DataTable dt = SomeMethodReturnDataTable();
YourDataSet ds = new YourDataSet();

将DataTable添加到DataSet中:

Add DataTable into DataSet:

ds.Tables.Add(dt)

或如果ds.Tables["A"]中的列与dt相同，则可以循环各行和列，并将dt中的值加载到ds.Tables["A"]中.

or If the columns inside ds.Tables["A"] is same with dt, then you can loop each rows and columns and load the value from dt into ds.Tables["A"].

int c = -1;
foreach (DataRow dr in dt.Rows)
{
    c++;
    ds.Tables["A"].Rows.Add();
    foreach (DataColumn dc in dt.Columns)
    {
        ds.Tables["A"].Rows[c][dc.ColumnName] = dr[dc.ColumnName];
    }
}
