I have tried

C#

DataTable updateddataTable=new DataTable();
foreach( DataTable dataTable in dataSet)
{
foreach(DataRow dr in dataTable.Rows)
{
   for(int i=0;dataTable.Columns.Count;i++)
{
row[i]=HttpEncode(row[i]);
}
updateddataTable.ImportRow(row);
}

The updated datatble getting null here could you please suggest better approach for this.
That should be work without loss any data from dataset

Can't you do that upstream? If you're filling the datasets by querying a database, you may be able to add the encode to the query.

Take a look at below code:

C#

//create another dataset object
DataSet ds = new DataSet();
//loop through the tables in original dataset
foreach(DataTable origDt in origDataSet)
{
    //create new datatable and clone structure
    DataTable encodedDt = origDt.Clone();
    //loop through the rows in original datatable and import encoded row into "encoded" table
    for(int i=0; i<origDt.Rows.Count; i++)
    {
        DataRow dr = origDt.Rows[i];
        encodedDt.ImportRow(HttpEncode(dr));
    }
    //add datatable to "another" dataset
    ds.Tables.Add(encodedDt);
}
//done!
//you can use [ds] now
