【问题描述】:
我正在尝试为 Windows Mobile PDA 开发应用程序,但我在从资源文件夹获取 .png 图像时遇到问题。
我在项目 Resources 文件夹中有许多图像,我想做的只是以编程方式(即仅使用代码)使用项目 Resources 文件夹中的背景图像绘制一个图像框。
例如:
PictureBox pictureBoxBlueCounter = new PictureBox();
//pictureBoxBlueCounter = new System.Windows.Forms.PictureBox();
pictureBoxBlueCounter.Image = global::StrikeOutMobile.Properties.Resources.counter_square_blue;
pictureBoxBlueCounter.Location = new System.Drawing.Point(30, 30);
pictureBoxBlueCounter.Name = "pictureBoxblueCounter";
pictureBoxBlueCounter.Size = new System.Drawing.Size(240, 210);
pictureBoxBlueCounter.SizeMode = System.Windows.Forms.PictureBoxSizeMode.StretchImage;
Controls.Add(pictureBoxBlueCounter);
就目前而言,上面的代码给了我一个“TargetInvocationException was unhandled”错误,我不知道如何解决它!
我该如何解决这个问题?
这是完整的 TargetInvocationException 信息:
System.Reflection.TargetInvocationException was unhandled

【问题讨论】:
-
你能发布完整的
exception.ToString()吗? TargetInvocationException 的内部异常很可能表明真正的问题...... -
感谢您抽出宝贵时间查看我的问题 nick!我现在已经添加了完整的异常信息!
-
你是在 UI 线程上做这个吗?
