Copy a directory somewhere

Simple question. Smile | :)

Is there a command to copy a directory in a different path without doing this manually on files and sub-directory contained there?
I've not found any copy command on System::IO::Directory ... it's strange! Confused | :confused:

Thank you

Russell

If you wanna move the directory, use Directory.Move

yes...like MS-DOS command xcopy does.
Of course, I can use directly that command, ... but I'm trying to understand if there is an implemented function that does this copy that I still not know.
Thank you

As fas as I know there is not such built-in function but if you search codeproject for xcopy you will find what you need.

Another idea for you is to do a simple hack - use the Process class and start a process using the xcopy command like you mentioned in some of your other posts.

I actually have done this in a build app I wrote.

I've also used the process class for doing FTP and LPR (using the built-in Windows commands, since there are no easy classes in the framework for this).

Hi
I have already wrote about my problem. I have a string that comes from console app

after it i convert it with this procedure

static private string EncodeMessageForConsoleOutput(string Message)
{
//gag
if (MemoLog == null)
return Message;

if (EncodingFrom.CodePage == EncodingTo.CodePage)
return Message;

Decoder decoder = Encoding.UTF8.GetDecoder();
byte[] bytes = Encoding.UTF8.GetBytes(Message);
char[] chars = new char[bytes.Length * 5];//*2

int bytesUsed, charsUsed;
bool completed;

decoder.Convert(bytes, 0, bytes.Length,
chars, 0, chars.Length, true,
out bytesUsed, out charsUsed, out completed);

string ResultString = new string(chars, 0, charsUsed);

return ResultString;
}

but it does not work

Could you help me
what's the problem with this code?

For hours and minutes only, without dates and seconds:

DateTime first;
DateTime second;

if (first.Hour > second.Hour)
{
    //first is later
}
else
    if (first.Hour == second.Hour)
        if (first.Minute > second.Minute)
        {
            //first is later
        }
        else
            if (first.Minute == second.Minute)
            {
                //they are the same
            }
            else
            {
                //second is later
            }
    else
    {
        //second is later

Yu can use the System.TimeSpan class. Quite handy, especially when used in conjunction with System.DateTime.

<br />
DateTime dt1 = DateTime.Parse("2007/06/14 13:24:00");<br />
DateTime dt2 = DateTime.Parse("2007/06/14 12:00:00");<br />
TimeSpan ts = dt1 - dt2;<br />
double elapsed = ts.TotalHours;<br />

This will give you the total number of hours elapsed from dt1 until dt2. If you are rather interested in the total number of minutes that elapsed you can use:
double elapse = ts.TotalMiutes;
or a host of others.

Hi,

if you want to ignore the other fields in a DateTime, you can not easily use the available
functions, nor TimeSpan.

I then suggest something like this:

public static int CompareHourMinuteOnly(DateTime dt1, DateTime dt2) {
    int diff=dt1.Hour-dt2.Hour;
    if (diff==0) diff=dt1.Minute-dt2.Minute;
    return diff;
}

Another way would be to force the 2 DateTime instances to have the same date (hardcode to something like 0001-01-01) and then do a DateTime.Compare(d1, d2);

Hi,

Can any one please give me a script to browse and upload a file to a specific webserver location which should also check the extension of the file ( for eg, css files needs to go into one location and graphics files need to go into another location)

Thank You.

Question on iterators

Dewald14-Jun-07 0:13

So I have a class for which I wrote a nice indexer, making it possible to access the class contents as if it were an array. Some like this:

public class MyClass
{
   protected byte[] buffer;
   protected int size;

   public byte this[int index]
   {
      get
      {
         if (index<0 || index >= size)
            throw new IndexOutOfRangeException();
         return buffer[index];
      }
      set
      {
         if (index<0 || index >= size)
            throw new IndexOutOfRangeException();
         buffer[index] = value;
      }
   }
}

Now I'd like to pass this entire class (the array'ed version so to speak) as a parameter to a function. Say I have a function defined as follows:
public void myFunc (byte[] inbuffer)

Obviously I can't call this function as follows:

MyClass myInstance = new MyClass();<br />
myFunc (myInstance);

because it will give a compile time error of cannot convert from 'MyClass' to 'byte[]'

So even though, through the very nice functionalty of indexers, I can access the class as an array, I still can't pass it as an array. Is there a way that I'm just not aware of?

Not really. What is happening is all just syntactic sugar. It looks like an array but you know that it isn't really an array. Therefore, if you want it to be an array you have to convert it to one.

My suggestion would be to add a method called GetAsByteArray() or similar and the contents of the method would create and return this byte array.

Returning the internal buffer should be avoided as it would be possible for something outside your class to modify the contents and your class wouldn't know about it. That would break the encapsulation aspect of OO.

Thanks Colin,

I was starting to think that I should probably use something like a GetAsByteArray() method but then it occured to me that it should be possible to override the implicit cast operator and would you believe!

I now have the following piece of code in my class:

static public implicit operator byte[](MyClass m)
{
   return (byte[])m.buffer.Clone();
}

... and Bob's your uncle.

The reason I'm using the Clone() method of Array is so that I don't pass the array reference itself which, as you pointed out, would break the aspect of encapsulation.
