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.

Then I created an object of FileStream class fs to create a new csharpfile.Yes, you can also use StreamWriter, which as you say provides more symmetry, though also more code. You need to call Flush() to complete the write, and you also need to reset the Stream position to zero when starting the read.
May 03, · // Example #3: Write only some strings in an array to a file. // The using statement automatically flushes AND CLOSES the stream and calls // schwenkreis.come on the stream object. // NOTE: do not use FileStream for text files because it writes bytes, but StreamWriter .
