c# - 单元格中的Excel图像

Question

如何将图像(图像类型)插入 Excel 工作表中的特定单元格

taperSheet = (Microsoft.Office.Interop.Excel.Worksheet)excelSheets.get_Item("Taper");

Microsoft.Office.Interop.Excel.Range cell = GetMyPictureCELL(taperSheet);

Image myImage = new Image();
RenderTargetBitmap bmp;

bmp = new RenderTargetBitmap((int)this.Width, (int)this.Height, 96, 96, PixelFormats.Pbgra32);
bmp.Render(myViewPort);

myImage.Source = bmp;
myImage.Stretch = Stretch.Uniform;

现在呢？我一直希望

cell.Add(myImage)

但我认为这并不那么容易。

下面的代码适合我

在我的例子中，我的图像源是一个视口(viewport) (myViewPort)图片的位置由cell决定

try
{
    Image myImage = new Image();
    RenderTargetBitmap bmp;
    PngBitmapEncoder encoder;
    string fileName;
    System.IO.Stream stream;
    object missing = System.Reflection.Missing.Value; 
    Microsoft.Office.Interop.Excel.Picture pic = null;
    Microsoft.Office.Interop.Excel.Pictures p = null;

    bmp = new RenderTargetBitmap((int)this.Width, (int)this.Height, 96, 96, PixelFormats.Pbgra32);
    bmp.Render(myViewPort);

    myImage.Source = bmp;
    myImage.Stretch = Stretch.Uniform;

    fileName = System.IO.Path.GetTempFileName();
    stream = System.IO.File.OpenWrite(fileName);

    encoder = new PngBitmapEncoder();
    encoder.Frames.Add(BitmapFrame.Create(bmp));
    encoder.Save(stream);
    stream.Close();

    p = taperSheet.Pictures(missing) as Microsoft.Office.Interop.Excel.Pictures; 
    pic = p.Insert(fileName, missing); 
    pic.Left = cell.Left;
    pic.Top = cell.Top;

}
catch { }

试试这个:

object missing = System.Reflection.Missing.Value;
Excel.Range picPosition = GetPicturePosition(); // retrieve the range for picture insert
Excel.Pictures p = yourWorksheet.Pictures(missing) as Excel.Pictures;
Excel.Picture pic = null;
pic = p.Insert(yourImageFilePath, missing);
pic.Left = Convert.ToDouble(picPosition .Left);
pic.Top = Convert.ToDouble(picPosition .Top);
pic.Placement = // Can be any of Excel.XlPlacement.XYZ value
