Try:
int i = Convert.ToInt32(dt.Rows.Count);
I think it's the shortest, thus the simplest way.
You have two options here.
The individual row simply represents data, so it will not know what row it is located in.
ArrayList check = new ArrayList();
for (int i = 0; i < oDS.Tables[0].Rows.Count; i++)
{
int iValue = Convert.ToInt32(oDS.Tables[0].Rows[i][3].ToString());
check.Add(iValue);
}
Why don't you try this
for(int i=0; i < dt.Rows.Count; i++)
{
// u can use here the i
}
If you need the index of the item you're working with then using a foreach
loop is the wrong method of iterating over the collection. Change the way you're looping so you have the index:
for(int i = 0; i < dt.Rows.Count; i++)
{
// your index is in i
var row = dt.Rows[i];
}
You do know that DataRow is the row of a DataTable correct?
What you currently have already loop through each row. You just have to keep track of how many rows there are in order to get the current row.
int i = 0;
int index = 0;
foreach (DataRow row in dt.Rows)
{
index = i;
// do stuff
i++;
}
