I have a large amount of nested foreach loops and I'm running out of variable names to use... Could I do something like this :
//int i = 1
string "number"+i = new String("FirstElement");
I've seen some posts about this for languages such as C and javascript, but I don't know how to do it in C#.
In case you can't name variables after other variables : how could this problem otherwise be solved?
This problem could otherwise be solved by using meaningful variable names - running out of names would mean running out of concepts for what the thing is trying to achieve, which is hard to believe.
If your requirement is to work with a collection of variables, then put them in a collection; if it's to have n number of variables all strictly defined by name, then name them explicitly, and so on.
var a = new List<int>();
for(int i=0;i<100;i++)
{
a.Add(i);
}
Console.WriteLine(a[0]);
Console.WriteLine(a[1]);
etc....
This way you make list which contains 100 elements, you can access them by nameoflist[index]
foreach(var something in yourmagiclist) { a.Add(something.SomeProperty); } of course a must be a list of same type as SomeProperty
A while back I asked a similar question:
Python - neat way of creating multiple objects?
Basically, if you have lots of very similar variables named things like variable_1, variable_2, etc, then thats normally a sign that you should be using an array or list of variables instead.
So instead of 10 separate string variables, create a list (or array) of strings.
The way you are doing will not work in C#. You can not create variables at run time. If you want you have to use a list to store your variable name and value. Therefore you better create a class to hold name of the variable and value.
class Variable
{
string Name;
string Value;
}
Now create another class to hold variables
class VaraibleHolder
{
List<Variable> Variables;
VariableHolder()
{
Variables = new List<Variables>();
}
public void Add(Variable Vbl)
{
Variable vbl = Variables.SingleOrDefault(v=>v.Name == Vbl.Name);
if(vbl == null)
{
Variables.Add(vbl);
}
}
public void Remove(string VblName)
{
//this is a lamda expression.
Variable vbl = Variables.SingleOrDefault(v=>v.Name == VblName);
if(vbl != null)
{
Variables.Remove(vbl);
}
}
public Variable GetVariable(string VblName)
{
Variable vbl = Variables.SingleOrDefault(v=>v.Name == VblName);
return vbl;
}
}
So you can use Variable holder to create and store varaibles at runtime. Hope this will help you.
