The following table shows common stream member functions:. A FileStream instance is used to read or write data to or from a file.

In order to construct a FileStream , first we need a file that we want to access; second, the mode that indicates how we want to open the file; third, the access that indicates how we want to access a file; and finally, the share access, which specifies whether you want exclusive access to the file. The FileStream can read or write only a single byte or an array of bytes. You will be required to encode the System.

String type into a corresponding byte array. Text namespace defines a type named encoding that provides members that encode and decode strings to an array of bytes. Once encoded, the byte array persists with the FileStream. Write method. To read the bytes back into memory, you must reset the internal position of the stream and call the ReadByte method. Finally, you display the raw byte array and the decoded string to the console:.

GetBytes msg ; fs. Write byteArray, 0, byteArray. Length ; fs. ReadByte ; Console. The BinaryReader and BinaryWriter classes allow you to read and write discrete data types to an underlying stream in a compact binary format. The BinaryWriter class defines a highly overloaded Write method to place a data type in the underlying stream.

The following sample first writes data contents to a new champu. Later, to read the, BinaryReader class employs a number of methods, as follows:. WriteLine br. ReadInt32 ; Console. We can use StringWriter and StringReader to treat textual information as a stream of in-memory characters. This can prove helpful when you wish to append character-based information to an underlying buffer. The following code sample illustrates this by writing a block of string data to a StringWriter object, rather than to a file on the local hard drive:.

This article began by introducing the. NET file system and its detailed class hierarchy. We have learned to manipulate a physical file or directory on the hard drive by using File and Directory class. Next, we examined the Stream class in detail.

So this article gives you a full understanding of how to access data from the hard drive and write it back. A new tab for your requested boot camp pricing will open in 5 seconds.

Topics Reverse engineering File system manipulation Reverse engineering File system manipulation. DriveInfo This class contains detailed information regarding the drives that a given machine uses. FileStream This represents random file access data as a stream of bytes.

Path This performs operations on System. String types that contain file or directory path information in a platform-neutral manner. However, the underlying storage is a string buffer rather than a physical file.

BufferedStream This class provides temp storage for a stream of bytes that you can commit to storage at a later time. Seek Sets the position in the current stream. Position Determines the current position in the current stream. Length Returns the length of the stream in bytes. Flush Updates the underlying data source with the current state of the buffer and then clears the buffer. Close Closes the current stream and release any associated stream resources.
