Iterate through DataSet
提问by user902949
I have a DataSetnamed DataSet1. It contains an unknown number of tables and an unknown number of columns and rows in those tables. I would like to loop through each table and look at all of the data in each row for each column. I'm not sure how to code this. Any help would be appreciated!
我有一个DataSet名为DataSet1. 它包含未知数量的表以及这些表中未知数量的列和行。我想遍历每个表并查看每列每行中的所有数据。我不知道如何编码。任何帮助，将不胜感激！

Just loop...
只是循环...
foreach(var table in DataSet1.Tables) {
foreach(var col in table.Columns) {
...
}
foreach(var row in table.Rows) {
object[] values = row.ItemArray;
...
}
}

foreach (DataTable table in dataSet.Tables)
{
foreach (DataRow row in table.Rows)
{
foreach (object item in row.ItemArray)
{
// read item
}
}
}
Or, if you need the column info:
或者，如果您需要列信息：
foreach (DataTable table in dataSet.Tables)
{
foreach (DataRow row in table.Rows)
{
foreach (DataColumn column in table.Columns)
{
object item = row[column];
// read column and item
}
}
}
