我试图重新创建一个非常简单的 C# 项目示例我 WPF，它是一个简单的图像查看器 .. 从山姆的自学 C#，我设法打开打开的文件对话框，但是我如何将图像路径设置为WPF 中的 image.source 控制？
private void SearchBtn_Click(object sender, RoutedEventArgs e)
{
Microsoft.Win32.OpenFileDialog openfile = new Microsoft.Win32.OpenFileDialog();
openfile.DefaultExt = "*.jpg";
openfile.Filter = "Image Files|*.jpg";
Nullable<bool> result = openfile.ShowDialog();
if (result == true)
{
//imagebox.Source = openfile.FileName;
}
}
采纳答案by Charlie
imagebox.Source = new BitmapImage(new Uri(openfile.FileName));

you'll need to change the File Name into a URI and then create a bitmapimage
您需要将文件名更改为 URI，然后创建位图图像
:
：
if (File.Exists(openfile.FileName))
{
// Create image element to set as icon on the menu element
BitmapImage bmImage = new BitmapImage();
bmImage.BeginInit();
bmImage.UriSource = new Uri(openfile.FileName, UriKind.Absolute);
bmImage.EndInit();
// imagebox.Source = bmImage;
}

You can also add the image as a resource, ie Add Existing item and change the image's Build Action property to Resource
您还可以将图像添加为资源，即添加现有项目并将图像的构建操作属性更改为资源
then reference it this way
然后以这种方式引用它
BitmapImage bitImg = new BitmapImage();
bitImg.BeginInit();
bitImg.UriSource = new Uri("./Resource/Images/Bar1.png", UriKind.Relative);
bitImg.EndInit();
((Image)sender).Source = bitImg;
This way you dont need to include the image with the program, its bundled into the package as a resource
这样你就不需要在程序中包含图像，它作为资源捆绑到包中
