I have a lot of Int32
variables that I wanted to select which int
I want to check. Is it possible to make this line and select an variable using multi variables?
Int32 redleft0 = 0;
Int32 redleft1 = 0;
Int32 redleft2 = 0;
Int32 redleft3 = 0;
Int32 redleft4 = 0;
Int32 redleft5 = 0;
Int32 blueleft0 = 0;
Int32 blueleft1 = 0;
Int32 blueleft2 = 0;
Int32 blueleft3 = 0;
Int32 blueleft4 = 0;
Int32 blueleft5 = 0;
redorblue = "red";
for (int i = 0; i < count; i++)
{
String checkleftint = (redorblue + "left" + i);
if (checkleftint < 0)
{
}
}
You should use an array - or rather two - here:
var red = new int[]{0,0,0,0,0,0};
var blue = new int[]{0,0,0,0,0,0};
var arrayToUse = redorblue == "red" ? red : blue;
for (int i = 0; i < count; i++)
{
var value = arrayToUse[i];
// ....
}
将数组或字典与键和值一起使用,以便可以使用键提取值
It won't work that way. Either don't use separate variables but use an array:
int[,] vars = new int[2,6] { { 0, 0, 0, 0, 0, 0 }, { 0, 0, 0, 0, 0, 0 } };
// int[0,*] would be redleft and int[1,*] would be blueleft
or use a Dictionary<string, int>
It's possible if you use enum , for example:
enum values { redleft0 = 0; redleft1 = 120; redleft2 = 13; }
By using enum
So what you wolud do is just:
for (int i = 0; i < count; i++)
{
if(i == values.redLeft0){
...
}
}
By using enum
, you associate a name you want to a number you want.
If this is not what you're asking for, please clarify.
