从类中填写列表视图

问题描述

大家好，首先我想说我只是在学习c＃。谷歌是我的朋友找到了我寻求的很多答案，这次我找不到答案。



我的表格中有通常的代码来加载listview。

Hi everyone, first I would like to say that I am just learning c#. Google is my friend in finding a lot of the answers that I seek, this time I cannot find the answer.

I have the usual code in my form to load a listview.

// main form
ListViewItem lView = new ListViewItem();
lView.Text = "Testing";
lView.SubItems.Add(Price);
lView.SubItems.Add(Manufacturer);
lView.SubItems.Add(InStock);
listView1.Items.Add(lView);

我想把它移到一个类，因为它会减少我的主程序中有很多代码。我的问题是我不知道如何在课堂上填写listview。我真的不知道如何指向列表视图，希望有人可以帮助我在这里。



这只是一个简化帖子的片段。 />

I want to move this to a class as it will cut down on a lot of code in my main program. My problem is I don't know how to fill the listview from within the class. I really don't know how to point to the listview, hope that someone can help me out here.

This is just a snippet to make posting simpler.

// class file
public void LoadListView(frmMain mainForm, string manufacturer, string Price, string InStock)
{
    ListViewItem lView = new ListViewItem();
    lView.Text = "Testing";
    lView.SubItems.Add(Price);
    lView.SubItems.Add(Manufacturer);
    lView.SubItems.Add(InStock);
    frmMain.listView1.Items.Add(lView);  // (right here the program doesn't know what ListView1 is)
}

// calling the class
WorkerClass workerClass = new WorkerClass();
workerClass.LoadListView(....);

感谢任何帮助。

Appreciate any help.

推荐答案

public class MyClass
   {
   ...
   public static void FillIt(ListView lv)
      {
      lv.Items.Add(...);
      ...
      }
   }

   ...
   MyClass.FillIt(listView1);
   ...

BTW：帮自己一个忙，并停止使用Visual Studio默认名称 - 你可能还记得TextBox8是今天的手机号码，但是当你需要修改它的时候是三周时间，那你呢？使用描述性名称 - 例如tbMobileNo - 您的代码变得更容易阅读，更自我记录，更易于维护 - 并且编码速度更快，因为Intellisense可以通过三次击键来tbMobile，其中TextBox8需要思考大概和8次击键......

BTW: Do yourself a favour, and stop using Visual Studio default names for everything - you may remember that "TextBox8" is the mobile number today, but when you have to modify it is three weeks time, will you then? Use descriptive names - "tbMobileNo" for example - and your code becomes easier to read, more self documenting, easier to maintain - and surprisingly quicker to code because Intellisense can get to to "tbMobile" in three keystrokes, where "TextBox8" takes thinking about and 8 keystrokes...
