nyI'm looking for a way to convert a string of binary to a hex string.

the binary string has four positions. the binary string looks something like this

string binarystring= "1011";

output string should be like this

output string="B";

is there any way to convert a string of binary into hex?

Solution

Convert.ToInt32("1011", 2).ToString("X");

For more information about the string value used with ToString() as its parameter, check the following documentation:
