The C # Process.Start () method is detailed

System.Diagnostics.Process.Start (); What can we do? It mainly has the following functions:

1. Open a link URL (pop-up window).

2. Locate and open a file directory.

3, open the System special folder, such as "Control Panel" and so on.

So how does it accomplish these functions? Before we talk about the application, let's take a look at the construction method of Process.star ().

Name Description
Process.Start () starts (or reuses) the process resource specified by the StartInfo property of this process component and

associated with the component.
Process.Start (ProcessStartInfo) starts the message that contains the process startup information (for example, the process to start

Name), and associate the resource with the new process component with the specified process resource.
Process.Start (String) starts a process resource by specifying the name of the document or application file, and the resource

Associated with the new Process component.
Process.Start (String, string) starts a process resource by specifying the name of the application and a set of command-line arguments

and associates the resource with the new Process component.
Process.Start (String, String, SecureString, String) by specifying the application name, user name, password

and domain to start a process resource and associate the resource with the new process component.
Process.Start (String, String, String, SecureString, String) by specifying the name of the application and a

Group command line arguments, user names, passwords, and domains to start a process resource and associate the resource with the new process component

To.


(1) Publicbool Start ()

System.Diagnostics.Process Process = new System.Diagnostics.Process ();

Process.   Startinfo.filename = "Iexplore.exe"; IE browser, can be replaced

Process. startinfo.arguments = "http://www.baidu.com";

Process. Start ();
(2) Publicstaticprocessstart (Processstartinfostartinfo)

System.Diagnostics.ProcessStartInfo ProcessStartInfo = new

System.Diagnostics.ProcessStartInfo ();

Processstartinfo.filename = "Explorer.exe"; Explorer

Processstartinfo.arguments = @ "D:\";

System.Diagnostics.Process.Start (ProcessStartInfo);
(3) Publicstaticprocessstart (stringfilename)

System.Diagnostics.Process.Start (@ "D:\Program files\tencent\qq\bin\qq.exe"); Direct

Call Open File


(4) Process.Start (Stringfilename, stringarguments)

System.Diagnostics.Process.Start ("Explorer.exe", "D:\\readme.txt"); Open file directly

Readme.txt
The example above already uses Process.Start () to open the Web site method, now talk about using Processs.star () to navigate to a file

Method.

This positioning method is similar to the search target on the shortcut://explorer/select, "D:\Program files\tencent

\qq\bin\qq.exe "

String path = @ "D:\Program Files\tencent\qq\bin\qq.exe";

System.Diagnostics.Process.Start ("Explorer.exe", "/select," +path); Positioning Open D:\Program

Files\tencent\qq\bin file directory and selected QQ.exe

Note: There is a comma (,) after the/select.


And then, by calling Rundll32.exe to open some system-specific files, let's briefly introduce the functions of the Rundll32.exe

and function.

As the name implies, Rundll32 is the "execute 32-bit DLL file", which is the execution of internal functions in the DLL file, you can use the command line

The form of a windows32-bit dynamic-link library is called.

Similarly, Rundll.exe is "executing a 16-bit DLL file" and invoking a 16-bit dynamic-link library. We pass

rundll32.exe executes instructions to accomplish some functions.
As an example:

System.Diagnostics.Process.Start ("Rundll32.exe", "user.exe,restartwindows"); System restart

SpecialFolder Enumeration Members:

Member name Description
The ApplicationData directory, which serves as the common repository for application-specific data for the current roaming user.

Roaming users work on more than one computer on the network. The roaming user's profile is saved on a network server when the user logs on

To a system, it is loaded into the system.
The Commonapplicationdata directory, which serves as a common repository for application-specific data that is used by all users.
CommonProgramFiles the directory for components that are shared among applications.
Cookies are used as directories for public repositories of Internet cookies.
Desktop logical desktops, not physical file system locations.
The desktopdirectory is used to physically store the directory of File objects on the desktop.

This directory should not be confused with the Desktop folder itself, which is a virtual folder.
Favorites a directory that serves as a common repository for user favorite items.
History the directory that is used as the public repository for Internet Chronicle items.
Internetcache is used as a directory for public repositories of temporary Internet files.
Localapplicationdata directory, which is used as the common storage for application-specific data that is not currently used by roaming users

Store.
MyComputer the "My Computer" folder.
Attention

Because the path is not defined for the My Computer folder, the MyComputer constant will always generate an empty string ("").
MyDocuments the "My Computer" folder.
MyMusic the "My Music" folder.
MyPictures the "My Pictures" folder.
Personal the directory that is used as a common repository for documents.
ProgramFiles the "Program Files" directory.
Programs contains a directory of user program groups.
Recent The directory that contains the documents that the user has recently used.
SendTo the directory containing the Send menu item.
StartMenu the directory containing the Start menu item.

These programs are started every time a user logs on, starts Windows NT or later, or starts Windows 98 o'clock

。
System "System" directory.
Templates a directory that is used as a common repository for document templates.

Through Environment.getfolderpath (Environment.SpecialFolder.XXXXX), we can easily get the department

And then use the Process.Start () method to open the folder.

For example:

System.Diagnostics.Process.Start (Environment.getfolderpath

(Environment.SpecialFolder.System)); Open System Folder (System32 folder)
