C # detailed description of Process. Start () method

System. Diagnostics. Process. Start (); what can be done? It provides the following functions:

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

2. Locate and open a file directory.

3. Open special system folders, such as "Control Panel.

So how does it implement these functions? Before talking about the application, let's take a look at the construction method of Process. Star.

 

Name	Description
Process. Start ()	Start (or reuse) The Process resource specified by the StartInfo attribute of this Process component and associate it with this component.
Process. Start (ProcessStartInfo)	Start the Process resource specified by the parameter that contains the Process startup information (for example, the name of the Process to be started) and associate the resource with the new Process component.
Process. Start (String)	You can specify the name of a document or application file to start the Process resource and associate the resource with the new Process component.
Process. Start (String, String)	You can specify an application name and a set of command line parameters to start a Process resource and associate the resource with the new Process component.
Process. Start (String, String, SecureString, String)	Start a Process resource by specifying the application name, user name, password, and domain, and associate the resource with the new Process component.
Process. Start (String, SecureString, String)	You can specify an application name and a group of command line parameters, user names, passwords, and domains to start a Process resource and associate the resource with the new Process component.

(1) publicbool Start ()

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

Process. StartInfo. FileName = "iexplore.exe"; // IE browser, which can be changed

Process. StartInfo. Arguments = "http://www.baidu.com ";

Process. Start ();

(2) publicstaticProcessStart
(ProcessStartInfostartInfo)

System. Diagnostics. ProcessStartInfo processStartInfo = new System. Diagnostics. ProcessStartInfo ();

ProcessStartInfo. FileName = "assumer.exe"; // Resource Manager

ProcessStartInfo. Arguments = @ "D :\";

System. Diagnostics. Process. Start (processStartInfo );

(3) publicstaticProcessStart
(StringfileName)

System. Diagnostics. Process. Start (@ "D: \ Program Files \ Tencent \ QQ \ Bin \ QQ.exe"); // directly call to open the file

(4) Process. Start (StringfileName,
Stringarguments)

System. Diagnostics. Process. Start ("assumer.exe", "D: \ Readme.txt"); // open the Readme.txt file directly.

The preceding example shows how to use process. start () to open a website. Now let's talk about how to use processs. star () to locate a file.

This method is similar to the search target in 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 ("assumer.exe", "/select," + path); // open the D: \ Program Files \ Tencent \ QQ \ binfile directory and select qq.exe

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

The following is a simple introduction to the functions and functions of rundll32.exe.

As the name implies, rundll32 is the "32-bit dll file execution", that is, the internal function in the dll file execution. It can call the dynamic link library of Windows 32-bit in the form of a command line.

Likewise, rundll.exe is "executing 16-bit dll files" and calls a 16-bit dynamic link library. We use rundll32.exe to execute commands to complete some functions.

For example:

System. Diagnostics. Process. Start ("rundll32.exe", "user.exe, restartwindows"); // System restart command
