Hi,

I am trying to make a C# AIS decoder. I am using this information a a base point http://www.bosunsmate.org/ais/[^]

I have managed to get the binary of each character, but I do not know how to convert it into its correct format now. For example, the MMSI binary is '010010110101011101110000101001'. I am getting this value, but how do I decode it and get the value '316005417' from it?

Try explaining exactly what you are trying to do (post your code, don't expect everyone to follow the link), and what results you receive compared to those you expect, and people will try to help.

Having a look at my answer to your last request Convert 8bit ASCII to 6bit[^]
and probably having a look at

convert.ToInt32()

and its 18 overloads might have lead you to

Convert.ToInt32(< your binary value >, 2)

No, it should decode into a string

then add .toString()

Why do you down vote my answer? Just because you don't like it?

Um...because it doesnt make sense!! Binary can represent text! For example, '101101' could be decoded into 'e' Sayint Convert.ToInt32('101101').ToString() is going to do absolutely nothing!!!

You asked on how to decode e.g. (bin)'010010110101011101110000101001' into (int)316005417. And that's what Convert.ToInt32('010010110101011101110000101001',2) is doing.
And Convert.ToInt32('010010110101011101110000101001',2).toString() will return (string)'316005417'.
