如果您的 getUsers 方法返回列表，数组或类似方法，则可以将ListView的ItemsSource设置为 userList 。例如：

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

如果不起作用，在设置ItemsSource

$之前将userList转换为ObservableCollection b
$ b

您的Xaml可能看起来像这样...

 < ListView> 
< ListView.View> 
< GridView> 
< GridViewColumn Header =IDDisplayMemberBinding ={Binding UserID}/> 
< GridViewColumn Header =NameDisplayMemberBinding ={Binding Name}/> 
< GridViewColumn Header =Last NameDisplayMemberBinding ={Binding LastName}/> 
< / GridView> 
< /ListView.View> 
< / ListView> 
 

I'm trying to display data from my Entitity Framework database to my ListView in my WPF C# application.

I'm using WCF app as my host, where I keep my methods for displaying data, adding data, etc., and I have WPF app as my client, where I use the code to display data from database to my ListView.

This is my code

ServiceReference1.ImojWCFServiceClient client = new ServiceReference1.ImojWCFServiceClient();
listView1.Items.Clear();
var userList = client.getUsers();
foreach (var user in userList)
{
   ListViewItem listOfUsers;
   string[] list = new string[3];
   list[0] = user.UserID.ToString();
   list[1] = user.Name;
   list[2] = user.LastName;
   listOfUsers = new ListViewItem(list);
   listView1.Items.Add(listOfUsers);
}

This is the error that I get

Can somebody help me fix this code?

Any help is appreciated!

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;

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

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>
