.NETUlong到二进制字符串表示？[重复]-.NETUlongtobinarystringrepresentation?[duplicate]

Well, you could write Convert.ToString((long)value, 2);

好吧，你可以编写Convert.ToString（（long）value，2）;

Casting a ulong to long doesn't change the bit pattern at all.

将ulong转换为long不会改变位模式。

As I recall, there are no Convert methods to deal with UInt64 or UInt32 because Convert is intended to be CLS Compliant, and public methods that deal with unsigned values aren't CLS Compliant.

我记得，没有转换方法来处理UInt64或UInt32，因为转换是CLS兼容的，处理无符号值的公共方法不符合CLS。

See Common Language Specification.

请参阅公共语言规范。

This does not change the bit pattern. Consider:

这不会改变位模式。考虑：

ulong foo = 0x7FFFFFFFFFFFFFFF;
Console.WriteLine(Convert.ToString((long) foo, 2));

foo = 0x8000000000000000;
Console.WriteLine(Convert.ToString((long)foo, 2));

The output is:

输出是：

111111111111111111111111111111111111111111111111111111111111111
1000000000000000000000000000000000000000000000000000000000000000

Note that the first line has 63 bits. The high bit is 0. The second line has 64 bits. The high bit is set correctly.

注意，第一行有63位。高位为0.第二行有64位。高位设置正确。
