Close a stream for System.IO.Copy

Question

Hello
I have this code. I want close this stream, because I have this Error in another place of my program.
ERROR: word cannot save this file because it is already open elsewhere
string sourceFile = richTextBox_I.Text;
string destFile = Application.StartupPath + @"\UserImages\" + name;
System.IO.File.Copy(sourceFile, destFile, true);

Answer 1

I used the following code. Now I do not have any problem:
string pathSource = richTextBox_I.Text;
string pathNew = Application.StartupPath + @"\UserImages\" + name;
try
using (FileStream fsSource = new FileStream(pathSource,
FileMode.Open, FileAccess.Read))
// Read the source file into a byte array.
byte[] bytes = new byte[fsSource.Length];
int numBytesToRead = (int)fsSource.Length;
int numBytesRead = 0;
while (numBytesToRead > 0)
// Read may return anything from 0 to numBytesToRead.
int n = fsSource.Read(bytes, numBytesRead, numBytesToRead);
// Break when the end of the file is reached.
if (n == 0)
break;
numBytesRead += n;
numBytesToRead -= n;
numBytesToRead = bytes.Length;
// Write the byte array to the other FileStream.
using (FileStream fsNew = new FileStream(pathNew,
FileMode.OpenOrCreate, FileAccess.Write))
fsNew.Write(bytes, 0, numBytesToRead);
catch (FileNotFoundException ioEx)
MessageBox.Show(ioEx.Message);
