accessing a variable

[Phil Townsend]

I have a class that contains three local variables. I need to write a
method that updates one of these at a time based on a condition. I would
like to do this without writing a bunch of redundant code. For a very
simplified example:

private string x,y,z;

private void update(DayOfWee k d, int t)
{
switch(d)
{
case d.Monday:
switch (t)
{
case 1:
//update variable "x"
break;
case 2:
//update variable "y"
break;
}
case d.Tuesday:
switch (t)
{
case 1:
//update variable "x"
break;
case 2:
//update variable "y"
break;
}
// ...and so on for the remaining days of the week
}
}

I want to be able to simply call another method in order to eliminate
the nested switch block, but am unsure about how to go about this.

Can anybody help me? Thanks!

Re: accessing a variable

Phil,

Why not just pass the variable that you want modified by ref, instead of
t? Then all you need is one switch statement, and you just update the
variable appropriately.

Hope this helps.

Re: accessing a variable


Here is a better example of what I want to do.

foreach (TimeEntry t in TimeEntries)
{
_Total += t.Duration;
switch (_Categories[t.CategoryId].CategoryType)
{
case 0:
_DirectTotal += t.Duration;
AddTime(ref DirectEntries, t);
switch (t.DateCreated. DayOfWeek)
{
case DayOfWeek.Frida y:
_DirectFridayTo tal += t.Duration;
break;
case DayOfWeek.Monda y:
_DirectMondayTo tal += t.Duration;
break;
case DayOfWeek.Satur day:
_DirectSaturday Total += t.Duration;
break;

// and so on for the reaminder of the week

default: break;
}
break;
case 1:
_IndirectTotal += t.Duration;
AddTime(ref IndirectEntries , t);
switch (t.DateCreated. DayOfWeek)
{
case DayOfWeek.Frida y:
_IndirectFriday Total += t.Duration;
break;
case DayOfWeek.Monda y:
_IndirectMonday Total += t.Duration;
break;
case DayOfWeek.Satur day:
_IndirectSaturd ayTotal += t.Duration;
break;

// and so on for the reaminder of the week

default: break;
}
break;
}
}

I am trying to figure out a way to avoid all the nested switch blocks
and how to figure out which variable to update... thx!

Well, for starters, why have separate fields for _DirectFridayTo tal,
_DirectMondayTo tal, etc. Why not have:

private int[] _DirectTotals = new int[7];

then you can do this:

this._DirectTot als[t.DateCreated.D ayOfWeek] += t.Duration;
