            進(jìn)程 Process的使用

            1 Process?
            ? 簡(jiǎn)單實(shí)例:

            // ?Execute?notepad.exe?with?no?command-line?arguments.
            Process.Start( " notepad.exe " );

            // ?Execute?notepad.exe?passing?the?name?of?the?file?to?open?as?a?
            // ?command-line?argument.
            Process.Start( " notepad.exe " ,? " SomeFile.txt " );

            Properties of the ProcessStartInfo Class

            Property

            Description

            Arguments

            The command-line arguments to pass to the new process.

            ErrorDialog

            If Process.Start can't start the specified process, it will throw a System.ComponentModel.Win32Exception. If ErrorDialog is true, Start displays an error dialog to the user before throwing the exception.

            FileName

            The name of the application to start. You can also specify any type of file for which you have configured an application association. For example, you could specify a file with a .doc or .xls extension, which would cause Microsoft Word or Microsoft Excel to run.

            WindowStyle

            A member of the System.Diagnostics.ProcessWindowStyle enumeration, which controls how the window is displayed. Valid values include Hidden, Maximized, Minimized, and Normal.

            WorkingDirectory

            The fully qualified name of the initial directory for the new process.


            進(jìn)程的啟動(dòng):

            The following example uses Process to execute Notepad in a maximized window and open a file named C:\Temp\file.txt. After creation, the example calls the Process.WaitForExit method, which blocks the calling thread until a process terminates or a specified time-out expires.


            using?System;
            using?System.Diagnostics;

            Methods for Obtaining Process References

            Method

            Description

            GetCurrentProcess

            Returns a Process object representing the currently active process.

            GetProcessById

            Returns a Process object representing the process with the specified ID.

            GetProcesses

            Returns an array of Process objects representing all currently active processes.

            GetProcessesByName

            Returns an array of Process objects representing all currently active processes with a specified friendly name. The friendly name is the name of the executable excluding file extension or path; for example, notepad or calc.

            The following example starts a new instance of Notepad, waits five seconds, and then terminates the Notepad process. The example first tries to terminate the process using CloseMainWindow. If CloseMainWindow returns false, or the Notepad process is still running after CloseMainWindow is called, the example calls Kill and forces the Notepad process to terminate; you can force CloseMainWindow to return false by leaving the File Open dialog box open.

            using?System;
            using?System.Threading;
            using?System.Diagnostics;

            ????????????????????process.Kill();
            ????????????????}

            ????????????}

            ????????}


            ????????
