Question

i have a for each loop inside a for loop, the for each loop checks if a value in some column in the current row exists in an array, if it exists i want to do whats in the for loop and if it doesnt exist i want to continue the for loop

for i = 0 To DataGridView1.RowCount - 1
        For Each id In IDs
            If (DataGridView1.Item(1, i).Value <> id) Then
               'continue the for loop, by continue i mean using continue statement and not executing the outer for loop for this case
            End If
        Next
  'do for loop things
Next

what i am trying to do is to do calculations for the rows that have a specific id and skip the rows with the ids that are not in the array.

Do you want to “do for loop things” only if there is a match? Why not just like this?

For i = 0 To DataGridView1.RowCount - 1 
    doThings = False
   For Each id In IDs
      If (DataGridView1.Item(1, i).Value = id) Then 
        doThings = True
        Exit For
      End If 
  Next 
  If doThings Then 
    ** do for loop things 
  End If 
Next 

Could be improved by creating more methods

• a function to determine whether an id appears in “IDs”. Is it a List? Can you use IDs.Contains()
• a method to “do for loop things”
