Question

Trying to use ProcessStartInfo() to run batch in c#

Asked by: UnderSeven

This is pretty simple code I think, but it is returning that it can't find the file.  I'm not sure what I'm doing wrong, when I look at the path variable it LOOKs like I put it in right, but I'm not convinced.

pathvar = @"C:\Documents and Settings\jmatrone\Desktop\Projects\mergelistener\pdfcreator.bat ""C:\Documents and Settings\jmatrone\Desktop\Projects\mergelistener\service.ps"" ""C:\Documents and Settings\jmatrone\Desktop\Projects\mergelistener\service2.pdf""";
                    System.Diagnostics.ProcessStartInfo p = new System.Diagnostics.ProcessStartInfo(pathvar);
                    System.Diagnostics.Process proc = new System.Diagnostics.Process();
                    proc.StartInfo = p;
 
                    proc.Start();
                    proc.WaitForExit();

Try passing the arguments to your batch file in the following manner:

string pathvar = @"C:\Documents and Settings\jmatrone\Desktop\Projects\mergelistener\pdfcreator.bat";
string args = @"C:\Documents and Settings\jmatrone\Desktop\Projects\mergelistener\service.ps C:\Documents and Settings\jmatrone\Desktop\Projects\mergelistener\service2.pdf";
System.Diagnostics.ProcessStartInfo p = new System.Diagnostics.ProcessStartInfo(pathvar, arg);
System.Diagnostics.Process proc = new System.Diagnostics.Process();
proc.StartInfo = p;
 
proc.Start();
proc.WaitForExit();

The Process and ProcessStartInfo expect that arguments and application to be seperate.

I would do args like such though.

string arg1 = @"C:\Documents and Settings\jmatrone\Desktop\Projects\mergelistener\service.ps";
string arg2 = @"C:\Documents and Settings\jmatrone\Desktop\Projects\mergelistener\service2.pdf";
string args = "\"" + arg1 + "\" \"" + arg2 + "\"";

This should ensure that they get treated as 2 arguments rather then getting accidently split on the space chars in document and settings.  When in doubt can always make a quick console application and pipe your date into it to verify the call is going out correctly.

Yep.  I wonder why it couldn't handle it in a single string, but whatever.
