Liam's C # learning Journey (vii): WPF (Windows Presentation Foundation), Windows Form applications

In today's class, the teacher tells us about some of the WPF (Windows Presentation Foundation) and Windows Form applications, so let's review it together:

(i), WPF (Windows Presentation Foundation):

WPF is an important application for desktop mobile phone development. It uses a variant of the XML Language--xaml language (extensible Application Markup Language).

With XAML developers, all user interface elements of a WPF program, such as text, buttons, images, list boxes, and so on, can be set up in detail, while the entire interface can be rationalized for layout, much like using HTML. However, because XAML is XML-based, it is itself a well-organized XML document, and its syntax is more rigorous and unambiguous relative to HTML. It is expected that most of the XAML will be automatically generated by the corresponding software, just as we are now making a static page with almost no HTML code to produce an aesthetically pleasing page directly from the Dreamweaver software.

In the extracurricular, I again through Bob Tabor's C # teaching video, more in-depth study of some of the XAML program, through these video explanation, we can understand more deeply understanding, below is a simple example and its output result:

Output Result:

　　

(b), Windows Form applications:

In fact, before the teacher to explain this chapter, we are writing crc_generation in the use of this aspect of the content, let me through this program to review the relevant content:

I wrote the following code:

usingSystem;usingSystem.Collections.Generic;usingSystem.ComponentModel;usingSystem.Data;usingSystem.Drawing;usingSystem.Linq;usingSystem.Text;usingSystem.Threading.Tasks;usingSystem.Windows.Forms;namespacecrc_generation_form{ Public Partial classForm1:form { PublicForm1 () {InitializeComponent (); Registerbox.readonly=true; }        Private voidokButton_Click (Objectsender, EventArgs e) {System.Diagnostics.Process P=NewSystem.Diagnostics.Process (); stringDebugaddress =environment.currentdirectory; p.StartInfo.FileName= Debugaddress +"\\CRC_Generation.exe"; P.startinfo.useshellexecute=false; P.startinfo.createnowindow=true; P.startinfo.arguments=Pathbox.text; P.startinfo.redirectstandardoutput=true; P.startinfo.redirectstandarderror=true; P.startinfo.redirectstandardinput=true;            P.start ();            OUTPUTBOX.ITEMS.ADD (P.standardoutput.readtoend ()); //pathbox.value = "";         }    }}

This is mainly the Ok_button of the Click event to write the content, through the process statement with the external pre-written console program connected, and the output is redirected to the Outputbox in the form, the output is as follows:

(Error input)

(correct input)
