DataSet.Tables is of type DataTableCollection[^]. If you call ToString() on that, you get the default ToString()-implementation which just gives you the type name.

As DataTableCollection doesn't implement IEnumerable<> (which would allow you to call .Select(table => table.TableName) on it) your only option is to loop over the contained tables (either with a for-loop or a foreach-loop), add the names of the tables to a List<string> and then add the items in that list to your ListBox with .AddRange(..).

Hi, change your code like this,

C#

for(int i = 0; i < mydataSet.Tables.Count; i++)
{
   listBox.Items.Add(mydataSet.Tables[i].TableName);
}
