Writing the contents of a Memory Location (intPtr) to a text file

I am just adding this function so that others can use it if needed...
public static void WriteToFile(IntPtr iPtr,int size,string sFileName)
{
if(sFileName.Trim().Length == 0)
sFileName = @"C:\DefaultLoc.txt";
Byte[] Contents = new Byte[size];
Marshal.Copy(iPtr, Contents, 0, size);
System.IO.FileStream fs = new System.IO.FileStream(sFileName , System.IO.FileMode.Create);
foreach (Byte bt in Contents)
fs.WriteByte(bt);
fs.Flush();
fs.Close();
}

Suppose you have two variables:
IntPtr ptr; // pointer
int size; // number bytes in the memory block
Code:
Byte[] byteArray = new Byte[ n ];
Marshal.Copy(ptr, byteArray, 0, n);
Now all bytes from unmanaged memory block are copied to byteArray, and you can to handle this array by the way you need.
