Put a break-point on 'foreach (ListViewItem item in ListView1.Items) and run the program: examine the value of ListView1.Items. What do you find ?

Solution 1

First of all.. this kind of problems are easily seen debugging your code step by step. We can't see the rest of the code,so it's impossible for us knowing what's wrong.

That said,i'll try to guess. If the foreach is not executed,there are 2 options: Or ListView1 has no items,or maybe is null. I guess is the first one, so check how you bind data to your listview1.

[EDIT]

Ok..now i look at it,i don't think your code even compiles! Try this

C#

foreach (ListViewItem item in ListView1.Items)
{
string productDescription = item.Text;
string p1 = item.SubItems[1].Text;
 

string p2 = item.SubItems[2].Text;
string p3 = item.SubItems[3].Text;
string p4 = item.SubItems[4].Text;
string p5 = item.SubItems[5].Text;
 
string productLine = productDescription;
....

You can´t assing an item to a string variable, you must assign the text property of the item.
