Go to this link for example For Loop: In case of for the variable of the loop is always be int only. The For Loop executes the statement or block of statements repeatedly until specified expression evaluates to false. There is need to specify the loop bounds(Minimum, Maximum). Foreach loop : In case of Foreach the variable of the loop while be same as the type of values under the array. The Foreach statement repeats a group of embedded statements for each element in an array or an object collection. You do not need to specify the loop bounds minimum or maximum.
