Conversion of Char to Int32 giving confusing results
In the debugger, c is equal to '4' which I expected. But charAsInt equals 52 after the line runs, instead of 4. It seems to be picking up the ASCII value not the raw integer value (is my guess).
How do I get a char of '4' to be converted to an int of 4?
How do I get a char of '4' to be converted to an int of 4?
string cardnumber = "400006400017"
foreach (char c in cardnumber)
{
int charAsInt = Convert.ToInt32(c); // in debugger, c is equal to '4' which I expected. But charAsInt equals 52 after this line runs, instead of 4.
if (((charAsInt % 2) == 0))
{
runningSum += charAsInt * 3;
}
else
{
runningSum += charAsInt * 1;
}
}
Try this?
string cardnumber = "400006400017"
foreach (char c in cardnumber)
{
int charAsInt = (int)c; // in debugger, c is equal to '4' which I expected. But charAsInt equals 52 after this line runs, instead of 4.
if (((charAsInt % 2) == 0))
{
runningSum += charAsInt * 3;
}
else
{
runningSum += charAsInt * 1;
}
}
