                        ListViewItem item;
                        if (displayName != null)
                        {
                            if (size != null)
                                item = new ListViewItem(new string[] {displayName.ToString(), size.ToString()});

                            else
                                item = new ListViewItem(new string[] { displayName.ToString() });
                                lvlUser.Items.Add(item);
                        }
                    }
                    catch (Exception ex)
                    { }
                }
            }

        }  
    }
}

xaml:

<Grid>
        <Button Content="Get All Programs" Margin="0 5" HorizontalAlignment="Left" VerticalAlignment="Top" Width="111" Click="Button_Click_1"/>
        <ListView Name="lvlUser" Margin="0 30 0 0">

                    <GridViewColumn Header="EstimatedTime"/>
                    <GridViewColumn Header="DisplayVersion"/>
                    <GridViewColumn Header="InstallDate"/>
                    <GridViewColumn Header="Publisher"/>                    
                    <GridViewColumn Header="InstalledOn"/>
                </GridView>
            </ListView.View>
        </ListView>

    </Grid>

像这样尝试 -

 item = new ListViewItem();
 item.Content = new string[] {displayName.ToString(), size.ToString()};

 lvlUser.Items.Add(item);
