Any data previously written to the buffer is copied to the file before the file stream is closed, so it is not necessary to call Flush before invoking Close.
ComVisibleAttribute SerializableAttribute Examples The following example shows how to use a StreamWriter object to write a file that lists the directories on the C drive, and then uses a StreamReader object to read and display each directory name.
A good practice is to use these objects in a using statement so that the unmanaged resources are correctly disposed. The using statement automatically calls Dispose on the object when the code that is using it has completed.
The constructor used in this example is not supported for use in Windows Store Apps. GetDirectories ' Write each directory name to a file.
Name Next End Using 'Read and show each line from the file. Important This type implements the IDisposable interface. When you have finished using the type, you should dispose of it either directly or indirectly. To dispose of it indirectly, use a language construct such as using in C or Using in Visual Basic.
The default UTF-8 encoding for this constructor throws an exception on invalid bytes. This behavior is different from the behavior provided by the encoding object in the Encoding. To specify a BOM and determine whether an exception is thrown on invalid bytes, use a constructor that accepts an encoding object as a parameter, such as StreamWriter String, Boolean, Encoding or StreamWriter.
By default, a StreamWriter is not thread safe. Synchronized for a thread-safe wrapper.C#:: StreamReader And StreamWriter - Overwriting Specific Line In A File?
Apr 10, I am currently working on a small project, which is an ATM simulator but, lately, I've been stuck in a part where I have to overwrite a specific line in r-bridal.com file to update the account's checking and savings balance, once the transaction has been done.

MSDN is not % clear, but Jon Skeet is saying "Flush", so do it before close/dispose.
It won't hurt, right? From r-bridal.com Method. Any data previously written to the buffer is copied to the file before the file stream is closed, so it is not necessary to call Flush before invoking Close.
Note: In NT batch files, the │ in the non-NT help is a vertical line extended ASCII character (character in codepage ). It is used because in non-NT Windows versions and in "real" DOS there is no way to escape a "real" pipe symbol.
