实际的单词“ListViewItem：”出现在我的ListView列中 [英] The actual words 'ListViewItem:' appearing in my ListView columns

问题描述

有人可以告诉我为什么我得到的单词ListViewItem：{ data here }in我的ListView SubItem列。换句话说，当我运行我的Win Forms应用程序时，在我的ListView的每一列中，我有数据的子项，实际的单词''ListViewItem ... ''出现在数据本身之前 - 用大括号显示。



直到我整理一些代码才发生这种情况。我希望这是一个简单的错误。



这是调用我的方法的代码。方法（或部分）显示在下面。

Hi,

Can anybody please tell me why i''m getting the words "ListViewItem: {data here}" in my ListView SubItem columns. In other words when i run my Win Forms application, in each column of my ListView where i have subItems of data, the actual words ''ListViewItem ...'' are appearing just before the data itself - which is displayed in curly braces.

This wasn''t happening until i was tidying some code up. I''m hoping it''s a simple mistake.

Here is the code which calls my method. And the method (or part of) is shown underneath.

// ListView1
            string[] checkedINfileList = Directory.GetFiles("O:\\TestDaws\\CSDB\\CheckedIN");
            
           foreach (string file in checkedINfileList)
            {
            
                ListViewItem itemName = list1.getName(file);
                ListViewItem itemSize = list1.getSize(file);
                ListViewItem itemModified = list1.getDate(file);
             
                listView1.Items.Add(itemName);
                itemName.SubItems.Add(itemSize.ToString() + " Kb");
                itemName.SubItems.Add(itemModified.ToString());

public ListViewItem getSize(string eachFile)
        {
            FileInfo f = new FileInfo(eachFile);
            long fileSize = f.Length;
            
            ListViewItem FileSize = new ListViewItem(fileSize.ToString());
            return FileSize;

推荐答案

因为这就是ListViewItem的默认ToString重写：打印类名为ListViewItem的后跟冒号，然后是大括号中的数据内容。

Because that is what the default ToString overridde of ListViewItem does: Prints the name ofg the class "ListViewItem" followed by a colon, and then the data content in curly brackets.

ListViewItem lvi = new ListViewItem("hello");
Console.WriteLine(lvi);

将打印

Will print

ListViewItem: {hello}

我假设您已删除了一个类派生自ListViewItem，并覆盖ToString以产生您想要的输出。

I assume that you have removed a class which derived from ListViewItem, and which overrode ToString to produce the output you wanted.
