I'm getting a value from DataGridView, and based on particular I want to know its row index using DataTable object. For instance, if I get the value "this", then I want to know its index in table. May I know how should I done

推荐答案

如果该值this"属于 DataTable 中的 Non-Primary-Key Column，您可能会返回多于一行.

If that value "this" belongs to a Non-Primary-Key Column in DataTable, you may get more than one rows returned.

要在 DataTable 中查找值，请使用 DataTable 的 Select() 方法:

To find a value in DataTable, use DataTable's Select() method:

DataRow[] rows = dt.Select("Column1 = 'this'");

获得行后，您可以使用 DataTable.Rows.IndexOf() 方法找到其索引.

Once you get the row(s), you can find its index using DataTable.Rows.IndexOf() method.

我建议您找到一种更好的方法来从 DataTable 中定位您的行.可能会使用属于 Primary Key Column 的值查找行.

I suggest you find a better way to locate your row from DataTable. May be look for row using a value that belongs to a Primary Key Column.

很高兴知道您为什么要这样做.有人可以想出更好的解决方案.

It would be great to know why you want to do this. Someone could come up with a better solution.
