如何迭代DataTable單元格

Question

我需要獲取DataTable中所有單元格的數量，我該怎麼做？我需要這個來驗證我的2表格在將數據插入數據庫之前具有相同的單元數量。

Answer 1

試試這個：

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]; 
    } 
}
