For - ForEach

For

for (int icount = 2; icount <= 20; ivalue++) 
{ 
   break;  //terminates the closest ending loop or switch 
} 

For icount = 1 to 20  'the variable is automatically declared  

Next icount 

For icount As Integer = 1 to 20  'the variable is declared on the same line  

Next icount 

Dim icount As Integer   'the variable is declared earlier  
For icount = 1 to 20 

Next icount 

ForEach

If you are iterating through anything that is not a collection you should always use a for loop. It is a lot more efficient than a foreach loop.

foreach (System.Windows.Forms.DataGridViewRow objRow in objDataGridView.Rows) 
{ 

} 

Dim objRow As System.Windows.Forms.DataGridViewRow 
For Each objRow In objDataGridView.Rows 

Next objRow 

ForEach (reverse)

for (icount = 20; icount > -1; ivalue--) 
{ 

} 

For icount As Integer = 20 to 1 Step -1 

Next icount 

Continue

The continue statement transfers execution to the next iteration within the loop

for (int icount = 2; icount <=10; icount++) 
{ 
   if (icount = 6) { 
      continue; 
   } 
} 

For icount As Integer = 2 To 10 
   If (icount = 6) Then 
       Continue For 
   End If 
Next
