System.Diagnostics.Process Arguments

How can I pass Argument to the System.Dignostics.Process with spaces. I am doing this:

System.Diagnostics.Process proc = new System.Diagnostics.Process();
proc.EnableRaisingEvents = false;
proc.StartInfo.FileName = exePath + @"\bin\test.exe";

string args = String.Format(@"{0}{1}{2}{3}", "-plot " ,path1, " -o ", path2);
proc.StartInfo.Arguments = args;

when path1 and path2 do not contain spaces ( Let's say path1 = C:\Temp\ and path2 = C:\Temp\Test) then it works fine, but when path1 and path2 contain spaces for example path1 = C:\Documents and Settings\user\Desktop and path2 = C:\Documents and Settings\user\Desktop\New Folder) then it trucates the path1 and path2 and abort.

Please let me know the correct way for doing this.

Thanks, Ashish

Try the following:

string args = String.Format("{0}\"{1}\"{2}\"{3}\"", "-plot " ,path1, " -o ", path2);

This will put quotes around your paths so they are passed as a single string and spaces in them are ignored.

Process proc = new Process(); 
proc.EnableRaisingEvents = false; 
proc.StartInfo.FileName = Path.Combine(exePath, @"bin\test.exe");
proc.StartInfo.Arguments = String.Format(@"-plot ""{0}"" -o ""{1}""", path1, path2);

If using a literal (without @), you can escape the quotes:

\"{0}\"

If using a verbatim string (with @), you can double up your quotes:

""{0}""

put the paths in quotes... such as "\""+path1+"\""

you could put the arguments which may contain spaces in double quotes like so:

string args = String.Format(@"{0} ""{1}"" {2} ""{3}""", "-plot", path1, "-o", path2);

you need to encapsulate the path in quotes. Otherwise it reads the space as a delimiter and thinks the rest of the path is an argument.
