动态生成WPF应用程序中的图像控制

Question

我想在WPF应用程序中动态创建图像控件，并设置该控件的属性...像大小，位置，颜色，sizemode 我该怎么做？给我任何样本码。

Answer 1

这是一个简单的例子，我已经做了哪些加载在标志堆栈溢出。

public partial class MainWindow : Window 
{ 
    public MainWindow() 
    { 
     InitializeComponent(); 
     Loaded += new RoutedEventHandler(MainWindow_Loaded); 
    } 

    void MainWindow_Loaded(object sender, RoutedEventArgs e) 
    { 
     var webImage = new BitmapImage(new Uri("http://sstatic.net/so/img/logo.png")); 
     var imageControl = new Image(); 
     imageControl.Source = webImage; 
     ContentRoot.Children.Add(imageControl); 
    } 
} 

和XAML ...

<Window x:Class="WpfExamples.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 x:Name="ContentRoot"> 

    </Grid> 
</Window> 

干杯，

你想显示一个图像文件或流？或者你要创建一个图像控件，并将其添加到代码中的窗口？

从here，MSDN上

// Create Image Element 
Image myImage = new Image(); 
myImage.Width = 200; 

// Create source 
BitmapImage myBitmapImage = new BitmapImage(); 

// BitmapImage.UriSource must be in a BeginInit/EndInit block 
myBitmapImage.BeginInit(); 
myBitmapImage.UriSource = new Uri(@"C:\Documents and Settings\All Users\Documents\My Pictures\Sample Pictures\Water Lilies.jpg"); 

// To save significant application memory, set the DecodePixelWidth or 
// DecodePixelHeight of the BitmapImage value of the image source to the desired 
// height or width of the rendered image. If you don't do this, the application will 
// cache the image as though it were rendered as its normal size rather then just 
// the size that is displayed. 
// Note: In order to preserve aspect ratio, set DecodePixelWidth 
// or DecodePixelHeight but not both. 
myBitmapImage.DecodePixelWidth = 200; 
myBitmapImage.EndInit(); 
//set image source 
myImage.Source = myBitmapImage;
