我们可以在数据集中存储多少个表？

Question

How many tables we can store in a dataset. How to count the limit of tables in a single dataset

Dataset Ds;
Int x=Ds.max tables;

Answer 1

It's System.Int32.MaxValue so 2,147,483,647 because DataSet.Tables returns a DataTableCollection that has a Count property which is of type System.Int32 .

In practice the memory is the limitation.

But Hans Passant's is right: "if you need to know then you're doing it wrong". So i hope that this is just a theoretical question.

Answer 2

Max size is an Int32. So there are maximum 2.147.483.647 (2 Billion) tables possible.
