如何在C#中将大二进制字符串转换为Hexa十进制字符串格式？

Question

我正在尝试将二进制数据(字符串)转换为十六进制数据(字符串)

 string BinaryData = 1011000000001001001000110100010101100111100000000001000001111011100010101011";

 string HexaDecimalData = Convert.ToInt64 ( BinaryData, 2 ).ToString ( "X" );

我得到一个OverflowException : Value was either too large or too small for a UInt64. 我可以理解二进制字符串很大,但同时我不能想到比Int64更大的数据类型.

有什么建议？

string BinaryData = "1011000000001001001000110100010101100111100000000001000001111011100010101011";

int count = 0;
var hexstr = String.Concat(
                BinaryData.GroupBy(_ => count++ / 4)
                          .Select(x => string.Concat(x))
                          .Select(x => Convert.ToByte(x, 2).ToString("X"))
             );
