Question

I have an Dataset (XSD) with many datatables. How can I get informations about this datatables? for example I want to get all columns and its captions from a specific datatable.
When I use dataset_X.datatable_Y…. there are no properties like “colums” and so on.
I only get “Equals“, “GetDataTableSchema“, “GetTypedSchema” and “Reference Equals“.

You need to create an instance of your strongly typed DataSet.

For example:

var ds = new dataset_X();
DataColumnCollection columns = ds.datatable_Y.Columns;

or, if you want informations of a specific column, you can also use the auto generated property. Assuming there’s a column with a name idSparePart, there’s automatically a property idSparePartColumn.

DataColumn col = ds.datatable_Y.idSparePartColumn;
String columnName = col.ColumName; 
Type t = col.DataType;
// and so on...
