我的 MainUI 中有一个列表框。我通过以下代码将 Item 添加到它：

for (int i = 0; i < 50; i++) {
    ListBoxItem sub1 = new ListBoxItem();
    if (i % 2 == 0) {
       sub1.Foreground = Brushes.Red;
    } else {
       sub1.Foreground = Brushes.Green;
    }

    sub1.Content = i;
    this.listStatus.Items.Add(sub1);
}

之后，我想将该值保存到红色和绿色的文件中。我尝试将它们写入 .doc 文件购买我只能通过以下代码获取黑色字符：

int lisboxcounter = 0;

FileStream fs = new FileStream(@"D:\Test.doc", FileMode.OpenOrCreate);

StreamWriter s = new StreamWriter(fs);
while (this.listStatus.Items.Count > lisboxcounter) {
   s.WriteLine(this.listStatus.Items[lisboxcounter].ToString());
   lisboxcounter++;
}

s.Close();
fs.Close();

和值为System.Windows.Controls.ListBoxItem:0。

我怎样才能写出只有价值的东西；0,1,2,3 ...红色和绿色？

多谢。

最好的办法是写入 RichTextBox，然后将内容保存到 RTF 文件。

XAML

    <StackPanel Orientation="Horizontal"
                Grid.Row="0">
        <Button Width="80"
                Content="Load"
                Name="_loadButton"
                Click="_loadButton_Click" />
        <Button Width="80"
                Content="Save"
                Name="_saveButton"
                Click="_saveButton_Click" />
    </StackPanel>

    <RichTextBox Grid.Row="1" Name="_rtfBox" VerticalScrollBarVisibility="Auto" />
</Grid>
