如何遍历DataTable单元格

Question

我需要获取DataTable中所有单元格的计数，我该怎么做？我需要这个来验证我的2个表在将数据插入数据库之前具有相同的单元格数量。

Answer 1

试试这个：

    DataTable dt1 = new DataTable(), dt2 = new DataTable();

    // define and populate your tables

    int count1 = dt1.Columns.Count * dt1.Rows.Count;
    int count2 = dt2.Columns.Count * dt2.Rows.Count;

    bool verified = count1 == count2;

Answer 2

 DataTable tbl = new DataTable();
 foreach (DataRow row in tbl.Rows)
 {
   foreach (DataColumn col in tbl.Columns)
   {
     object cellData = row[col];
   }
 }
