Epicor10-Image.Save 方法

Question

我正在尝试在 Epicor 10 中构建自定义 window。我添加了一个图片框，然后尝试从文件中打开图片 (bmp)，然后使用另一个按钮将其保存到其他地方。问题是在 Epicor 10 的自定义工具对话框中，我在编译时编写代码时不断收到此错误：

Error: CS1061 - line 258 (953) - 'object' does not contain a definition for 'Save' and no extension method 'Save' accepting a first argument of type 'object' could be found (are you missing a using directive or an assembly reference?)
 ** Compile Failed. **

现在，当我复制代码并使用 Visual Studio 2012 重新创建一个 windows 表单应用程序时，一切正常，编译完全没有错误。

代码很简单：

private void epiButtonC6_Click(object sender, System.EventArgs args)
{
    var fd = new SaveFileDialog();
        fd.Filter = "Bmp(*.Bmp)|*.bmp;| Jpg(*Jpg)|*.jpg;| Png(*Png)|*.png";
        fd.AddExtension = true;

        if (fd.ShowDialog() == System.Windows.Forms.DialogResult.OK)
        {
            switch (Path.GetExtension(fd.FileName).ToUpper())
            {
                case ".BMP":                        
                    epiPictureBoxC1.Image.Save(fd.FileName, System.Drawing.Imaging.ImageFormat.Bmp);
                    break;
                case ".JPG":
                    epiPictureBoxC1.Image.Save(fd.FileName, System.Drawing.Imaging.ImageFormat.Jpeg);
                    break;
                case ".PNG":
                    epiPictureBoxC1.Image.Save(fd.FileName, System.Drawing.Imaging.ImageFormat.Png);
                    break;
                default:
                    break;
            }
        }       
}

EpiPictureBox 并非源自 System.Windows.Forms.PictureBox。它源自 Infragistics.Win.UltraWinEditors.UltraPictureBox。

System.Windows.Forms.PictureBox 上的图像属性的类型为 System.Drawing.Image，其中图像Infragistics.Win.UltraWinEditors.UltraPictureBox 的属性是 System.Object。这就是为什么事情不像您期望的那样表现。

我能够通过使用以下内容获得一个模型，只要您确定分配给 epiPictureBoxC1.Image 的属性的任何内容确实能够被转换为 System.Drawing.Image

switch (Path.GetExtension(fd.FileName).ToUpper())
        {
            case ".BMP":                        
                ((System.Drawing.Image)epiPictureBoxC1.Image).Save(fd.FileName, System.Drawing.Imaging.ImageFormat.Bmp);
                break;
            case ".JPG":
                ((System.Drawing.Image)epiPictureBoxC1.Image).Save(fd.FileName, System.Drawing.Imaging.ImageFormat.Jpeg);
                break;
            case ".PNG":
                ((System.Drawing.Image)epiPictureBoxC1.Image).Save(fd.FileName, System.Drawing.Imaging.ImageFormat.Png);
                break;
            default:
                break;
        }
