Solution 3

Edited:

C#

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

Add DataTable into DataSet:

C#

ds.Tables.Add(dt)

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"].

C#

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];
    }
}

Hi Adriancs thanks for the reply...This is what i wanted.But when i am assigning "ds.Tables["A"] = dt" , iam getting the following error
Property or indexer 'System.Data.DataTableCollection.this[string]' cannot be assigned to -- it is read only
