ASP.NET（C#），怎么实现将excel数据导入SQL2005数据库中？

简单！库上右键  ==> 任务==>导入数据  出来向导    在数据源里选择EXCEL   下面可以选择EXECEL版本 EXCEL的路径

哦哦哦 是用代码啊 ！   用 NPOI 吧  此组件为数据库表和外部EXCEL的中间物！ 

此例为将EXCEL转为为DataTable 

你可以在写入TABLE的时候把数据写入数据库

有些过一个现成的东西，就是你说的这个需求，全给你贴出来，你自己看吧，哪里有疑问，在问我
public void BindData(DataSet Ds) {
try
{
tempTable = CreatTable(tempTable);
currPage = AspNetPager1.CurrentPageIndex;
this.AspNetPager1.RecordCount = Ds.Tables[0].Rows.Count;
AspNetPager1.CustomInfoHTML = "TOTAL：" + AspNetPager1.RecordCount.ToString() + " RECODES，DESPLAY: ";
AspNetPager1.CustomInfoHTML += "" + ((currPage - 1) * AspNetPager1.PageSize + 1) + "" + "-";
if (AspNetPager1.RecordCount < currPage * AspNetPager1.PageSize)
{
AspNetPager1.CustomInfoHTML += (AspNetPager1.RecordCount).ToString() + "";
}
else
{
AspNetPager1.CustomInfoHTML += (currPage * AspNetPager1.PageSize).ToString() + "";
}

if (Ds != null && Ds.Tables[0].Rows.Count > 0) {
models.Visible = true;

for (int i = (currPage - 1) * AspNetPager1.PageSize; i < currPage * AspNetPager1.PageSize; i++) {
if (i <= Ds.Tables[0].Rows.Count - 1)
{
DataRow dr = tempTable.NewRow();
dr["BOLNo"] = Ds.Tables[0].Rows[i][0].ToString().ToUpper();
dr["RMANo"] = Ds.Tables[0].Rows[i][1].ToString().ToUpper();
dr["RMAIssualDate"] = Ds.Tables[0].Rows[i][2].ToString().ToUpper();
dr["CustomerName"] = Ds.Tables[0].Rows[i][3].ToString().ToUpper();
dr["Models"] = Ds.Tables[0].Rows[i][5].ToString().ToUpper();
dr["QTYRequest"] = Ds.Tables[0].Rows[i][6].ToString().ToUpper();
tempTable.Rows.Add(dr);
}
}
}
else
{
DataRow dr = tempTable.NewRow();
dr["BOLNo"] = 0;
tempTable.Rows.Add(dr);
}
GridData.DataSource = tempTable;
GridData.DataBind();
}

lbl_Msg.Text = "Please Check Excel Content,Error Message: " + ex.Message;

提示一下：1.使用OLEDB方式读取EXCEL文件，并验证文件信息；
2.将1中获得的数据，插入sql数据库中；

我这里有个通用的把excel数据导入数据库的方法不知道合不合适

建议你使用PageOffice，很简单的就能帮你解决这个问题啊，网上搜有很多他的示例代码，你搜搜看，参考一下啊。
