C# -- "foreach" ?

The first "foreach" below works.

What do I need to put in the below
"what here ??" section so the
second "foreach" works ?
---------------------------------------------------
DataSet ds = new DataSet("Temp");
adapter.Fill(ds);

// Loop through the data table and change names like "Doe,John" to "John Doe"
foreach (DataRow row in ds.Tables[0].Rows)
    row[0] = Regex.Replace((string)row[0], @"([^,]*),([^,]*)", "$2 $1");

// Loop through the data table and change blanks to "0"
foreach (DataRow row in ds.Tables[0].Rows)
    row[5] = what here ??;

return ds;

this said, I would avoid the second loop:
foreach (DataRow row in ds.Tables[0].Rows)
{
   row[0] = Regex.Replace((string)row[0], @"([^,]*),([^,]*)", "$2 $1");
   if ( row[5] == "" ) { row[5] = "0"; }
}

what about:

foreach (DataRow row in ds.Tables[0].Rows)
{  if ( row[5] == "" ) { row[5] = "0"; }
}

This should also work:
foreach (DataRow row in ds.Tables[0].Rows)
{
   row[0] = Regex.Replace((string)row[0], @"([^,]*),([^,]*)", "$2 $1");
   row[5] = row[5].Replace("","0");
} 
//Or if you are worried that row[5] may be null then
foreach (DataRow row in ds.Tables[0].Rows)
{
   row[0] = Regex.Replace((string)row[0], @"([^,]*),([^,]*)", "$2 $1");
   if(row[5] == null)
       row[5] = "0";
   else
       row[5] = row[5].Replace("","0");
}

>row[5].Replace("","0");

I don't think that that will really work ?!

Try this:

Change this line:
    row[5] = what here ??;

like this:
    row[5] = String.IsNullOrEmpty(row[5]) ? "0" : row[5] ;
