How to iterate all items in a given row in the DataTable

How to iterate all items in a given row in the DataTable . I have the following code to iterate all rows, I want another For loop to iterate all cells in a given row ?

For Each row As DataRow In dt.Rows

Next row

I can access each row, but I want to access each column on the row, as I don’t know the name and the count of the columns ,..

Method 1

You have to loop through DataRow.ItemArray. In C#, we can do it by following code:

 foreach (DataRow dr in dt.Rows)
   {
     foreach (var item in dr.ItemArray)
       {
                Console.WriteLine(item);
       }
   }

This is equivalent to the following VB.NET code.

For Each dr As DataRow In dt.Rows
    For Each item In dr.ItemArray
        Console.WriteLine(item)
    Next
Next

Method 2

For Each row As DataRow In dt.Rows
    For Each column As DataColumn in dt.Columns
        Console.WriteLine(row(column))
    Next column
Next row

Method 3

your code is correct.
you cn use this code…

Dim tbl As New DataTable()
Dim datarow As DataRow

tbl.Columns.Add("column1")

datarow = tbl.NewRow()
datarow("column1") = "Data1"

tbl.Rows.Add(datarow)
For Each dr As DataRow In tbl.Rows
    For Each value In dr.ItemArray
       Label1.Text = value.ToString()
    Next
Next

Method 4

You can use DataRow.ItemArray to do the job also

the code would look something like this

For Each item As var In Row.ItemArray
    //do something
Next
