ASP.net连接Excel
首先添加命名空间
using System.Data.OleDb;
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
strfile = Request.QueryString["filename"];//从其他页面传过来的文件路径
Excel(strfile);
}
}
private void Excel(string filepath)
{
try
{
Dataset ds = new DataSet();
string ConnStr = "Provider=Microsoft.Jet.OleDb.4.0;data source=" + filepath +
";Extended Properties='Excel 8.0; HDR=YES; IMEX=1'";//连接Excel的字符串
string query = "SELECT * from [student$]";//Excel中的表名称
OleDbCommand oleCommand = new OleDbCommand(query, new OleDbConnection(ConnStr));
OleDbDataAdapter oleAdapter = new OleDbDataAdapter(oleCommand);
oleAdapter.Fill(ds, "[student$]");
rowcount = ds.Tables[0].Rows.Count;
gridview1.DataSource = ds;
gridview1.DataBind();
lblmes.Text = "上传成功，数据如下所示，请确认：";//lblmes为label，显示提示信息
}
catch (OleDbException)
{
string filename = filepath.Substring(filepath.LastIndexOf('/') + 1);
lblmes.Text = "错误！请确认上传文件是否正确！当前上传的文件为：" + filename;
lbtnSure.Visible = false;
}
catch(Exception ee)
{
lblmes.Text = ee.Message;
}
}
