What is the difference between these two methods when binding data? ?

One:
da.fill (ds);
this.dg.DataSource = ds;

two:
da.fill (ds, "tab");
this.dg.DataSource = ds.Table ["tab"];

What is the difference between the two, which is better? ?

No difference, just add a table name
If there are multiple tables in a dataset
You can add an alias to each table inside to distinguish

If a table is accessed using dataset.Table [0], the effect is the same
