如何在文本框中插入多个字符？ [英] How to insert multiple characters in a textbox?

问题描述

我有这个XAML代码...

I have this XAML code...

<Grid>
        <TextBox Height="23" HorizontalAlignment="Left" Margin="74,78,0,0" x:Name="textBox1" VerticalAlignment="Top" Width="120" />
        <Button x:Name="button1" Content="A" Height="23" HorizontalAlignment="Left" Margin="12,156,0,0"  VerticalAlignment="Top" Width="75"  Click="button1_Click"></Button>
        <Button x:Name="button2" Content="B" Height="23" HorizontalAlignment="Left" Margin="93,156,0,0"  VerticalAlignment="Top" Width="75" Click="button1_Click"></Button>
        <Button x:Name="button3" Content="C" Height="23" HorizontalAlignment="Left" Margin="174,156,0,0" VerticalAlignment="Top" Width="75" Click="button1_Click" />
        <Button x:Name="button4" Content="D" Height="23" HorizontalAlignment="Left" Margin="12,200,0,0"  VerticalAlignment="Top" Width="75" Click="button1_Click" />
        <Button x:Name="button5" Content="E" Height="23" HorizontalAlignment="Left" Margin="185,228,0,0" VerticalAlignment="Top" Width="75"  Click="button1_Click" />
    </Grid>

这个XAML.CS代码.....

And this XAML.CS code.....

private void button1_Click(object sender, RoutedEventArgs e)
        {
            Button button = sender as Button;
            button.Content.ToString();

            textBox1.Text = button.Content.ToString();

         }

现在，当我按下按钮时，只显示一个字符。仍然使用我当前的XAML.CS代码，如何继续从这里按下按钮多次按下多个字符？

Now, when I press the button, only one character is being displayed. Still using my current XAML.CS code, how do continue from here in order to get multiple characters when the buttons are pressed multiple times??

推荐答案

你在做什么正在使用

textBox1.Text = button.Content.ToString();<br />

尝试像 textBox1.Text = textBox1.Text + Convert.ToString（button.Content）;
