What can System.Diagnostics.Process.Start(); do? It mainly has the following functions:
1. Open a link URL (popup window).
2. Locate and open a file directory.
3. Open the system special folder, such as "Control Panel".
(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"); //直接
call to open the file
(4) Process.Start (StringfileName, Stringarguments)
System.Diagnostics.Process.Start("explorer.exe", "D:\\Readme.txt"); //Open the file directly
Readme.txt
The method of opening a website with process.start() has been exemplified above. Now let’s talk about how to locate a file with processs.star()
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); //Locate and open D:\Program
Files\Tencent\QQ\Bin file directory and selected QQ.exe
Note: There is a comma (,) after /select.

This script is placed under the Editor folder. After the InitializeOnLoad feature is added, its construction method will be executed automatically. The test result is that every time the content of this class is modified, the construction method will be re-executed. You can perform some operations in the constructor to control the code execution in Editor mode.
Here I define an OnStart, and assign it to EditorApplication.update, the effect is similar to Mono's Start and Update methods.
The method defined by the InitializeOnLoadMethod attribute will also be executed after the construction method.
