Vb.Net Dataset table = New DataTable

问题

I came across one programming issue that I have tried to solve it as follows:

dsDataSet.Tables("promotion") = New DataTable.

But Unfortunately this does not work because error: property 'Item' is read only

Is there away to accomplish this?

回答1:

The Tables collection of a DataSet could be modified using the Add, Remove methods

dsDataSet.Tables.Add(new DataTable("promotion"))

of course, the line above requires that the collection doesnt already contain a table named "promotion". If you have already a table named "promotion" in your dataset then you need to remove it before adding the new one

dsDataSet.Tables.Remove("promotion")
dsDataSet.Tables.Add(new DataTable("promotion"))
