Use static methods in Path

image_pdfimage_print
   
  

using System;
using System.Diagnostics;
using System.IO;
class TestPathApp {
    static void Main(string[] args) {
        Process p = Process.GetCurrentProcess();
        ProcessModule pm = p.MainModule;
        string s = pm.ModuleName;

        Console.WriteLine(Path.GetFullPath(s));
        Console.WriteLine(Path.GetFileName(s));
        Console.WriteLine(Path.GetFileNameWithoutExtension(s));
        Console.WriteLine(Path.GetDirectoryName(Directory.GetCurrentDirectory()));
        Console.WriteLine(Path.GetPathRoot(Directory.GetCurrentDirectory()));
        Console.WriteLine(Path.GetTempPath());
        Console.WriteLine(Path.GetTempFileName());
    }
}

   
     


Path.GetTempFileName

image_pdfimage_print
   
  
using System;
using System.IO;

class MainClass {
    static void Main() {
        string tempFile = Path.GetTempFileName();

        Console.WriteLine("Using " + tempFile);

        using (FileStream fs = new FileStream(tempFile, FileMode.Open)) {
            // (Write some data.)
        }

        // Now delete the file.
        File.Delete(tempFile);

    }
}

   
     


Paths in C#

image_pdfimage_print
   
  
/*
s = new FileStream("C:	empGoo.txt", FileMode.Create);

or use forward (Unix-style) slashes:

s = new FileStream("C:/temp/Goo.txt", FileMode.Create);

or use the at sign (@), which is a control-character suppressor:

s = new FileStream(@"C:	empGoo.txt", FileMode.Create);
*/

Use MemoryStream and BinaryReader to convert Byte array to decimal

image_pdfimage_print


   
 
using System;
using System.IO;

class Test {
    public static byte[] DecimalToByteArray (decimal src) {
        using (MemoryStream stream = new MemoryStream()) {
            using (BinaryWriter writer = new BinaryWriter(stream)){
                writer.Write(src);
                return stream.ToArray();
            }
        }
    }

    public static decimal ByteArrayToDecimal (byte[] src) {
        using (MemoryStream stream = new MemoryStream(src)) {
            using (BinaryReader reader = new BinaryReader(stream)) {
                return reader.ReadDecimal();
            }
        }
    }

    public static void Main() {
        byte[] b = BitConverter.GetBytes(true);
        // Convert a decimal to a byte array and display.
        b = DecimalToByteArray(12345678987654321.563846696m);
        Console.WriteLine(BitConverter.ToString(b));

        // Convert a byte array to a decimal and display.
        Console.WriteLine(ByteArrayToDecimal(b));
    }
}
