C # Online English-Chinese dictionary applet _c# tutorial for Beginners

Today wrote an English-Chinese dictionary applet, I added a lot of comments, suitable for beginners to refer to, where the bad writing please help point out, learning progress together.
Here is a generic, generic dictionary, manipulation of some controls, application of split, application of arrays, time intervals, use of LinkLabel.

Using System.Collections.Generic;
Using System.ComponentModel;

Using System.Windows.Forms;

Using System.IO;
    Namespace the final version of the English-Chinese dictionary {public partial class Form1:form {public Form1 () {InitializeComponent (); //The first step, I was first to the English-Chinese dictionary txt data source content storage, easy to use//first, use a generic dictionary to store English-Chinese dictionaries. TXT content//Introspection dictionary is (dictionary<,>) such, inside is the key value pairs//each row of data must have a unique key can not be repeated, the trailing data can be repeated//new a generic dictionary dictionary&lt
    ; string, string> dic = new dictionary<string, string> ();

    New A generic list list<string> list = new list<string> (); Read an English-Chinese dictionary. TXT file, it is necessary to know its path//My personal suggestion is to put the English-Chinese dictionary. txt file in a relative path, because after packaging easy to use//the absolute path to read the file//Plus @, easy to follow the symbolic conversion//encoding.default is the choice when
    Previous system default font encoding//string[] Strarr = File.ReadAllLines (@ "C:\Users\Administrator\Desktop\ English-Chinese dictionary. txt", encoding.default); Read the file on the relative path//I chose the relative path string[] Strarr = File.ReadAllLines (@ "English-Chinese dictionary. txt", encoding.default);

    Automatically run the private void Form1_Load (object sender, EventArgs e) {stime () when the form is loaded; Label2.

      Text = "The result of your query:"; Iterate through each row, each row is two elements, English and Chinese for (int i = 0; i < Strarr. Length; i++) {//Remove a single null character string[] strarr1 = Strarr[i using the Split method.
        Split (new char[] {'}, stringsplitoptions.removeemptyentries); Avoid repeating add//contains is included meaning if (!dic).
          Keys.contains (Strarr1[0]) {//In fact, this is OK, but as a rigorous programmer, I would like to add a judgment//to the array of English and Chinese into the generic dictionary Dic.
          ADD (Strarr1[0], strarr1[1]); Add English to the generic list the data in this list is the key value list within DIC.
        ADD (Strarr1[0]); }//In order to allow the program to run up the thought can be tall some, fill out this code autocompletestringcollection strings = new Autocompletestringcollectio
