WPF setting a MenuItem.Icon in code

问题:

I have an images folder with a png in it. I would like to set a MenuItem's icon to that png. How do I write this in procedural code?

回答1:

menutItem.Icon = new System.Windows.Controls.Image 
       { 
           Source = new BitmapImage(new Uri("images/sample.png", UriKind.Relative)) 
       };

回答2:

<MenuItem>
  <MenuItem.Icon>
    <Image>
      <Image.Source>
        <BitmapImage UriSource="/your_assembly;component/your_path_here/Image.png" />
      </Image.Source>
    </Image>
  </MenuItem.Icon>
</MenuItem>

Just make sure your image in also included in the project file and marked as resource, and you are good to go :)

Arcturus's answer is good because it means you have the image file in your project rather than an independent folder.

So, in code that becomes...

menutItem.Icon = new Image
        {
        Source = new BitmapImage(new Uri("pack://application:,,,/your_assembly;component/yourpath/Image.png"))
        }

This is how I used it (this way it dont need to be built into the assembly):

MenuItem item = new MenuItem();
string imagePath = "D:\\Images\\Icon.png");
Image icon = new Image();
icon.Source= new BitmapImage(new Uri(imagePath, UriKind.Absolute));
item.Icon = icon;

This is a bit shorter :D

<MenuItem Header="Example">
   <MenuItem.Icon>
      <Image Source="pack://siteoforigin:,,,/Resources/Example.png"/>
   </MenuItem.Icon>
</MenuItem>

回答6:

For those of you using vb.net, to do this you need to use this: menuItem.Icon = New Image() With {.Source = New BitmapImage(New Uri("pack://application:,,,/your_assembly;component/yourpath/Image.png"))}

This is what worked for me

<MenuItem Header="delete   ctrl-d" Click="cmiDelete_Click">
    <MenuItem.Icon>
        <Image>
            <Image.Source>
                <ImageSource>Resources/Images/delete.png</ImageSource>
            </Image.Source>
        </Image>
    </MenuItem.Icon>
</MenuItem>

You can also use your Visual Studio to insert a icon. This is the easiest way

• Right click at you project in the solution explorer
• chose Properties
• Make sure you're in the application page.
• @ recources you see: Icon and Manifest
• @ Icon: Click browse and pick your icon.

Problem solved.
