apose.cell中Excel问题
InsertPicturesIntoDataTabl和GetPicturesFromExcelFile这两个函数怎么定义// Excel文件转换为DataTable.
public static bool ExcelFileToDataTable(string filepath, out DataTable datatable, out string error)
{
error = "";
datatable = null;
try
{
if (File.Exists(filepath) == false)
{
error = "文件不存在";
datatable = null;
return false;
}
Aspose.Cells.Workbook workbook = new Aspose.Cells.Workbook();
workbook.Open(filepath);
Aspose.Cells.Worksheet worksheet = workbook.Worksheets[0];
datatable = worksheet.Cells.ExportDataTable(0, 0, worksheet.Cells.MaxRow + 1, worksheet.Cells.MaxColumn + 1);
//-------------图片处理-------------
Aspose.Cells.Pictures pictures = worksheet.Pictures;
if (pictures.Count > 0)
{
string error2 = "";
if (InsertPicturesIntoDataTable(pictures, datatable, out datatable, out error2) == false)
{
error = error + error2;
}
}
return true;
}
catch (System.Exception e)
{
error = e.Message;
return false;
}
}
public static bool ExcelFileToLists(string filepath, out IList[] lists, out string error)
{
error = "";
lists = null;
DataTable datatable = new DataTable();
IList list = new ArrayList();
Pictures[] pictures;
if (ExcelFileToDataTable(filepath, out datatable, out error) && GetPicturesFromExcelFile(filepath, out pictures, out error))
{
lists = new ArrayList[datatable.Rows.Count];
//------------DataTable转换成IList[]--------------
//数据
int nRow = 0;
foreach (DataRow row in datatable.Rows)
{
lists[nRow] = new ArrayList(datatable.Columns.Count);
for (int i = 0; i <= datatable.Columns.Count - 1; i++)
{
lists[nRow].Add(row[i]);
}
nRow++;
}
//图片
for (int i = 0; i < pictures.Length; i++)
{
foreach (Picture picture in pictures[i])
{
try
{
//----把图片转换成System.Drawing.Image----
//MemoryStream mstream = new MemoryStream();
//mstream.Write(picture.Data, 0, picture.Data.Length);
//System.Drawing.Image image = System.Drawing.Image.FromStream(mstream);
//----Image放入IList------
//图片有可能越界
if (picture.UpperLeftRow <= datatable.Rows.Count && picture.UpperLeftColumn <= datatable.Columns.Count)
{
lists[picture.UpperLeftRow][picture.UpperLeftColumn] = picture.Data;
}
}
catch (System.Exception e)
{
error = error + e.Message;
}
}
}
}
else
{
return false;
}
return true;
