Operation:

In C #, you can use the following methods:

Using system. diagnostics; // called when the namespace is called.

// We can use the following method in event processing:

Try

{

Process. Start ("[with the full name of the above file name]");

}

Catch (win32exception win32ex)

{

MessageBox. Show ("error cause:" + win32ex. message, "error", messageboxbuttons. OK, messageboxicon. Error );

}

Example:

Take Internet options as an example:

Let's modify the aboveCodeIs:

Using system. diagnostics;

Processstartinfo info = new processstartinfo ();

Try

{

Info. filename = "inetcpl. Cpl ";

Process. Start (Info );

}

Catch (win32exception win32ex)

{

MessageBox. Show ("error cause:" + win32ex. message, "error", messageboxbuttons. OK, messageboxicon. Error );

}

After running the program, the following results are displayed:

If we do not enter the complete file name in the program, an error will be generated with the following prompt:
