The stream is basically the sequence of bytes passing through the communication path. There are two main streams: the input stream and the output stream . The input stream is used for reading data from file (read operation) and the output stream is used for writing into the file (write operation). From the above definition of file, the C# provides a namespace that enable us to manipulate file in C# called System.IO. System.IO is a namespace and it contains a standard IO (input/output) types such as classes , structures , enumerations , and delegates to perform a read/write operations on different sources like file, memory, network, etc. System.IO Classes The table below shows differen...
