代码是Java转过来的,变量名都没有改……有空再整理一下好了。
public long toDecimal(string input, long bs)
{
try
{
long Bigtemp = 0, temp = 1;
int len = input.Length;
for (int i = len - 1; i >= 0; i--)
{
if (i != len - 1)
temp *= bs;
long num = changeDec(input[i]);
Bigtemp += temp * num;
}
return Bigtemp;
}
catch
{
return 0;
}
}
//十进制转换中把字符转换为数
static int changeDec(char ch)
{

if (ch >= 'A' && ch <= 'Z')
num = ch - 'A' + 10;
else if (ch >= 'a' && ch <= 'z')

return num;
}
//数字转换为字符
