Answer 1

使用BitConverter.GetBytes(long)或BitConverter.GetBytes(ulong)

Answer 2

您可以将其转换为字符串并使用ToCharArray方法。

char [ ] c = a.ToString().ToCharArray();

Answer 3

In C# there is no such thing as char[8] . An array of char would be char[] .

I guess you are coming at this from a C++ viewpoint and actually want an array of bytes, of length 8. In which case the type you need is byte[] . Note that you want byte[] rather than char[] since char in C# is a 16 bit data type.

You can obtain what you need by calling BitConverter.GetBytes() . When you call this function passing an 8 byte integer, the returned array will be a byte[] with length equal to 8, as stated in the documentation .

Answer 4

int a = 123412;

char[] d = a.ToString().ToCharArray();

foreach (char c in d)
{
    Console.WriteLine(c);
}
