在C＃中调整WrapPanel内的图像大小 [英] Resizing Images within a WrapPanel in C#

问题描述

我正在尝试使用图像动态填充WrapPanel，

包含WrapPanel的窗口可以调整大小，我想

使图像内的图像当他们有更多的空间时，wrappanel调整大小。







我的问题是我希望图像调整大小如果我向wrappanel添加更多。



例如：

如果只有一个图像，它应该占用所有空间，

但是如果我添加另一个，它们都应该调整大小，这样两者都只占用一半的空间。

如果我调整窗口大小并使其成为两个图像应该增长更大，但是如果我缩小窗口，它们也应该缩小。



对不起我可怕的英语 -

我希望我能解释我的问题。



我的代码：

I'm trying to fill a WrapPanel dynamically with Images,
The Window that contains the WrapPanel is resizable, and i would like to
make the images within the wrappanel resize when they got more space.



My problem is that i want the images to resize if i add more to the wrappanel.

For example:
If there is only ONE image, it should take all the space it can,
but if i add another, they should both be resized, so that both only take half the space.
Both images should grow if i resize the Window and make it bigger, but they should also shrink if i shrink the Window.

I'm sorry for my terrible english-
I hope i could explain my problem.

My Code:

string path = s;
                   BitmapImage bit = new BitmapImage();
                   Uri ur = new Uri(path);
                   bit.BeginInit();
                   bit.UriSource = ur;
                   bit.EndInit();

                   System.Windows.Controls.Image tempimage = new System.Windows.Controls.Image();
                   tempimage.Source = bit;


                  tempimage.Stretch = Stretch.Uniform;

                  //### THESE DID NOT WORK
                  // tempimage.Height = Double.NaN;
                  //tempimage.Width = Double.NaN;
                   //wrapPanel1.ItemHeight = Double.NaN;
                   //wrapPanel1.ItemWidth = Double.NaN;
                   //###


                   wrapPanel1.Children.Add(tempimage);

有人能帮助我吗？

Hi Feverbird，



只需使用UniformGrid，例如：



MainWindow.cs：

Hi Feverbird,

Just use UniformGrid instead, for example:

MainWindow.cs:

<Window x:Class="WpfApplication4.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">
    <DockPanel LastChildFill="True">
        <Border DockPanel.Dock="Top">
            <Button Width="100" Content="Add" Click="Button_Click" />
        </Border>
        <UniformGrid x:Name="panel"  />
    </DockPanel>
</Window>

代码背后：

Code Behind:

/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
    }

    private void Button_Click(object sender, RoutedEventArgs e)
    {
        var image = new BitmapImage(new Uri("Choice_toxicity_icon.png", UriKind.RelativeOrAbsolute));

        panel.Children.Add(new Image() { Source = image , Stretch = Stretch.Fill});
    } 
}

最好的问候，
