ASP.net连接Excel的代码
首先添加命名空间 复制代码 代码如下: 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; } } asp.net 读取并显示excel数据的实现代码在Asp.net用C#建立动态Excelasp.net 操作excel的实现代码
