How to use C# FileStream Class
The FileStream Class serves as a representation of a file on a computer system. It provides functionality to perform operations such as reading from, writing to, opening, and closing files within a file system. Additionally, it enables manipulation of other file-related operating system handles, including pipes, standard input, and standard output.
One of the key features of the FileStream Class is its ability to facilitate the movement of data to and from the stream using arrays of bytes. This allows for efficient handling of file data, enabling operations such as reading a file's contents into memory or writing data from memory to a file. By working with byte arrays, developers have granular control over the manipulation of file data.Some of FileModes as Follows :
- FileMode.Append : Open and append to a file if the file does not exist , it create a new file.
- FileMode.Create : Create a new file , if the file exist it will append to it.
- FileMode.CreateNew : Create a new File , if the file exist , it throws exception.
- FileMode.Open : Open an existing file.
How to create a file using C# FileStream Class?
To work with files using the FileStream Class, developers can utilize the FileMode enumeration, which provides various options for how files should be accessed or created. For instance, FileMode can specify whether a file should be opened for reading, writing, or both. It can also determine whether a new file should be created if it does not exist or whether an existing file should be overwritten.

By using the capabilities of the FileStream Class, developers can effectively interact with files in a file system, performing tasks such as reading and writing data, managing file handles, and manipulating file access modes. This flexibility and control over file operations enable the creation of robust file-based functionalities within C# applications.
The FileStream Class in C# serves as a versatile tool for file manipulation, providing the ability to read from, write to, open, and close files on a file system. Through its integration with the FileMode enumeration, developers can precisely control file access and create, modify, or read file data efficiently using byte arrays.
