如何在windows phone code behind（c#）中为图像提供imagesource

动态绑定图像时，这不起作用

Image Imgsource = new Image();

Imgsource.Source = new BitmapImage(new Uri("/Finder;component/Images/Chrysanthemum.png", UriKind.RelativeOrAbsolute));

提前感谢

您的代码创建了一个

图像

元素。但是，您需要将该元素添加到页面中的容器中。例如，

LayoutRoot

网格：

Image Imgsource = new Image();
Imgsource.Source = new BitmapImage(new Uri("/Finder;component/Images/Chrysanthemum.png", UriKind.RelativeOrAbsolute));
this.LayoutRoot.Children.Add(Imgsource);

您需要通过图像转换器进行绑定：

 public class ImageConverter : IValueConverter
 {
      public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
      {
           MemoryStream memStream = new MemoryStream((byte[])value,false);
           BitmapImage empImage = new BitmapImage();
           empImage.SetSource(memStream);
           return empImage; 
      }
      public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
      {
           throw new NotImplementedException();
      }
 }

请试试这个

  public void setimagebackgroud(string uri)
    {
        ImageBrush imageBrush = new ImageBrush();
        Image image = new Image();
        image.Source = new BitmapImage(new Uri(uri,UriKind.RelativeOrAbsolute));
        imageBrush.ImageSource = image.Source;
    }

“绑定动态”是什么意思，“不工作”是什么意思？不显示？是否有例外？@anderZubi-编辑了标题。。希望你现在明白了…你需要通过图像转换器进行绑定

  public void setimagebackgroud(string uri)
    {
        ImageBrush imageBrush = new ImageBrush();
        Image image = new Image();
        image.Source = new BitmapImage(new Uri(uri,UriKind.RelativeOrAbsolute));
        imageBrush.ImageSource = image.Source;
    }
