推荐答案

如果你的 getUsers 方法返回一个列表，数组或相似的，你可以简单地设置的的ItemsSource在ListView到用户列表。例如：

If your getUsers method returns a list, array, or similar, you could simply set the ItemsSource of the ListView to userList. For example:

ServiceReference1.ImojWCFServiceClient client = new ServiceReference1.ImojWCFServiceClient();
listView1.Items.Clear();
var userList = client.getUsers();
listView1.ItemsSource = userList;

如果不工作，转换到用户列表一个ObservableCollection设置的ItemsSource之前

If that doesn't work, convert userList to an ObservableCollection before setting the ItemsSource

您的XAML可能看起来像这样...

Your Xaml might look like this...

<ListView>
    <ListView.View>
        <GridView>
            <GridViewColumn Header="ID" DisplayMemberBinding="{Binding UserID}"/>
            <GridViewColumn Header="Name" DisplayMemberBinding="{Binding Name}"/>
            <GridViewColumn Header="Last Name" DisplayMemberBinding="{Binding LastName}"/>
        </GridView>
    </ListView.View>
</ListView>
