我正在使用C#构建一个WPF应用程序。我想弹出一个对话框来提示用户输入他/她的名字。之后,我将跟踪名称,并使用名称将一些数据保存到.txt文件中。
例如,:
名称输入是
姓名=“约翰”
所以我有数据
data="1,2,3";
然后将“数据”保存在John.txt文件中。
有人知道怎么做吗?
我认为问题是如何弹出一个对话框供用户输入名称.

我更喜欢使用不锁定应用程序的对话框,而不是更传统的Win32对话框。
示例

输入对话框隐藏

在本例中,我使用了一个简化的基于MVVM的解决方案,用于我的应用程序。它可能不是很漂亮,但应该给你一个坚实的想法的基础,它的背后。
XAML:
<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<Grid>
<StackPanel>
<Button Content="Cool Button" x:Name="CoolButton" Click="CoolButton_Click"/>
<ListBox x:Name="MyListBox"/>
</StackPanel>
<!-- It's important that this is in the end of the XAML as it needs to be on top of everything else! -->
<Grid x:Name="InputBox" Visibility="Collapsed">
<Grid Background="Black" Opacity="0.5"/>
<Border
MinWidth="250"
Background="Orange"
BorderBrush="Black"
BorderThickness="1"
CornerRadius="0,55,0,55"
HorizontalAlignment="Center"
VerticalAlignment="Center">
<StackPanel>
<TextBlock Margin="5" Text="Input Box:" FontWeight="Bold" FontFamily="Cambria" />
<TextBox MinWidth="150" HorizontalAlignment="Center" VerticalAlignment="Center" x:Name="InputTextBox"/>
<StackPanel Orientation="Horizontal" HorizontalAlignment="Center">
<Button x:Name="YesButton" Margin="5" Content="Yes" Background="{x:Null}" Click="YesButton_Click"/>
<Button x:Name="NoButton" Margin="5" Content="No" Background="{x:Null}" Click="NoButton_Click" />
</StackPanel>
</StackPanel>
</Border>
</Grid>
</Grid>
</Window>显示此对话框非常容易,因为您只需将InputBox网格的可见性设置为可见。然后,您只需处理Yes / No按钮,并从TextBox获取输入文本。
因此,不必使用需要ShowDialog()的代码,只需将Visibility选项设置为Visible即可。在这个示例中仍然有一些事情要做,我们将在代码隐藏中处理,例如,在处理Yes/No按钮单击后清除InputText框。
代码隐藏:
namespace WpfApplication1
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
private void CoolButton_Click(object sender, RoutedEventArgs e)
{
// CoolButton Clicked! Let's show our InputBox.
InputBox.Visibility = System.Windows.Visibility.Visible;
}
private void YesButton_Click(object sender, RoutedEventArgs e)
{
// YesButton Clicked! Let's hide our InputBox and handle the input text.
InputBox.Visibility = System.Windows.Visibility.Collapsed;
// Do something with the Input
String input = InputTextBox.Text;
MyListBox.Items.Add(input); // Add Input to our ListBox.
// Clear InputBox.
InputTextBox.Text = String.Empty;
}
private void NoButton_Click(object sender, RoutedEventArgs e)
{
// NoButton Clicked! Let's hide our InputBox.
InputBox.Visibility = System.Windows.Visibility.Collapsed;
// Clear InputBox.
InputTextBox.Text = String.Empty;
}
}
}在本例中,代码隐藏可以很容易地使用依赖项或作为ViewModel逻辑来完成,但为了简单起见,我将其保存在代码隐藏中。

这是我的解决办法。它是完全可定制的。
string inputRead = new InputBox("text").ShowDialog();或者,如果你愿意
string inputRead= new InputBox("Insert something", "Title", "Arial", 20).ShowDialog()这是这个类的代码
public class InputBox
{
Window Box = new Window();//window for the inputbox
FontFamily font = new FontFamily("Tahoma");//font for the whole inputbox
int FontSize=30;//fontsize for the input
StackPanel sp1=new StackPanel();// items container
string title = "InputBox";//title as heading
string boxcontent;//title
string defaulttext = "Write here your name...";//default textbox content
string errormessage = "Invalid answer";//error messagebox content
string errortitle="Error";//error messagebox heading title
string okbuttontext = "OK";//Ok button content
Brush BoxBackgroundColor = Brushes.GreenYellow;// Window Background
Brush InputBackgroundColor = Brushes.Ivory;// Textbox Background
bool clicked = false;
TextBox input = new TextBox();
Button ok = new Button();
bool inputreset = false;
public InputBox(string content)
{
try
{
boxcontent = content;
}
catch { boxcontent = "Error!"; }
windowdef();
}
public InputBox(string content,string Htitle, string DefaultText)
{
try
{
boxcontent = content;
}
catch { boxcontent = "Error!"; }
try
{
title = Htitle;
}
catch
{
title = "Error!";
}
try
{
defaulttext = DefaultText;
}
catch
{
DefaultText = "Error!";
}
windowdef();
}
public InputBox(string content, string Htitle,string Font,int Fontsize)
{
try
{
boxcontent = content;
}
catch { boxcontent = "Error!"; }
try
{
font = new FontFamily(Font);
}
catch { font = new FontFamily("Tahoma"); }
try
{
title = Htitle;
}
catch
{
title = "Error!";
}
if (Fontsize >= 1)
FontSize = Fontsize;
windowdef();
}
private void windowdef()// window building - check only for window size
{
Box.Height = 500;// Box Height
Box.Width = 300;// Box Width
Box.Background = BoxBackgroundColor;
Box.Title = title;
Box.Content = sp1;
Box.Closing += Box_Closing;
TextBlock content=new TextBlock();
content.TextWrapping = TextWrapping.Wrap;
content.Background = null;
content.HorizontalAlignment = HorizontalAlignment.Center;
content.Text = boxcontent;
content.FontFamily = font;
content.FontSize = FontSize;
sp1.Children.Add(content);
input.Background = InputBackgroundColor;
input.FontFamily = font;
input.FontSize = FontSize;
input.HorizontalAlignment = HorizontalAlignment.Center;
input.Text = defaulttext;
input.MinWidth = 200;
input.MouseEnter += input_MouseDown;
sp1.Children.Add(input);
ok.Width=70;
ok.Height=30;
ok.Click += ok_Click;
ok.Content = okbuttontext;
ok.HorizontalAlignment = HorizontalAlignment.Center;
sp1.Children.Add(ok);
}
void Box_Closing(object sender, System.ComponentModel.CancelEventArgs e)
{
if(!clicked)
e.Cancel = true;
}
private void input_MouseDown(object sender, MouseEventArgs e)
{
if ((sender as TextBox).Text == defaulttext && inputreset==false)
{
(sender as TextBox).Text = null;
inputreset = true;
}
}
void ok_Click(object sender, RoutedEventArgs e)
{
clicked = true;
if (input.Text == defaulttext||input.Text == "")
MessageBox.Show(errormessage,errortitle);
else
{
Box.Close();
}
clicked = false;
}
public string ShowDialog()
{
Box.ShowDialog();
return input.Text;
}
}希望它能有用。

只需在中创建另一个窗口类,它在公共属性中保存用户名。然后在主窗口的某个地方创建此窗口的一个实例,并使用ShowDialog方法显示它。这会阻塞,直到您的“对话框”窗口关闭。然后您可以从公共属性中获取用户名,并对它做任何您想做的事情。
