Question

我在表单的各个选项卡中都有5个网格视图，我需要在单个Excel工作表或工作簿的不同选项卡中显示所有这些数据。

You can merge all datables in single dataset by putting following lines in code.

Dataset.Tables.Add(DataTable)

once your dataset is prepared then you can export it via EXCEL COM Component with following code.

public class WorkbookEngine
{
public static void CreateWorkbook(DataSet ds, String path)
{
XmlDataDocument xmlDataDoc = new XmlDataDocument(ds);
XslTransform xt = new XslTransform();
StreamReader reader =new StreamReader(typeof (WorkbookEngine).Assembly.GetManifestResourceStream(typeof (WorkbookEngine), “Excel.xsl”));
XmlTextReader xRdr = new XmlTextReader(reader);
xt.Load(xRdr, null, null);
StringWriter sw = new StringWriter();
xt.Transform(xmlDataDoc, null, sw, null);
StreamWriter myWriter = new StreamWriter (path + “\\Report.xls”);
myWriter.Write (sw.ToString());
myWriter.Close ();
}
}
