目前我正在使用Excel.Interop.Shapes.AddPicture方法将图片添加到我的Excel文件中。
最初，所有工作都很好，首先编译程序并将其导出到excel中。但是第二次导出到excel等等，图片变得越来越小，随机变得越来越大，不符合我在Excel对象上设置的宽度和高度。
它应该是我导出到excel的所有内容，图像大小将是270 x 198.但是如果我重新编译程序并导出，第一次导出文件的图像一切都很好，但第二次尝试导出文件等等随着运行程序，图像大小将随机变得越来越大。
如果我的导出方法出错了，请告诉我。
以下是我用于导出到Excel的代码：

Excel.Sheets objSheets;
Excel._Worksheet objSheet = new Excel.Worksheet();
Excel.Range range;

saveDialog.Filter = "Excel files (*.xlsx)|*.xlsx|All files (*.*)|*.*";
saveDialog.FilterIndex = 2;
// Declare of Excel Instance
objApp = new Excel.Application();
objBooks = objApp.Workbooks;
objBook = objBooks.Add(Type.Missing);
objSheets = objBook.Worksheets;
List<String> photoList = new List<string>();
List<String> photoDescriptionList = new List<string>();
for (int i = 0; i < photoDataGridView.Rows.Count; i++)
{
if (photoDataGridView.Rows[i].Cells["Photo Path"].Value != null)
{
photoList.Add(photoDataGridView.Rows[i].Cells["Photo Path"].Value.ToString());
photoDescriptionList.Add(photoDataGridView.Rows[i].Cells["Photo Descriptions"].Value.ToString());
}
}
// Check file exist
bool isFileExist = false;
if (saveDialog.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
try
{

{
