Running batch file with arguments from C#

Question

I have a batch file like this

@echo off
xcopy /e %1 %2

I have my C# code as follows:

string MyBatchFile = @"C:\Program Files (x86)\MybatchFile.bat";
string _sourcePath = @"C:\FolderToCopy";
string _tempTargetPath = @"C:\TargetFolder\";

var process = new Process { 
                   StartInfo = { 
                      Arguments = string.Format("{0} {1}",
                                                _sourcePath,
                                                _tempTargetPath) 
                                } 
                          };
process.StartInfo.FileName = MyBatchFile;
bool b = process.Start();

I expect this to copy the source files to target location. But nothing happens. My console window also does not stay for enough time so that I can see the error. Can anyone guide to achieve this. I am new in batch files processing.

Edit

By adding a pause in the end of batch file. Able to reproduce error. Getting error as

Files not found - Program

Running batch file directly does work fine. Just now noticed......when source path has any spaces....I am getting error

Answer 1

What about quoting argument?

Arguments = String.Format("\"{0}\" \"{1}\"", _sourcePath, _tempTargetPath) …

Answer 2

try

string MyBatchFile = @"C:\MybatchFile.bat";
string _sourcePath = @"C:\FolderToCopy\*.*";
string _tempTargetPath = @"C:\TargetFolder\";

i.e. add *.* to the source path

and add a 3rd line pause to the batch file

@echo off
copy /e %1 %2
pause

.bat file is a text file, in order to execute it, you should start cmd process. Start it like this:

System.Diagnostics.Process.Start("cmd.exe", "/c yourbatch.bat");

Additional arguments may follow. Try this without c#, in a cmd window, or Run dialog.
