Asp.net & Aspose.cells 导入

Workbook workBook = new Workbook(this.fuFile.FileContent);
Aspose.Cells.Worksheet sheet = workBook.Worksheets[0];
Cells cells = sheet.Cells;

//DataTable dt = cells.ExportDataTable(0, 0, cells.MaxRow + 1, cells.MaxDataColumn + 1, true);
DataTable dt = new DataTable();
DataColumn newcolumn = null;
for (int i = 0; i < cells.MaxColumn + 1; i++)
{
newcolumn = new DataColumn(cells[0, i].StringValue);
dt.Columns.Add(newcolumn);
}

DataRow newRow = null;
for (int j = 0; j < cells.MaxRow; j++)
{
newRow = dt.NewRow();
for (int k = 0; k < cells.MaxColumn + 1; k++)
{
newRow[k] = cells[j + 1, k].StringValue;
}
dt.Rows.Add(newRow);
}

DataView dv = new DataView(dt);

string[] filterColumns = { name, ibn, auth, pub, time, path };

dt = dv.ToTable(true, filterColumns);

以上代码中，首先要引用Aspose.cells 命名空间，至于Aspose.cells动态库，网上皆可下载

fuFile指asp.net页面中的上传控件。被注释掉的第5行就相当于6-23行，为了将从excel文件中读到的内容转化为DataTable表。
25行将datatable 转化为dataview，这样是为了下面的，按照指定的列对所有数据去掉重复记录，最后一句代码在去重的同时，把dataview又转化为了datatable
