太狠了，就这样，相信很多朋友都会碰到这个问题，

只是有一点，如果表的字段类型为int的话，就要把下面的这个去掉，不然excel打不开

//对于数字，采用Number数字类型
//if (c > 1)
//{
// Response.Write("<Cell ss:StyleID='border'><Data ss:Type='Number'>" + dt.Rows[j][c].ToString() + "</Data></Cell>");
//}
//else
//{
Response.Write("<Cell ss:StyleID='border'><Data ss:Type='String'>" + dt.Rows[j][c].ToString() + "</Data></Cell>");
//}

使用NPOI比较简单些，先创建文档，再创建sheet，再创建行。再创建列。从网上下载个。。。挺好用的也很容易理解

你看没看代码啊？
里面的思路你了解吗？

你循环
for(int i=0;i<DataSet.Tables.Count;i++)
不就可以了吗

循环DataSet，更简单
