How to perform the below mentioned task(vb.net)?

Question

Dim cells = From Qmaxminslist As DataGridViewRow In DataGridView2.Rows.Cast(Of DataGridViewRow)() Take Integer.Parse(daysamaxminsmv.Text)

For Each row As DataGridViewRow In cells
   // piece of code...
Next

I have converted this code in C# as:

dynamic cells = from Qmaxminslist in DataGridView2.Rows.Cast<DataGridViewRow>() select (int.Parse(daysamaxminsmv.Text));

foreach (DataGridViewRow row in cells)
{
    // piece of code...
}

but here comes an exception in the foreach statement saying:

"Cannot convert type 'int' to 'System.Windows.Forms.DataGridViewRow'"

how to solve it? any help will be appreciated. Thanks

You haven't converted it correctly. The VB code selects DataGridViewRows, the C# code selects ints. You want to take N rows. VB.NET supports Enumerable.Take directly in the LINQ query, C# does not support it. So i'd use method syntax in C#.

So this works as desired (don't translate Dim with dynamic but var):

int takeRows = int.Parse(daysamaxminsmv.Text);
var rows = DataGridView2.Rows.Cast<DataGridViewRow>().Take(takeRows);

foreach (DataGridViewRow row in rows)
{
    // piece of code...
}
