Question

UPDATED…

I want to call kdiff from Console application. So I’m building two files and want to compare they at the end of executing my program:

string diffCmd = string.Format("{0} {1}", Logging.FileNames[0], Logging.FileNames[1]);
// diffCmd = D:\vdenisenko\DbHelper\DbHelper\bin\Debug\Reports\16_Nov 06_30_46_DiscussionThreads_ORIGIN.txt D:\vdenisenko\DbHelper\DbHelper\bin\Debug\Reports\16_Nov 06_30_46_DiscussionThreads_ORIGIN.txt
System.Diagnostics.Process.Start(@"C:\Program Files (x86)\KDiff3\kdiff3.exe", diffCmd);

//specification is here http://kdiff3.sourceforge.net/doc/documentation.html

It runs kdiff3 tool, but something wrong with filenames or command… Could you please look on screenshot and say what is wrong?

Answer 1

You need to use Process.Start():

string kdiffPath = @"c:\Program Files\Kdiff3.exe"; // here is full path to kdiff utility
string fileName = @"d:\file1.txt";
string fileName2 = @"d:\file2.txt";

Process.Start(kdiffPath,String.Format("\"{0}\" \"{1}\"",fileName,fileName2));

Arguments as described in the docs: kdiff3 file1 file2
