Question

我几乎写了一段代码，根据随机的int值选择要在imagebox中加载哪些图像。我将所有图像存储在名为＆＃34; projectImages＆＃34;在我的解决方案资源管理器我得到的错误是＆＃34;未处理的类型＆＃39; System.UriFormatException＆＃39;发生在System.dll＆＃34; ＆＃34;附加信息：无效的URI＆＃34;。这可能意味着我没有正确连接链接。

提前致谢。

    {
       int[] ImageValues = new int[15];
       ImageValues[0] = 1;
       ImageValues[1] = 2;
       ImageValues[2] = 3;
       ImageValues[3] = 4;
       ImageValues[4] = 5;
       ImageValues[5] = 6;
       ImageValues[6] = 7;
       ImageValues[7] = 8;
       ImageValues[8] = 9;
       ImageValues[9] = 10;
       ImageValues[10] = 11;
       ImageValues[11] = 12;
       ImageValues[12] = 13;
       ImageValues[13] = 14;
       ImageValues[14] = 15;

       Random randomize = new Random();
       int initialValue = randomize.Next(1, 16);
       int finalValue = ImageValues[initialValue];

       if(finalValue == 1)
       {
           leftImagebox.Source = new BitmapImage(new Uri(@"projectImages\triangle.png"));

           rightImagebox.Source = new BitmapImage(new Uri(@"projectImages\square.png"));
           question.Content = "Kan jij de driehoek aanwijzen?";
       }

       else if(finalValue == 2)

       }

您是否确定已经在项目中引用了图像资源且路径正确，如果是，请尝试 new Uri(@"YourPath", UriKind.RelativeOrAbsolute)。

如果您使用WPF或Silverlight，我强烈建议您在项目中使用Pack Uri，here是关于pack uri的官方文档。

然后Uri应该是这样的：

new Uri(@"ms-appx:///,,,:YourPath/projectImages/triangle.png")

C＃用uri改变图像框的来源
