Gets or sets a value indicating whether to use the operating system shell to start the process.
Assembly: System (in System.dll)
Setting this property to false enables you to redirect input, output, and error streams.
When you use the operating system shell to start processes, you can start any document (which is any registered file type associated with an executable that has a default open action) and perform operations on the file, such as printing, by using the Process object. When is false, you can start only executables by using the Process object.
must be true if you set the ErrorDialog property to true.
The WorkingDirectory property behaves differently depending on the value of the property. When is true, the WorkingDirectory property specifies the location of the executable. If WorkingDirectory is an empty string, it is assumed that the current directory contains the executable.
When is false, the WorkingDirectory property is not used to find the executable. Instead, it is used only by the process that is started and has meaning only within the context of the new process. When is false, the FileName property must be a fully qualified path to the executable.
Process compiler = new Process(); compiler.StartInfo.FileName = "csc.exe"; compiler.StartInfo.Arguments = "/r:System.dll /out:sample.exe stdstr.cs"; compiler.StartInfo.UseShellExecute = false; compiler.StartInfo.RedirectStandardOutput = true; compiler.Start(); Console.WriteLine(compiler.StandardOutput.ReadToEnd()); compiler.WaitForExit();
