asp.net讀取excel中的數(shù)據(jù)并綁定在gridview

    這篇文章主要介紹了asp.net讀取excel中的數(shù)據(jù)并綁定在gridview上的方法,需要的朋友可以參考下
    前臺label，DropDownList，gridview控件
    aspx.cs核心代碼：
    代碼如下:
    using System.Data.OleDb;//需要引入命名
    public void Excel_Click(object sender, EventArgs e)
    {
    if (this.AttachmentFile.Value == "" && this.Label1.Text == "" && DropDownList2.SelectedValue == "")
    {
    Response.Write("<script>window.alert('請選擇要導入的文件')</script>");
    }
    if (this.AttachmentFile.Value != "" && this.DropDownList2.SelectedValue == "")
    {
    HttpFileCollection files = HttpContext.Current.Request.Files;
    HttpPostedFile postedFile = files[0];
    fileName = System.IO.Path.GetFileName(postedFile.FileName);
    if (fileName != "")
    {
    postedFile.SaveAs("\\localhost\文件夾\" + fileName);
    }
    string strConn;
    strConn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + "\\localhost\文件夾\" + fileName + ";Extended Properties=Excel 8.0;";//this.AttachmentFile.Value.ToString()
    OleDbConnection conn = new OleDbConnection(strConn);
    conn.Open();
    DataTable sheetNames = conn.GetOleDbSchemaTable(System.Data.OleDb.OleDbSchemaGuid.Tables, new object[] { null, null, null, "TABLE" });
    foreach (DataRow dr in sheetNames.Rows)
    {
    DropDownList2.Items.Add(dr[2].ToString());
    }
    this.Label1.Text = "\\localhost\文件夾\" + fileName;//this.AttachmentFile.Value.ToString();
    conn.Close();
    }
    if (this.Label1.Text.ToString() != "" && this.DropDownList2.SelectedValue != "")// && this.DropDownList1.SelectedValue.ToString() != "全部"
    {
    //綁定到gridview
    GridView1.DataSource = createDataSource(DropDownList2.SelectedValue.ToString(), this.Label1.Text.ToString());//, this.DropDownList1.SelectedValue.ToString()
    GridView1.DataBind();
    }
    }
    //以Excel為數(shù)據(jù)源獲取數(shù)據(jù)集
    private DataSet createDataSource(string select, string lable)
    {
    string strCon = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + lable + ";Extended Properties=Excel 8.0;";
    string strsql = "select 登記號碼,姓名,日期,簽到時間,簽退時間,部門 from [" + select + "] order by 部門,日期,姓名";//excel表格的字段
    OleDbConnection conn = new OleDbConnection(strCon);
    OleDbDataAdapter da = new OleDbDataAdapter(strsql, conn);
    try
    {
    conn.Open();
    DataSet ds = new DataSet();
    da.Fill(ds);
    conn.Close();
    return ds;
    }
    catch (Exception e)
    {
    Response.Write("<script>window.alert('沒有數(shù)據(jù),或者" + e.Message + "')</script>");
    return null;
    }
    }
    以上是插入07以前版本excel
    如果07版本以后只需要做小小修改
    代碼如下:
    string strCon = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + lable + ";Extended Properties=Excel 12.0;";
