Convert C# data types to c++ data types

Expand Post »

Hi,

I have a legacy application in vc++ 6.0 which communicates to a server. The server follows c++ data types. I want to convert my legacy application to c#. Now I am facing some conversion issues. The server accepts data in binary format. But when I declare a char data type in C# it takes 2 bytes, whereas char data type in c++ takes 1 byte. How do I convert the char in c# so that it is 1 byte.

Re: Convert C# data types to c++ data types

C# has byte and sbyte types depending on if you care about the sign or not.

Re: Convert C# data types to c++ data types

If you want you can change the size of the char to 1 byte too.

I don't really know how, but some detail might be in the specification or MSDN
this might help http://msdn.microsoft.com/en-us/libr...ar(VS.80).aspx

Re: Convert C# data types to c++ data types

Char is 2 byte in .NET because that is how big a Unicode character is. The best thing to do is take the value in as a byte datatype and use the Convert.ToChar() method on that input value.

I just tried it with this code, and you'll see it produces an "H":

C# Syntax (Toggle Plain Text)
using System;
 
namespace Unicode_test
{
    class Program
    {
        static void Main(string[] args)
        {
            byte myByte = 0x48; // 'H' in ASCII, single byte
            char myChar = Convert.ToChar(myByte); // should still be 'H"
            Console.WriteLine(myChar);
            Console.ReadLine();
        }
    }
}
using System;

namespace Unicode_test
{
    class Program
    {
        static void Main(string[] args)
        {
            byte myByte = 0x48; // 'H' in ASCII, single byte
            char myChar = Convert.ToChar(myByte); // should still be 'H"
            Console.WriteLine(myChar);
            Console.ReadLine();
        }
    }
}
