Question

我已经获得了代码，其中MainWindow中的字符串变量名为＆＃34; repeatNumber＆＃34; - MainWindow中还有两个按钮。 btn2应该打开一个新窗口＆＃39; otherwindow＆＃39;其中包含repeatNumber字符串并显示图片。

＆＃39;窗口1＆＃39;不包含＆＃39; getRepeatedNumber＆＃39;的定义没有扩展方法＆＃39; getRepeatedNumber＆＃39;接受类型＆＃39; Window1＆＃39;的第一个参数。可以找到。

任何人都可以帮我吗？这可以在不使用MVVM的情况下修复吗？代码如下：

Mainwindow.cs

    public partial class MainWindow : Window
    {
        private string repeatNumber;

        public MainWindow()
        {
            InitializeComponent();

            string[] assignments = new string[] { "https://cdn2.iconfinder.com/data/icons/animals/48/Turtle.png", "https://cdn2.iconfinder.com/data/icons/animals/48/Butterfly.png", "https://cdn2.iconfinder.com/data/icons/animals/48/Dolphin.png", "https://cdn2.iconfinder.com/data/icons/animals/48/Elephant.png", "https://cdn2.iconfinder.com/data/icons/animals/48/Hippopotamus.png", "https://cdn2.iconfinder.com/data/icons/animals/48/Panda.png" };
            Random rnd = new Random();

            string[] randomingArray = assignments.OrderBy(x => rnd.Next()).ToArray();


            List<Images> animals = new List<Images>();

            for (int i = 1; i < 100; i++)
            {
                if (i == 9)
                {
                    repeatNumber = randomingArray[i % randomingArray.Length];
                    animals.Add(new Images() { Source = repeatNumber, Number = i });
                }
                else if ((i % 9) == 0)
                {
                    animals.Add(new Images() { Source = repeatNumber, Number = i });
                }
                else
                {
                    animals.Add(new Images() { Source = randomingArray[i % rnd.Next(1, 5)], Number = i });
                }
                ItemsControl1.ItemsSource = animals;
            }
        }


        private void btn1_Click(object sender, RoutedEventArgs e)
        {
            MessageBox.Show("test");
        }
        private void btn2_Click(object sender, RoutedEventArgs e)
        {
            Window1 otherwindow = new Window1();
            otherwindow.Show();
            string value = otherwindow.getRepeatedNumber; <--- This line gives me the error
        }
    }

class Images
{
    public int Number { get; set; }
    public string Source { get; set; }
}

Mainwindow.xaml

<Grid>
        <ListBox x:Name="ItemsControl1">

            <ListBox.ItemsPanel>

                <ItemsPanelTemplate>

                    <UniformGrid Columns="5">
                    </UniformGrid>

                </ItemsPanelTemplate>
            </ListBox.ItemsPanel>
            <ListBox.ItemTemplate>
                <DataTemplate>
                    <Border BorderBrush="Black" BorderThickness="3" Width="Auto" Height="Auto">
                        <StackPanel Orientation="Horizontal">
                            <TextBlock Text="{Binding Number}"/>
                            <Image Source="{Binding Source}" Margin="0,0,5,0"/>
                        </StackPanel>
                    </Border>
                </DataTemplate>
            </ListBox.ItemTemplate>

        </ListBox>
        <Grid>
            <Button x:Name="btn1" Click="btn1_Click" Height="20" VerticalAlignment="Bottom" Margin="127,0,316,0" Content="Instruction"></Button>
            <Button x:Name="btn2" Click="btn2_Click" Height="20" VerticalAlignment="Bottom" Margin="300,0,109,0" Content="Results" Width="74"></Button>

        </Grid>
    </Grid>

Window1.cs

 public class Window2 : Window
{
    public string getRepeatedNumber { get; set; }

    public Window2(string repeatNumber)
    {
       getRepeatedNumber = repeatNumber;
    }
}

和Window1.xaml只是

<Grid>

</Grid>

Window1不包含定义
