Code Inspection: Empty 'for' loop is redundant

If a for loop contains no instructions, and its initialization, condition, and iteration do not use variables from the outer scope, ReSharper suggests removing this loop, for example:

          
public void MyMethod()
{
    for (int i=0; i < 100; i++)
    { }
}

    

Note, however, that a for loop with an empty body could be actually used to iterate through external variables, in which case ReSharper will not highlight it as redundant, for example:

          
public void MyMethod()
{
    int a;
    var b = 0;
    for (a=0; a < 100; b += a++)
    { }
    Console.WriteLine("b = " + b);
}
