I need to set image source dynamically, please note my image is in somewhere on the Network, here is my code
BitmapImage logo = new BitmapImage();
logo.BeginInit();
logo.UriSource = new Uri(@"pack://application:,,,\\myserver\\folder1\\Customer Data\\sample.png");
logo.EndInit(); // Getting the exception here
ImageViewer1.Source = logo;
Exception:
The URI prefix is not recognized
None of the above solutions worked for me. But this did:
myImage.Source = new BitmapImage(new Uri(@"/Images/foo.png", UriKind.Relative));
myImage.Source = new BitmapImage (new Uri (new Uri (Directory.GetCurrentDirectory(), UriKind.Absolute), new Uri (@"/Images/foo.png", UriKind.Relative)));
GetCurrentDirectory() return system32 directory. Instead You have to use this : loginLogo.Source = new BitmapImage(new Uri(new Uri(AppDomain.CurrentDomain.BaseDirectory, UriKind.Absolute), new Uri(@"Assets\Images\logo-adaptive-white.png", UriKind.Relative)));You just need one line:
ImageViewer1.Source = new BitmapImage(new Uri(@"\myserver\folder1\Customer Data\sample.png"));
The pack syntax you are using here is for an image that is contained as a Resource within your application, not for a loose file in the file system.
You simply want to pass the actual path to the UriSource:
logo.UriSource = new Uri(@"\\myserver\folder1\Customer Data\sample.png");
None of the methods worked for me as i needed to pull the image from a folder instead of adding it to the application. The below code worked:
TestImage.Source = GetImage("/Content/Images/test.png")
private static BitmapImage GetImage(string imageUri)
{
var bitmapImage = new BitmapImage();
bitmapImage.BeginInit();
bitmapImage.UriSource = new Uri("pack://siteoforigin:,,,/" + imageUri, UriKind.RelativeOrAbsolute);
bitmapImage.EndInit();
return bitmapImage;
}
My NET 7 project file looks as follows.
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<OutputType>WinExe</OutputType>
<TargetFramework>net7.0-windows</TargetFramework>
<Nullable>enable</Nullable>
<UseWPF>true</UseWPF>
</PropertyGroup>
<ItemGroup>
<None Remove="images\RuntimePicture.png" />
</ItemGroup>
<ItemGroup>
<Resource Include="images\RuntimePicture.png">
<CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
</Resource>
</ItemGroup>
</Project>
As the proj file indicates, I have an image in a folder called images. The code behind ctor looks as follows.
public MainWindow()
{
InitializeComponent();
ImageEx.Source = new BitmapImage(new Uri(@"/images/RuntimePicture.png", UriKind.Relative));
}
The main window xaml for image would be as follows.
<Image x:Name="ImageEx" Height="300" Width="500" />
Finally right click the png file and in the file properties window, ensure Build Action is set to Resource.
You are all wrong! Why? Because all you need is this code to work:
(image View) / C# Img is : your Image box
Keep this as is, without change ("ms-appx:///) this is code not your app name Images is your folder in your project you can change it. dog.png is your file in your folder, as well as i do my folder 'Images' and file 'dog.png' So the uri is :"ms-appx:///Images/dog.png" and my code :
private void Button_Click(object sender, RoutedEventArgs e)
{
img.Source = new BitmapImage(new Uri("ms-appx:///Images/dog.png"));
}
