Question

因为我想将4个数据集合并到一个datagridview中。所有4个数据集都包含相同的数据模式。

 dgvReport.Rows.Clear();
 DataSet dsResult = objWSX.SelectTopUpReportByCounter(AYear, 
 optCurrency.SelectedValue.ToString());
 DataSet dsResult2 = objWSX.SelectHUGOOnlineTopUpSummary(AYear, 
 optCurrency.SelectedValue.ToString());
 DataSet dsResult3 = objWSX.SelectManjalinkTopUpSummary(AYear, 
 optCurrency.SelectedValue.ToString());
 DataSet dsResult4 = objWSX.SelectReloadCardTopupSummary(AYear, 
 optCurrency.SelectedValue.ToString());

我希望输出如下：

例如：

          terminal_name        jan     feb    march   april   may
         -----------------------------------------------------
 (dataset1) terminal A          100   200    300      500     700  
 (dataset2)  Counter2           50    120    320      780     600
 (dataset3)   ABC               90    12     45       78       60
 (dataset4)   XYZ               X      X     X         X      X

你们可以帮帮我吗？谢谢！

DataSet ds1 = new DataSet（）;
          DataSet ds2 = new DataSet（）;
          DataSet ds3 = new DataSet（）;
          DataSet ds4 = new DataSet（）;


ds2.Merge（DS1）;
        ds3.Merge（DS2）;
        ds4.Merge（DS3）;

Answer 1

DataSet ds1 = new DataSet();
DataSet ds2 = new DataSet();

ds2.Merge(ds1);
Gridview.DataSource = ds2;
