C#中如何读取excel中的图片并保存到数据库中
现需要实现一个功能:读取excel中的图片并将它保存到数据库中(web页面中),从网上看了几种方法,但试了总是不成功,一种方法的代码如下,求解。。有更好的方法么?谢谢
private int StartRow = 2; //读的起始行
private int ImgCount = 0;
protected void btnImport_Click(object sender, EventArgs e)
{
try
{
string path = "C:\\Users\\wang\\Desktop\\user.xlsx";
Microsoft.Office.Interop.Excel.Application excel = new Microsoft.Office.Interop.Excel.Application();//引用Excel对象
Microsoft.Office.Interop.Excel.Workbook workbook = excel.Workbooks.Add(path);
excel.UserControl = true;
System.Text.StringBuilder sb = new System.Text.StringBuilder();
excel.Visible = false;
for (int i = 0; i < workbook.Worksheets.Count; i++)//循环取所有的Sheet.
{
Microsoft.Office.Interop.Excel.Worksheet sheet = workbook.Worksheets.get_Item(i + 1) as Microsoft.Office.Interop.Excel.Worksheet;//从1开始.
for (int row = StartRow; row <= sheet.UsedRange.Rows.Count; row++)
{
string imgName = string.Empty;
//取单元格值;
for (int col = 1; col <= sheet.UsedRange.Columns.Count; col++)
{
Microsoft.Office.Interop.Excel.Range range = sheet.Cells[row, col] as Microsoft.Office.Interop.Excel.Range;
sb.Append("," + col.ToString() + ":" + range.Text);
if(col==1)
imgName = range.Text.ToString();//得到第一列的名称,作为图片名称
}
sb.Append(System.Environment.NewLine);
//取存图片;
if (sheet.Shapes.Count > row - StartRow)
{
Microsoft.Office.Interop.Excel.Shape s = sheet.Shapes.Item(row - StartRow + 1) as Microsoft.Office.Interop.Excel.Shape;
s.CopyPicture(Appearance.Button, Microsoft.Office.Interop.Excel.XlCopyPictureFormat.xlBitmap); //COPY到内存。
IDataObject iData = Clipboard.GetDataObject(); //这里为什么总是为null?
if (iData.GetDataPresent(DataFormats.Bitmap))
{
ImgCount += 1; //保存的图片数加1
}
else
{
}
}
}
}
}
catch (Exception)
{
throw;
}
}
