ToString()

[Guest]

in C/C++ I can use printf("%0.2X",t) to add mack the output wit to parameter,
for example if t = 0xA after printf I will get 0x0A.
How can I do that in C#.
I want to print a hexa number but to be 4 carecters 0x000A insted of 0xA.
and also I want to print a bin number but to be 8 carecters 00001010 insted of 0xA = (0xA).ToString("B") ???????.

Hi,
I didn't see anything like this on c#, even not on numeric format stings,
But you can try this below for hex, it will give the same result, or you
could take a deep look at Regexp maybe someone did it before.

string out = "0x" + val.ToString("X").PadLeft(4,'0');


Good Luck

Hi

The following code shows an example console application.

/* ---- start of code ---- */
using System;

class hexConversion
{
public static void Main()
{
int myValue = 0;

while( myValue != -1 )
{
Console.Write( "Enter a real number or -1 to exit: " );
myValue = Convert.ToInt32( Console.ReadLine() );

if( myValue != -1 )
{
Console.WriteLine( "Number entered is : {0}", myValue );
Console.WriteLine( "Hex equivalent is : {0:x4}", myValue ); // will
add leading zeros to give four digit answer
Console.WriteLine( "" );
}
}

// Here to stop app from closing
Console.WriteLine( "\n\nPress Return to exit." );
Console.Read();
}
}
/* ---- end of code ---- */

I will add this to my snippets page

Hope this helps
