Why numbers converted from char to int are different than before conversion?-CodePudding

so, as the title says, I can't convert numbers from char to integer. Am I doing something wrong?

Console.Clear();
int hourBin1 = 0, hourBin2 = 0, minuteBin1 = 0, minuteBin2 = 0, secondBin1 = 0, secondBin2 = 0;
int iteration=0;
void conversion(int variable){
    int i=0;
    int[] table = new int[6];
    while(variable>0){
        table[i]=variable%2;
        Console.WriteLine($"{i} {variable} {table[i]}");
        variable/=2;
        i  ;
    }
    int result = 0;
    for(int j=i-1;j>=0;j--){
        result*=10;
        result =table[j];
    }
    if(iteration==0){
        hourBin1=result;
        iteration  ;
    }else if(iteration==1){
        hourBin2=result;
        iteration  ;
    }else if(iteration==2){
        minuteBin1=result;
        iteration  ;
    }else if(iteration==3){
        minuteBin2=result;
        iteration  ;
    }else if (iteration==4){
        secondBin1=result;
        iteration  ;
    }else if (iteration==5){
        secondBin2=result;
        iteration  ;
    }
}
Console.Write("enter date in HH:MM:SS format to convert: ");
string numberString = Console.ReadLine()!.Trim();
char[] separation = numberString.ToCharArray();
foreach (var x in separation){
    Console.Write($"{x} ");
}
int hour1 = Convert.ToInt16(separation[0]);
int hour2 = Convert.ToInt16(separation[1]);
int minute1 = Convert.ToInt16(separation[3]);
int minute2 = Convert.ToInt16(separation[4]);
int second1 = Convert.ToInt16(separation[6]);
int second2 = Convert.ToInt16(separation[7]);
Console.WriteLine("converting to binary system");
conversion(hour1);
conversion(hour2);
conversion(minute1);
conversion(minute2);
conversion(second1);
conversion(second2);
Console.WriteLine($"\n{hour1} {hour2} {minute1} {minute2} {second1} {second2}");
Console.WriteLine($"hourBin1}\n{hourBin2}\n{minuteBin1}\n{minuteBin2}\n{secondBin1}\n{secondBin2}");

for example:

console outputs for "12:23:34" looks like this:

1 2 : 2 3 : 3 4 49 50 50 51 51 52

I want it to look like this :

1 2 : 2 3 : 3 4 1 2 2 3 3 4

and final output looks like this:

49 50 50 51 51 52 110001 110010 110010 110011 110011 110100

I want it to look like this :

1 2 2 3 3 4 0001 0010 0010 0011 0011 0100

PS for some reason, table cant take value smallet than 6, any ideas why?

CodePudding user response：

There are basically the equivalent ASCII values, all you can do is simply subtract 48 from each value then you will get the exact value. ASCII value of char 1 is 49.

int hour1 = Convert.ToInt16(separation[0]) - 48;
