在WPF应用程序中将项目添加到C#中的ListView中
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 " "
?
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>
