Yes - the Save method is the one to use.
Two things to note though:
1) Don't try to save it to the root directory - Vista and above won't let you write to the root of the boot drive to help prevent virus and trojan attacks - use a different directory unless you app has admin privileges.
2) Be careful what format you save the image in: many types including JPG are lossy compression, so each time you save and open it you will get a fuzzier, less detailed image. Use BMP or similar for working images, and JPG for final presentation only.
If you get an email telling you that you can catch Swine Flu from tinned pork then just delete it. It's Spam.

Fascinating. Thanks for sharing.

That's bad news.
Perhaps if you shared what you've done, with relevant source code on, say, a site targeted at c# developers, they'd be able to help you

The quality of the question you ask directly dictates the quality of the answer you get.
Your question was so bad that the only possible answers were sarcasm. in other words, your question was nothing but a jumble of random words.

Open your question and have a look at it.
Here's what I, the idiot on the other side of planet, see when I read this question.
- descriptive subject of the topic "hi". Yup, this tells me EXACTLY what I need to know about your question. (figuratively it actually does)
- C# contents of the question considering we're in the C# forum. None.
- Actual coding question. "can i get coding". Answer: Somehow you probably can, the sky is the limit.
- "segmenting overlapped and touching chromosomes" reads as "dkjsgfgf dkjsghfdaskjgfaskdsvf dhgfwkevfwvfkev ewkrhvewk" to me or it could be Klingon, or Ferengi or something else. How should anyone with a normal background in IT know what this is about? it is not unuseful, but it doesn't help in this case, add more context.
- "using hierarchical distributed genetic algorithm for image segmentation" what is this? Can YOU answer this question? My first thought, if I would need this, is to google it and see if I can get some more information. Then I would be able to clarify this to the people I'm asking questions to.
Your question seems to state you want a complete answer and solution to the problem. Wrong forum. Here we try to help people who get stuck with a specific problem they encountered and researched and tried to resolve themselves.
Do some research, get started and come back if you have more information.

i got few line of code where configure method is calling and passing just the string value but ConfigureWith function expect delegate. can anyone help me to understand how ConfigureWith() method will work. thanks
MailTemplate
.ConfigureWith(mt => mt.MailBody = "hello world")
.ConfigureWith(mt => mt.MailFrom = "rdingwall@gmail.com")
.DoSomeOtherStuff()
.Build();
The implementation for this would be:
public class MailTemplate
{
// regular auto properties
public string MailFrom { get; set; }
public string MailBody { get; set; }
public MailTemplate ConfigureWith(Action<mailtemplate> func)
{
func(this);
return this;
}
}

MailTemplate
.ConfigureWith(mt => mt.MailBody = "hello world")
.ConfigureWith(mt => mt.MailFrom = "rdingwall@gmail.com")
.DoSomeOtherStuff()
.Build();
How did you "dream up" this code? Where is the MailTemplate class instantiated? Is "MailTemplate" a static method that returns one of those classes?
You're complicating things a bit. What are you trying to achieve? Wouldn't below suffice and be a bit more readable?
public class MailTemplate
{
public string MailFrom { get; set; }
public string MailBody { get; set; }
}
class Program
{
static void Main()
{
var x = new MailTemplate()
{
MailBody = "hello world",
MailFrom = "rdingwall@gmail.com"
};
x.DoSomethingElse();
x.Build;
Console.ReadLine();
}
}

The caller is not passing just the string value. He/she is calling the property setter with a string value. In the call func(this) the this pointer takes the place of the mt in the Lambda Expression.
Personally, I wouldn't do it that way. The properties are public, so they can just as well be assigned directly. And if something goes wrong, you have at least a chance to debug the intermediate states when you use seperate statements instead of putting all into one.

Hi I am working on file io and am getting an io exception the process cannot access the file it's in use by another process.
I tried to closed all streams. I'm baffled please help.
Here is my code:
DateTime dt = DateTime.Now.Date;
try
{
string fileLocation = "C:\\pprdate.txt";
FileStream fs = null;
if (!File.Exists( fileLocation ))
{
using (fs = File.Create( fileLocation ))
{
fs.Close();
fs = null;
}
}
string line = null;
TextReader readFile = new StreamReader(fileLocation);
while (true)
{
line = readFile.ReadLine();
if (line != null)
{
DateTime sd = DateTime.Parse( line );
if (dt >= sd.AddDays( 16 ))
{
sd = sd.AddDays( 30 );
StartDate.Text = sd.ToShortDateString();
EndDate.Text = sd.AddDays( 30 ).ToShortDateString();
}
readFile.Close();
readFile = null;
}
else
{
TextWriter writeFile = new StreamWriter(fileLocation);
DateTime sd = dt.AddDays( 7 );
writeFile.WriteLine( sd );
StartDate.Text = sd.ToShortDateString();
EndDate.Text = sd.AddDays( 30 ).ToShortDateString();
writeFile.Close();
writeFile = null;
}
}

If I'm looking correctly, you try to open a StreamWriter to the same fileLocation you already have opened a StreamReader.
For example if the line variable is null, you don't close the reader since it's inside the if statement:
...
if (line != null)
{
DateTime sd = DateTime.Parse( line );
if (dt >= sd.AddDays( 16 ))
{
sd = sd.AddDays( 30 );
StartDate.Text = sd.ToShortDateString();
EndDate.Text = sd.AddDays( 30 ).ToShortDateString();
}
readFile.Close();
readFile = null;
}
else ...
You didn't explain the overall idea you're trying to accomplish so I'm not able to sae what would be a good correction to the code, but I encourage to use using[^] statement to ensure proper disposing etc.

This is utterly useless. There are options when opening a file that will create it if it doesn't exist already, so creating the file, just to close it is pointless.
Secondly, the using statement will automatically Dispose (which calls Close on a file oject) when the using block exits. So calling Close and then setting fs to null just duplicates code that is already there.
