How to get the row number from a datatable?

Question

I am looping through every row in a datatable:

foreach (DataRow row in dt.Rows) {} 

I would like to get the index of the current row within the dt datatable. for example:

int index = dt.Rows[current row number] 

How do i do this?

Answer 1

int index = dt.Rows.IndexOf(row); 

But you're probably better off using a for loop instead of foreach.

Answer 2

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]; }
