来自String的ImageSource无法正常工作? [英] ImageSource from String not working?

问题描述

我的项目文件夹中有一堆* .tif图像.我也已将其添加到Visual Studio项目的"Templates \ Team Logos"文件夹中

I have a bunch of *.tif images in a folder in my project..which i've also added to my visual studio project in a folder located "Templates\Team Logos"

现在我是否将图像源设置为:

now if i set an image source to say:

<Image Name="UL_Team1_Image" Grid.Row="1" Grid.Column="1" Margin="5" Source="Team Logos\ARI.tif"></Image>

那行得通.但是现在，如果我尝试:

That works. But now if i try:

UL_ImageArr[a].Source = (ImageSource)new ImageSourceConverter().ConvertFromString("Team Logos\\ARI.tif");

那是行不通的.是什么赋予了?我收到了NullReferenceException ...但是对我来说没有意义?

that doesn't work. What gives? I get a NullReferenceException... but it doesn't make sense to me?

推荐答案

您可以在代码隐藏中使用它，我认为它比使用ImageSourceConverter更快.

You can use this in your code-behind, I think, it is more faster than using ImageSourceConverter.

BitmapImage bimage = new BitmapImage();
bimage.BeginInit();
bimage.UriSource = new Uri("Team Logos\\ARI.tif", UriKind.Relative);
bimage.EndInit();
UL_ImageArr[a].Source = bimage;

如果要使用ImageSourceConverter，则必须通过pack-uri引用图像文件:

If you want to use ImageSourceConverter you must refer to image file by pack-uri:

var converter = new ImageSourceConverter();
UL_ImageArr[a].Source = 
    (ImageSource)converter.ConvertFromString("pack://application:,,,/Team Logos/ARI.tif");
