Hi Guys,
I am trying to delete a file via C#.NET console application. As you all know, that in C programming we have a function called 'remove' which deletes any particular file, as allocated to. I know that we also have something like that in C#, but I am unable to make it out. I want to delete the file of the following path:
D:/My Folder/xxxx.txt
Please Help me out! Your help will be appreciated....thanx for taking interest in my question.
|
|
|
|
|
System.IO.File.Delete(@"D:/My Folder/xxxx.txt");
|
|
|
|
|
Thanx freak!
It really worked! 
|
|
|
|
|
|
Using this:
File.Delete("D:/My Folder/xxxx.txt");
|
|
|
|
|
You can look at the FilInfo Class. Something like this.
private void DeleteFiles()
{
DirectoryInfo info = new DirectoryInfo(this.textBox1.Text);
foreach (FileInfo info2 in info.GetFiles("*.done"))
{
File.Delete(info2.FullName);
}
MessageBox.Show("Completed Processing", "Processing Info", MessageBoxButtons.OK, MessageBoxIcon.Asterisk);
}
Hope this helps.

This is such a common thing that I'd be willing to bet that someone, somewhere, must have done it before. What do you think?
For goodness sake learn to use Google 'calculate age c#' should do the trick.

If the certificate (or certificates) are embedded in the signature you can extract the public key from that certificate. Be wary that a signature can have more than on certificate included, this happens when you include the whole chain and not just the certificate used to sign.

Will it always have that many characters? If it does, you can use value.Substring(12, 4); If the location of the periods change, you can use IndexOf to find their location and use that within Substring.
Hope that helps,

arsing strings differs greatly depending on the strongs you have to parse.
If you know the format will always be the same, i.e. "." marks the beginning and again the end of the value you want to retrieve, you can IndexOf() to get these positions and then use them to calcualte the substring that can contsin a vaule.
Then use int.Tryparse (all number types have TryParse methods) to convert the value to a number.
Thhis methods returns a bool that tells you if the parsing was successful or not.

If the format of the string is always the same, and there are only ever going to be two '.'s in it then use String.Split.
Off the top of my head something like:
string[] parts = myinputstring.Split(".".ToCharArray());
string numericBit = parts[1];
Hope this helps.
But as I have done this from memory, PLEASE look up the Split Method first.

Your memory is exaggerating the method's complexity. The method accepts a char[] but since the parameter is defined with the params keyword a simple Split('.') would suffice.

I would like to start off by saying that I have never done this before, so please excuse if this is a silly mistake.
I have a function within a DLL that I need to call. The C# project will fail on occasion with an exception, "Attempted to read or write protected memory. This is often an indication that other memory is corrupt." I have been looking around, and my best guess is using strings in my project will cause errors.
Any help from the experts?
Here's the code I'm using in C#
public class Encryption
{
[DllImport("Encryption.dll", EntryPoint = "encrypt")]
public unsafe static extern IntPtr encrypt(char [] data, char [] key);
static public string Encrypt(string data, string key)
{
if (data.Length > 0)
{
return Marshal.PtrToStringAnsi(encrypt(data.ToCharArray(), key.ToCharArray()));
}
else
return "";
}
}
And the function in the DLL (C++)
extern "C"
{
__declspec(dllexport) string encrypt(char* data, char* key)
{
...
}
}
Thanks,
-Kalivos

Hello. What's that string thingy? Did you mean std::string? If so, I don't think it's possible to import it since encrypt function is not returning a POD. My guess is that you should either change std::string to a char* or use C++/CLI instead.
As said, it's only my guess. Perhaps others could aid you better.
