how to split and merge file

try this code

privateboolSplitter(stringstrFileName,stringstrPathName,longlgSize)
{
...
prgbProgress.Step=(int)System.Math.Ceiling(((float)FileSize/10));
//splitittopartsinafolderCalled"FileName"
System.IO.Directory.CreateDirectory(strDirectory);
//beginwriting
while(FSIn.Position!=FSIn.Length)
{
PreDefinedCacheSize=8192;
byte[]buffer=newbyte[PreDefinedCacheSize];
strNewFileNames=strDirectory+"//"+intCounter.ToString()+
".part"+intCounter.ToString()+".part";
FSout=newFileStream(strNewFileNames,FileMode.Create);
BinaryWriterwFSOut=newBinaryWriter(FSout);
while((FSout.Position
{
prgbProgress.Value=(int)(((float)FSIn.Position/
(float)FSIn.Length)*(float)prgbProgress.Maximum);
if(((FSIn.Length-FSIn.Position)
(int)lgSize))&&(PreDefinedCacheSize>lgSize))
{
PreDefinedCacheSize=(int)FSIn.Length-(int)FSIn.Position;
rFSIn.Read(buffer,0,PreDefinedCacheSize);
wFSOut.Write(buffer);
Thread.Sleep(1);
}
else
{
if(PreDefinedCacheSize>lgSize)PreDefinedCacheSize=(int)lgSize;

}
wFSOut.Close();

intCounter++;
}
//finish
MessageBox.Show("Done!!splitting"+strFileName,"Splitter");
