「Microsoft.ACE.OLEDB.12.0」提供程序未在本地機器錯誤消息中註冊

-1

我不明白我在哪裏錯了。「Microsoft.ACE.OLEDB.12.0」提供程序未在本地機器錯誤消息中註冊

當我使用本地機器程序成功運行。但是當我在服務器上上傳它會給喜歡的「Microsoft.ACE.OLEDB.12.0」供應商的錯誤未註冊在本地計算機上

  protected void btnImport_Click(object sender, EventArgs e) 
      { 
     // try{ 
      string connectionstring = ""; 
      string filename = Path.GetFileName(FileUpload1.PostedFile.FileName); 
     string fileextension = Path.GetExtension(FileUpload1.PostedFile.FileName); 
     string filelocation = Server.MapPath("~/file/") + filename; 
     FileUpload1.SaveAs(filelocation); 
     if (fileextension == ".xlsx") 
     { 
      connectionstring = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + filelocation + ";Extended Properties=\"Excel 12.0;HDR=YES;IMEX=2\""; 
      OleDbConnection conn = new OleDbConnection(connectionstring); 
      OleDbCommand cmd = new OleDbCommand(); 
      cmd.CommandType = System.Data.CommandType.Text; 
      cmd.CommandText = "select * from [Sheet1$]"; 
      cmd.Connection = conn; 
      OleDbDataAdapter oda = new OleDbDataAdapter(cmd); 
      System.Data.DataTable dt = new System.Data.DataTable(); 
      oda.Fill(dt); 
      grvExcelData.DataSource = dt; 
      Session["TaskTable"] = dt; 
      grvExcelData.DataBind(); 
     } 
     // }catch(Exception ex){Response.Write(ex.Message); } 
    }
