a obscure way? Ins't File.Delete better?

Why to do it in such a obscure way?

for fun? to learn something new?

[boudino]

Maybe new forum could be established: toy fixing

[makdu]

this is my complete code

System.Diagnostics.Process.Start("cmd.exe", @"/c route print > d:\file.txt"); // Get the route print to text file
            StreamReader streamReader = new StreamReader(filePath);
            string readtext = streamReader.ReadToEnd();
            streamReader.Close();
 System.IO.File.Delete("d:\file.txt"); //Delete the  output dump file

But i am getting error in the stream reader(filepath)

Could not find file 'd:\file.txt'..

the File is getting genereated

i have started to do coing in c# just 4 days back. I want to get the route print command to be executed and get that to a file . So when i searched some forum, i got the reply to do with

System.Diagnostics.Process.Start

To delete also , i was trying the same way. i was not aware of the other option available. Now i moved code to file.delete . thanks for the help on that .
Is there a way i can run the command prompt from the c# other than what i have done using System.Diagnostics.Process.Start

No.

The file is not getting deleted

 System.Diagnostics.Process.Start("cmd.exe", @"/c route print > d:\file.txt"); // Get the route print to text file
            using (StreamReader streamReader = File.OpenText(filePath))
            {

                string s = "";
                if ((s = streamReader.ReadLine()) != null)
                {
                    readtext = streamReader.ReadToEnd();// streamReader.ReadToEnd();

                }
            }



            /* delete all unwanted files */
           
                System.IO.File.Delete("d:\\file.txt"); //Delete the  output dump file

also at first time rum ( after manually deleting the file.txt) , i am getting file not found error at

using (StreamReader streamReader = File.OpenText(filePath))

hERE IS my Complete code. This code some times work proplery by reading and writing ( when there is a breakpoint), some times it is not working

            }
            deletefiles();
        }
       }

Is it something to do with the timer?

[memeloo]

try to call

System.Diagnostics.Process.WaitForExit();

right after

System.Diagnostics.Process.Start("cmd.exe", @"/c route print > d:\file.txt"); // Get the route print to text file
System.Diagnostics.Process.WaitForExit()
