c# - 如何使用 C# 'foreach' DataTable 中的列？

Question

如何使用 foreach 遍历数据行中的每一列？

DataTable dtTable = new DataTable();
MySQLProcessor.DTTable(mysqlCommand, out dtTable);

foreach (DataRow dtRow in dtTable.Rows)
{
    //foreach(DataColumn dc in dtRow)
}

Answer 1

这应该有效:

DataTable dtTable;

MySQLProcessor.DTTable(mysqlCommand, out dtTable);

// On all tables' rows
foreach (DataRow dtRow in dtTable.Rows)
{
    // On all tables' columns
    foreach(DataColumn dc in dtTable.Columns)
    {
      var field1 = dtRow[dc].ToString();
    }
}
