c#dev操作读取excel方法

一:使用spreadsheetControl1 方法

1:打开excel;

  private void barButtonItem1_ItemClick(object sender, DevExpress.XtraBars.ItemClickEventArgs e)
        {
            //if (Convert.ToInt32(trv_menu.SelectedNode.Tag) == 0)
            //{
            //    MessageBox.Show("请先选择业务", "提示信息", MessageBoxButtons.OK);
            //    return;
            //}
            OpenFileDialog openFileDialog1 = new OpenFileDialog();
            openFileDialog1.Filter = "(*.xls)|*.xls|(*.xlsx)|*.xlsx|(*.csv)|*.csv";
            openFileDialog1.RestoreDirectory = true;
            if (openFileDialog1.ShowDialog() == DialogResult.OK)
            {
                spreadsheetControl1.LoadDocument(openFileDialog1.FileName);
            }
            spreadsheetControl1.ReadOnly = true;
        }

2:读取按行读取excel 处理每行中列的数值

 private void barButtonItem2_ItemClick(object sender, DevExpress.XtraBars.ItemClickEventArgs e)
        {

          //    status1.Visible = true;
            //读取Excele方法
            //当前数据行数
            int rowCount = spreadsheetControl1.ActiveWorksheet.Cells.CurrentRegion.RowCount;
            //当前数据列数
            int columnCount = spreadsheetControl1.ActiveWorksheet.Cells.CurrentRegion.ColumnCount;
            if (rowCount ==  && columnCount == )
            {
                MessageBox.Show("内容不能为空", "警告", MessageBoxButtons.OK, MessageBoxIcon.Warning);
                return;
            }
            for (int i = ; i < rowCount; i++)
            {
                string sr = spreadsheetControl1.ActiveWorksheet.Cells[i, ].Value.ToString();
                if (sr == "")
                {
                    //  blankcount++;
                    blankcountEvent(this, e);
               //     btnblank.Text = blankcount.ToString(); ;
                    continue;
                }
                //for (int j = 0; j < columnCount; j++)
                //{
                string zyzsId = spreadsheetControl1.ActiveWorksheet.Cells[i, ].Value.ToString();  //这里取的是指定列的值. 第一列,第六列和第七列 然后做上传
                string parentId = spreadsheetControl1.ActiveWorksheet.Cells[i, ].Value.ToString();
                string parentName = spreadsheetControl1.ActiveWorksheet.Cells[i, ].Value.ToString();
                string ip= "192.168.1.115";
                //}
                string url = "xxxxxxxxxx" + parentName;
                string data =""/;
                string result = HttpPost(url, data);
                 if(result=="ok")
                {
                  //  successcount++;
                    successcountEvent(this, e);
             //       btnupsuccount.Text= successcount.ToString();
                }
                else if(result == "fail")
                {
                    //    failedcount++;
                    failedcountEvent(this, e);
           //         btnfailedcount.Text = failedcount.ToString();
                }

            }
        }

总结:由于数据倒入到spreadsheetControl1  显示在窗体中没有实际操作,占用了资源.在上传时有卡顿现象,卡顿也有其他原因.总之这种是现实方式方式不值得推荐.

二:文件文件名加载到gridcontrol中 ,显示进度的方式
