在WPF应用程序中将项目添加到C#中的ListView中 [英] Adding items to a ListView in C# in a WPF application

问题描述

我想在磁盘上创建文件列表视图，以便在选择后进行进一步处理.因此，我使用列文件名，日期和大小创建了一个列表视图.然后，我使用以下函数加载listview:

I want to create a listview of files on the disk for further processing when selected. So I created a listview with the columns filename, date, and size. I then load the listview with the following function:

private void Window_Loaded(object sender, RoutedEventArgs e)  
{  
    foreach (string s in Directory.GetLogicalDrives())  
    {  
        filelist.Items.Add(s);   
    }  
}  

这列出了系统中要启动的驱动器，这很好，但是屏幕上显示的是

This lists the drives in the system to start which is fine, but what shows up on screen is

filename date size  
c:\      c:\  c:\  
d:\      d:\  d:\

所以，我的问题是，如何将子列的日期和大小设置为" 或" ?

So, my question is, how to I set subcolumns date and size to "" or " "?

推荐答案

您似乎有很多东西要学习，所以我只给您一些提示以帮助您入门，因为否则答案会太长.

You seem to have much to learn, so I'll just give you some clues to get you started, because otherwise this answer will be too long.

您有3列，每列都是从同一对象(字符串)获取数据.

You have 3 columns and each one is getting its data from the same object (the string).

创建一个新类，该类将保存您3列的数据:

Create a new class that will hold the data for your 3 columns:

class Drive
{
    public string Name { get; set; }
    public string Date { get; set; }
    public string Size { get; set; }
}

然后替换为:

foreach (string s in Directory.GetLogicalDrives())  
{  
    filelist.Items.Add(s);   
}

与此相关，它将生成数据项:

with this, which will generate the data items:

var drives = Directory.GetLogicalDrives().Select(d => new Drive { Name = d });

foreach (var drive in drives)
{
    MyListView.Items.Add(drive);
}

像这样设置您的 ListView ，以便每一列都从每个项目中自己的属性中获取数据:

Setup your ListView like this so that each column gets data from its own property in each item:

<ListView x:Name="MyListView">
    <ListView.View>
        <GridView>
            <GridView.Columns>
                <GridViewColumn Header="filename" DisplayMemberBinding="{Binding Name}"/>
                <GridViewColumn Header="date"  DisplayMemberBinding="{Binding Date}"/>
                <GridViewColumn Header="size"  DisplayMemberBinding="{Binding Size}"/>
            </GridView.Columns>
        </GridView>
    </ListView.View>
</ListView>
