changing a received file location in c# socket -

i have created tcp server in c# receives file client , keeps in current directory. code segment 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 , saved in " + environment.currentdirectory); 

where cmdfilename received filename.

now have created folder named "test" inside current directory using following code:

            string root = environment.currentdirectory;             string folder = path.combine(root,"test");             if (!directory.exists(folder)) directory.createdirectory(folder); 

i want keep received file inside "test" folder. need make change following line of previous code segment:

using (filestream fstream = new filestream(path.getfilename(cmdfilename), filemode.create)) 

but change have make?

you using path.combine path of new test directory--you need use again find path of cmdfilename file inside test directory:

string cmdfilepath = path.combine(folder, path.getfilename(cmdfilename)); using (filestream fstream = new filestream(cmdfilepath, filemode.create))
