listview的子项被添加到下一行。为什么？ [英] Sub items of listview gets added to next row.Why?

问题描述

我创建了一个Listview并且可以添加子项。我的问题是当我从文本文件导入数据时，子项被添加到下一行。我正在使用Filehelpers

这是代码

I created a Listview and can add sub items.My problem is when I import data from a text file the sub items are added onto the next row.I am using Filehelpers
This is the code

listView1.Items.Clear();
        
        FileHelperEngine engine = new FileHelperEngine(typeof(AutoDetectedClass));
        AutoDetectedClass[] result = (AutoDetectedClass[])engine.ReadFile(selectedFileName);

        foreach (AutoDetectedClass row in result)
        {
            ListViewItem lstItem = new ListViewItem();
            listView1.Items.Add(row.PIN.ToString());
            lstItem.SubItems.Add(row.DateTime.ToString());
            lstItem.SubItems.Add(row.DeviceNumber);
            lstItem.SubItems.Add(row.CheckState);
            lstItem.SubItems.Add(row.Verify);
            lstItem.SubItems.Add(row.WorkCode);
            listView1.Items.Add(lstItem);



             }

任何帮助都将受到赞赏

Any help would be appreciated

推荐答案

你犯的错误是添加两个新项目。

一旦进入行 listView1.Items.Add（row.PIN.ToString（））

和一行 listView1.Items.Add（lstItem）



更改代码如下：

The mistake you have made is to add two new items.
Once in the line listView1.Items.Add(row.PIN.ToString())
and once in the line listView1.Items.Add(lstItem)

Change the code as below:

listView1.Items.Clear();
        
FileHelperEngine engine = new FileHelperEngine(typeof(AutoDetectedClass));
AutoDetectedClass[] result = (AutoDetectedClass[])engine.ReadFile(selectedFileName);
 
foreach (AutoDetectedClass row in result)
{
    ListViewItem lstItem = new ListViewItem();
    ListViewItem lstItem = listView1.Items.Add(row.PIN.ToString());
    lstItem.SubItems.Add(row.DateTime.ToString());
    lstItem.SubItems.Add(row.DeviceNumber);
    lstItem.SubItems.Add(row.CheckState);
    lstItem.SubItems.Add(row.Verify);
    lstItem.SubItems.Add(row.WorkCode);
    listView1.Items.Add(lstItem);
}
