I have created a TCP server in c# which receives a file from a client and keeps it in the current directory. The code segment which does this is as follows:
using (FileStream fStream = new FileStream(Path.GetFileName(cmdFileName), FileMode.Create))
{
fStream.Write(buffer, 0, buffer.Length);
fStream.Flush();
fStream.Close();
}
Console.WriteLine("File received and saved in " + Environment.CurrentDirectory);
where cmdFileName is the received filename.
Now I have created a folder named "test" inside the current directory using the following code:
string root = Environment.CurrentDirectory;
string folder = Path.Combine(root,"test");
if (!Directory.Exists(folder)) Directory.CreateDirectory(folder);
I want to keep the received file inside the "test" folder. I need to make change to the following line of my previous code segment:
using (FileStream fStream = new FileStream(Path.GetFileName(cmdFileName), FileMode.Create))
But what change will I have to make?
You are using Path.Combine
to get the path of the new test
directory--you just need to use it again to find the path of the cmdFileName
file inside the test
directory:
string cmdFilePath = Path.Combine(folder, Path.GetFileName(cmdFileName));
using (FileStream fStream = new FileStream(cmdFilePath, FileMode.Create))
After this code:
string root = Environment.CurrentDirectory;
string folder = Path.Combine(root,"test");
if (!Directory.Exists(folder)) Directory.CreateDirectory(folder);
Add another usage of the Path.Combine
since you want to attach the path folder
to the file cmdFileName
:
string fullFilePath = Path.Combine(folder, Path.GetFileName(cmdFileName));
using (FileStream fStream = new FileStream(fullFilePath, FileMode.Create))
{
...
}
Console.WriteLine("File received and saved in " + fullFilePath);
Also you should want to do it inside a try
block in order to announce that it succeeded only if it really did:
try
{
using (FileStream fStream = new FileStream(fullFilePath, FileMode.Create)) //Exception accessing the file will prevent the console writing.
{
...
}
Console.WriteLine("File received and saved in " + fullFilePath);
}
catch (...){...Console.WriteLine("Could not write to file " + fullFilePath);...}
